Multiple Views in Sinlge List with ListView and Other Control - Hotel Menu Example

In this Code We will use multiple Views in a single list as well as put a Button below the list which use to show how many items will be selected in another new Activities.

1. First We will create the layout of each row as follows layout/rowlayout.xml.
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   	android:orientation="horizontal" android:layout_width="fill_parent"
   	android:layout_height="fill_parent">
   	
   	<ImageView android:layout_height="60px" 
   		android:id="@+id/imageView1"
   		android:layout_width="60px" 
   		android:src="@drawable/icon" 
   		android:maxWidth="5px"
   		android:minWidth="5px"
   		/>
   	<TextView android:text="TextView" 
   		android:layout_width="200dp"
   		android:layout_height="wrap_content" 
   		android:id="@+id/textView1"
   		android:lines="2"
   		android:layout_marginLeft="10px"
   		android:layout_marginTop="10px" 
   		android:textSize="15px"
   		></TextView>
   	<CheckBox android:text="" 
   	android:id="@+id/checkBox1" 
   	android:layout_width="wrap_content" 
   	android:layout_height="wrap_content" />
   	
   </LinearLayout>
   

2. Than we create our main layout as follows layout/main.xml
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:orientation="vertical"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       >
   <ListView 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:id="@android:id/list"
       />
     <Button android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:id="@+id/btnOrder" 
       android:text="Order" 
       android:layout_gravity="center"/>
   </LinearLayout>
   

   Here the name of the listView must be as aboves : "@android:id/list" where android list will be automatically placed when we add the adapter in our activity class.
3. Then we create a class which extend the ArrayAdapter  class as follows.
   

    
   package com.container;
   
   import android.content.Context;
   import android.view.LayoutInflater;
   import android.view.View;
   
   import android.view.ViewGroup;
   import android.widget.ArrayAdapter;
   import android.widget.CheckBox;
   import android.widget.CompoundButton;
   import android.widget.CompoundButton.OnCheckedChangeListener;
   import android.widget.ImageView;
   import android.widget.TextView;
   
   import com.container.R;
   
   public class HotelMenuAdapter extends ArrayAdapter<String> {
   	Context context;
   	String[] values;
   	int position;
   	boolean itemSelected[] = { false, false, false, false, false, false };
   
   	public HotelMenuAdapter(Context context, String[] values) {
   		super(context, R.layout.rowlayout, values);
   		this.context = context;
   		this.values = values;
   	}
   
   	public View getView(final int positon, View convertView, ViewGroup parent) {
   		LayoutInflater inflater = (LayoutInflater) context
   				.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   		View rowView = inflater.inflate(R.layout.rowlayout, parent, false);
   
   		TextView textView = (TextView) rowView.findViewById(R.id.textView1);
   		ImageView image = (ImageView) rowView.findViewById(R.id.imageView1);
   		final CheckBox checkBox = (CheckBox) rowView
   				.findViewById(R.id.checkBox1);
   
   		image.setOnClickListener(new View.OnClickListener() {
   
   			public void onClick(View v) {
   				// TODO Auto-generated method stub
   				// Toast.makeText(context, ((TextView)v).getText().toString(),
   				// 5).show();
   				if (checkBox.isChecked()) {
   					checkBox.setChecked(false);
   					itemSelected[positon] = false;
   				} else {
   					checkBox.setChecked(true);
   					itemSelected[positon] = true;
   				}
   			}
   		});
   
   		textView.setOnClickListener(new View.OnClickListener() {
   
   			public void onClick(View v) {
   				// TODO Auto-generated method stub
   				// Toast.makeText(context, ((TextView)v).getText().toString(),
   				// 5).show();
   				if (checkBox.isChecked()) {
   					checkBox.setChecked(false);
   					itemSelected[positon] = false;
   				} else {
   					checkBox.setChecked(true);
   					itemSelected[positon] = true;
   				}
   			}
   		});
   
   		checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   
   			public void onCheckedChanged(CompoundButton buttonView,
   					boolean isChecked) {
   				// TODO Auto-generated method stub
   				// Toast.makeText(context, String.valueOf(positon), 5).show();
   				if (isChecked) {
   					itemSelected[positon] = true;
   					// Toast.makeText(context, "Checked", 5).show();
   				} else {
   
   					itemSelected[positon] = false;
   					// Toast.makeText(context, "Not Checked", 5).show();
   				}
   
   			}
   		});
   
   		textView.setText(values[positon]);
   		switch (positon) {
   		case 0:
   			image.setImageResource(R.drawable.a);
   			break;
   		case 1:
   			image.setImageResource(R.drawable.b);
   			break;
   		case 2:
   			image.setImageResource(R.drawable.c);
   			break;
   		case 3:
   			image.setImageResource(R.drawable.d);
   			break;
   		case 4:
   			image.setImageResource(R.drawable.e);
   			break;
   		case 5:
   			image.setImageResource(R.drawable.f);
   			break;
   		case 6:
   			image.setImageResource(R.drawable.g);
   			break;
   
   		}
   
   		checkBox.setChecked(false);
   		return rowView;
   	}
   
   	public boolean[] getItemSelected() {
   		return itemSelected;
   	}
   
   	public void setItemSelected(boolean[] itemSelected) {
   		this.itemSelected = itemSelected;
   	}
   
   }
   

   In this class we also add the listeners for the ImageView, TextView as well as CheckBoxes.
   
   
4. Then in our main Activity class we will extends the ListActivity class as follows.
   
   

   package com.container;
   
   import android.app.ListActivity;
   import android.content.Intent;
   import android.os.Bundle;
   import android.view.View;
   import android.widget.Button;
   import android.widget.CheckBox;
   import android.widget.Toast;
   
   public class HotelMenuDemoActivity extends ListActivity {
   	/** Called when the activity is first created. */
   	String[] values = { "McVeggie~Rs.40-50", "McAloo Tikki~Rs 20–50",
   			"Paneer Salsa~Rs 20–50", "Crispy Chinese~Rs 20–50",
   			"McCurry Pan~Rs 20–50", "Chicken Maharaja Mac", };
   	Button btnOrder;
   	CheckBox chBox;
   	HotelMenuAdapter menuAdapter;
   
   	
   	@Override
   	public void onCreate(Bundle savedInstanceState) {
   		super.onCreate(savedInstanceState);
   		setContentView(R.layout.main);
   		
   		menuAdapter = new HotelMenuAdapter(getApplicationContext(), values);
   		setListAdapter(menuAdapter);
   
   		btnOrder = (Button) findViewById(R.id.btnOrder);
   		btnOrder.setOnClickListener(new View.OnClickListener() {
   
   			public void onClick(View arg0) {
   				// TODO Auto-generated method stub
   				boolean [] selectedItem=menuAdapter.getItemSelected();
   				int count=0;
   				Intent intent=new Intent(getApplicationContext(),ShowOrderActivity.class);
   				for(int i=0;i<selectedItem.length;i++){
   					if(selectedItem[i]==true){
   						count++;
   						intent.putExtra("items",values);
   						intent.putExtra("selected",selectedItem);
   				//	Toast.makeText(getApplicationContext(), menuAdapter.getItem(i),5).show();
   					}
   				}
   				startActivity(intent);
   			}
   		});
   
   	}
   }




5. Finally We will create the another activity which just show the items witch is selected. as follows. 
   
   

   package com.container;
   
   import android.app.Activity;
   import android.os.Bundle;
   import android.widget.TextView;
   
   public class ShowOrderActivity extends Activity {
   
   	/** Called when the activity is first created. */
   	@Override
   	public void onCreate(Bundle savedInstanceState) {
   		super.onCreate(savedInstanceState);
   
   		TextView tv = new TextView(this);
   		tv.setMaxLines(10);
   		Bundle b = getIntent().getExtras();
   		String order = "Your Order is : \n";
   		String[] values = (String[]) b.getSerializable("items");
   		boolean[] items = (boolean[]) b.getSerializable("selected");
   		if (items != null && values != null) {
   			for (int i = 0; i < values.length; i++) {
   				if (items[i] == true)
   					order += values[i] + ",\n";
   			}
   		}
   		tv.setText(order);
   		setContentView(tv);
   		// TODO Auto-generated method stub
   	}
   
   }
   

That's the code:

• When you click on the ImageView,TextView or Checkbox  corresponding Checkbox will be checked or unchecked in reverse state.  as follows
  
  
  
• After selecting which ever items you want click on "Order" Button than following  output will be displayed. 

Android TabLayout example

In this example we have three tab as follows. you can move in the any tab at by clicking on the Tab. as follows

Download Android Tab Layout :Example Code

1. First we design the XML layout as follows
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout android:id="@+id/linearLayout1"
     android:layout_width="match_parent" android:layout_height="match_parent"
     android:orientation="vertical">
     <TabWidget android:layout_width="match_parent"
      android:layout_height="wrap_content" 
      android:id="@android:id/tabs"></TabWidget>
     <FrameLayout android:layout_width="match_parent"
      android:layout_height="match_parent" android:id="@android:id/tabcontent">
      
     </FrameLayout>
    </LinearLayout>
   </TabHost>
   
   

   
   
   
2.  Create the Activtity file for diffrent Tab Activities we have create three diffrent Activity : ActivityA, ActivityB, ActivityC as follows




package com.container;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class ActivityA extends Activity {

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     TextView tv=new TextView(this);
     tv.setText("I am in Tab A..");
     setContentView(tv);
     // TODO Auto-generated method stub
 }

}

package com.container;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class ActivityB extends Activity {

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     TextView tv=new TextView(this);
     tv.setText("I am in Tab B..");
     setContentView(tv);
     // TODO Auto-generated method stub
 }

}

package com.container;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class ActivityC extends Activity {

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     TextView tv=new TextView(this);
     tv.setText("I am in Tab C..");
     setContentView(tv);
     // TODO Auto-generated method stub
 }

}

3. Than we Create Our main Activity as follows code..




package com.container;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;

public class TabViewDemoActivity extends TabActivity {
    /** Called when the activity is first created. */
 Resources res;
 TabHost tabHost;
 TabHost.TabSpec spec;
 Intent intent;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        res=getResources();
        tabHost=getTabHost();
        
        /**Create Tab A**/
        intent=new Intent().setClass(this,ActivityA.class);
        spec=tabHost.newTabSpec("A")
          .setIndicator("A",res.getDrawable(R.drawable.ic_btn_speak_now))
          .setContent(intent);
        tabHost.addTab(spec);
        
        /**Create Tab B**/
        intent=new Intent().setClass(this,ActivityB.class);
        spec=tabHost.newTabSpec("B")
          .setIndicator("B",res.getDrawable(R.drawable.ic_btn_speak_now))
          .setContent(intent);
        tabHost.addTab(spec);
        
        /**Create Tab C**/
        intent=new Intent().setClass(this,ActivityC.class);
        spec=tabHost.newTabSpec("C")
          .setIndicator("C",res.getDrawable(R.drawable.ic_btn_speak_now))
          .setContent(intent);
        tabHost.addTab(spec);
    }
}

that it, Run your app you can move on any Tab By clicking on that as follows

Android Custom ArrayAdapte-ListView - Example Code

In this Example we show how to Add Multiple View in the Single Row of the ListView Control. We take two Controls ImageView and TextView as Shown follows.

Download Custom ArrayAdapte-ListView - Code Example

1. First We Create the layout file for the following that is as fllows : res/layout/rawlayout.xml
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <ImageView android:layout_height="wrap_content" 
     android:id="@+id/imageView1"
     android:layout_width="wrap_content" 
     android:src="@drawable/icon" />
   
    <TextView android:text="TextView" 
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" 
     android:id="@+id/textView1" 
     android:layout_marginLeft="10px"
     android:layout_marginTop="10px" 
     android:textSize="20px"
     ></TextView>
   
   </LinearLayout>
   
   

   
   
2.  Then We Create The Custom ArrayAdapter Class Which will create by extending ArrayAdapter Class that has a getView() method that use to set how we want customize our row layout of  for each raw of ListView
   
   

   package com.container;
   
   import android.content.Context;
   import android.view.LayoutInflater;
   import android.view.View;
   import android.view.ViewGroup;
   import android.widget.ArrayAdapter;
   import android.widget.ImageView;
   import android.widget.TextView;
   
   public class MyArrayAdapter extends ArrayAdapter<String> {
    Context context;
    String[] values;
   
    public MyArrayAdapter(Context context, String[] values) {
     super(context, R.layout.rowlayout, values);
     this.context = context;
     this.values = values;
    }
   
    public View getView(int positon, View convertView, ViewGroup parent) {
     LayoutInflater inflater = (LayoutInflater) context
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
     View rowView = inflater.inflate(R.layout.rowlayout, parent, false);
   
     TextView textView = (TextView) rowView.findViewById(R.id.textView1);
     ImageView image = (ImageView) rowView.findViewById(R.id.imageView1);
   
     textView.setText(values[positon]);
     if (positon % 2 == 0) {
      image.setImageResource(R.drawable.yes);
     } else {
      image.setImageResource(R.drawable.no);
     }
     return rowView;
    }
   }
   

   
   
   
3. Then We create the Our Activity Class which extends the ListActivity class in which we have set the Adapter of using the method  setListAdapter() which has an argument of our own MyArrayAdapter class instance.
   
   
   

   package com.container;
   
   import android.app.ListActivity;
   import android.os.Bundle;
   import android.view.View;
   import android.widget.ListView;
   import android.widget.Toast;
   
   
   public class MultipleViewListActivity extends ListActivity{
       
    String [] values= {"Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2"};;
    
       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           
           setListAdapter(new MyArrayAdapter(getApplicationContext(), values));
       }
   
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
     // TODO Auto-generated method stub
     Toast.makeText(getApplicationContext(), values[position], 5).show();
     //super.onListItemClick(l, v, position, id);
    }
   }

When you click on any of the ListItem than The Toast is appear with the Name in that TextView.

Android GridView tutorial and Example Code

GridView:

• Contains a horizontally scrolling list of View objects, also often used with image icons; the user can select an item to perform some action upon.

Download Android GridView Container :Example Code

Let's take Simple Example which shows the Grid of  TextView that will be display as grid on Screen and you can select on of them. 

The Layout of this app is as follows : main.xml 

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridView01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:columnWidth="90dp"
    android:numColumns="2"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:stretchMode="columnWidth"
    android:gravity="center"
    />

The Java file can be as follows.

 
package com.container;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class GridViewContainerActivity extends Activity {
    /** Called when the activity is first created. */
    GridView gv;
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        String [] colors= {"Red","Green","Blue","Pink","Gray"};
        gv=(GridView)findViewById(R.id.gridView01);
        
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_gallery_item, colors);
        gv.setAdapter(adapter);
        gv.setNumColumns(3);
        gv.setBackgroundColor(Color.CYAN);
        gv.setGravity(Gravity.CENTER);
        gv.setOnItemClickListener(new OnItemClickListener() {

   public void onItemClick(AdapterView<?> myAdapter, View view, int myItemId,
     long myLang) {
    // TODO Auto-generated method stub
    
    String selectedItem=gv.getItemAtPosition(myItemId).toString();
  
    Toast.makeText(getApplicationContext(), selectedItem, 2).show();
   }
  });
    }
}

When you first run your app that will shown as follows.

 For example you select "Green" than following output will be displayed.

Android Galary Container : Code Example

    /** Called when the activity is first created. */
 Gallery g;
 TextView tv;
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        String [] colors= {"Red","Green","Blue","Pink","Gray"};
        g=(Gallery)findViewById(R.id.gallary01);
        tv=(TextView)findViewById(R.id.textView1);
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_gallery_item, colors);
        g.setAdapter(adapter);
        
        g.setOnItemClickListener(new OnItemClickListener() {

   public void onItemClick(AdapterView<?> myAdapter, View view, int myItemId,
     long myLang) {
    // TODO Auto-generated method stub
    
    String selectedItem=g.getItemAtPosition(myItemId).toString();
    tv.setText("You Selected: "+ selectedItem);
    Toast.makeText(getApplicationContext(), selectedItem, 2).show();
   }
  });
    }
}

When you first run your app that will shown as follows.

 You can scroll horizontally using touch.

 For example you select "Green" than following output will be displayed.

Android Content Menu using XML file and Event Handling- Example

Context Menu :

• The ContextMenu is a subtype of Menu that you can configure to display when a long press is performed on a View. As the name implies, the ContextMenu provides for contextual menus to display to the user for performing additional actions on selected items. 
• You need to implement the onCreateContextMenu() method of your Activity for one to display. However, before that is called, you must call the registerForContextMenu() method and pass in the View for which you want to have a context menu. This means each View on your screen can have a different context menu, which is appropriate as the menus are designed to be highly contextual. 
• Here we have an example of a Chronometer timer, which responds to a long click with
  a context menu:
• We will override onContextItemSelected() to Listen the Item Event Selected
  
  Download Android Context Menu :Example Code

Context Menu with ItemListener :

• We have put two Control "TextView" and "Chronometer" in following main.xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    android:id="@+id/TV01"
    />
<Chronometer android:text="Chronometer" 
 android:id="@+id/chronometer1" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" />
</LinearLayout>

• We Create Menu using XML file res/menus/menutxt.xml for TextView as follows.. 

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/M1"
     android:title="Menu 1" />
    <item android:id="@+id/M2"
     android:title="Menu 2" />
    <item android:id="@+id/M3"
     android:title="Menu 3" />
</menu>

• We Create Menu using XML file res/menus/menucm.xml for TextView as follows..

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menuStart"
     android:title="Start" />
    <item android:id="@+id/menuStop"
     android:title="Stop" />
    <item android:id="@+id/menuRestart"
     android:title="Restart" />
</menu>

• Then in the following Activity file in the method onCreateContextMenu() we have created Menu for TextView & Chronometer and Register for each Contrrol and using onContextItemSelected() we will listen the events of Chronometer ..

package com.widget;

import android.app.Activity;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.MenuItem;
import android.view.View;
import android.widget.Chronometer;
import android.widget.TextView;

public class ContextMenuXmlActivity extends Activity {
    /** Called when the activity is first created. */
 TextView tv;
    Chronometer cm;
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        cm=(Chronometer)findViewById(R.id.chronometer1);
        tv=(TextView)findViewById(R.id.TV01);
        registerForContextMenu(cm);
        registerForContextMenu(tv);
    }

 @Override
 public boolean onContextItemSelected(MenuItem item) {
  // TODO Auto-generated method stub
  switch(item.getItemId())
  {
   case R.id.menuStart:
    cm.start();
    break;
   case R.id.menuStop:
    cm.stop();
    break;
   case R.id.menuRestart:
    cm.setBase(android.os.SystemClock.elapsedRealtime());
    break;
  }
  return super.onContextItemSelected(item);
 }

 @Override
 public void onCreateContextMenu(ContextMenu menu, View v,
   ContextMenuInfo menuInfo) {
  // TODO Auto-generated method stub
  if(v.getId()==R.id.TV01)
  {
   getMenuInflater().inflate(R.menu.menutxt, menu);
  }
  if(v.getId()==R.id.chronometer1)
  {
   getMenuInflater().inflate(R.menu.menucm, menu);
   menu.setHeaderIcon(android.R.drawable.ic_media_play);
   menu.setHeaderTitle("Timer.....");
  }
  super.onCreateContextMenu(menu, v, menuInfo);
 }
    
}

• When you long click on Chronometer the following ContextMenu will be displays. 
• And you can perform "Start", "Stop" and "Restart"  the Chronometer.
•  

Android SubMenu with Example

Submenu

• Submenus are displayed as regular Menu Items that, when selected, reveal more items.
• Traditionally,submenus are displayed in a hierarchical tree layout. Android uses a different approach to simplify menu navigation for small-screen devices. Rather than a tree structure, selecting a submenu presents a single floating window that displays all of its Menu Items. 
• You can add submenus using the addSubMenu() method. It supports the same parameters as the add method used to add normal Menu Items, enabling you to specify a group, unique identifier, and text string for each submenu. You can also use the setHeaderIcon and setIcon methods to specify an iconto display in the submenu’s header bar or icon menu, respectively.

We will see an Exaple that will Display SubMenu for Background & TextColor of the Text View Whatever color you will select that will be set as Backfround and Text color respectively

• We will create menu "Text Color" and "Text Color" and add the Sub Menu to these menus. 
• Using menu/menus.xml file as follows.

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/TextColor" 
     android:title="Text Color">
     <menu >
       <item android:id="@+id/TextRed" 
        android:title="Red" />
       <item android:id="@+id/TextGreen" 
        android:title="Green" />
       <item android:id="@+id/TextBlue" 
        android:title="Blue" />
     </menu> 
    </item>
    
    <item android:id="@+id/BackColor" 
     android:title="Back Color">
     <menu >
       <item android:id="@+id/BackRed" 
        android:title="Red" />
       <item android:id="@+id/BackGreen" 
        android:title="Green" />
       <item android:id="@+id/BackBlue" 
        android:title="Blue" />
     </menu> 
    </item>
    
</menu>

• We will write the Java code as follows.

package com.widget;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

public class SubMenuXmlActivity extends Activity {
    /** Called when the activity is first created. */
    TextView tv;
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tv=(TextView)findViewById(R.id.Tv01);
    }
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // TODO Auto-generated method stub
  getMenuInflater().inflate(R.menu.menus, menu);
  
  return super.onCreateOptionsMenu(menu);
 }
 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  // TODO Auto-generated method stub
  switch(item.getItemId())
  {
  case R.id.TextRed:
   tv.setTextColor(Color.RED);
   break;
  case R.id.TextGreen:
   tv.setTextColor(Color.GREEN);
   break;
  case R.id.TextBlue:
   tv.setTextColor(Color.BLUE);
   break;
  case R.id.BackRed:
   tv.setBackgroundColor(Color.RED);
   break;
  case R.id.BackGreen:
   tv.setBackgroundColor(Color.GREEN);
   break;
  case R.id.BackBlue:
   tv.setBackgroundColor(Color.BLUE);
   break; 
  }
  return super.onOptionsItemSelected(item);
 }
 
 
}

• The OutPut will be as follows First click on Menu Button. That will display two menu as follows
  
  
•  Than suppose we select "Text Color" that show following Submenu for Text Color.
  
  
•  Suppose if we select "Red" than the Text Color of TextView Will become Red.
  
  
•  Than suppose we select "Back Color" that show following Submenu for Back Color.
  
  
•  Suppose if we select "Green" than the Background Color of TextView Will become Green.
