import android.app.Activity;

import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;

public class DeviceOptionsMenuActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);
    }
   
    public boolean onCreateOptionsMenu(Menu menu) {
       
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.my_options_menu, menu);
        return true;
    }
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.about:
        startActivity(new Intent(this, About.class));
        return true;
        case R.id.help:
        startActivity(new Intent(this, Help.class));
        return true;
        default:

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class About extends Activity {
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.about);

import android.os.Bundle;
import android.view.Window;

public class Help extends Activity {
   

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.help);
    }
}
 

Dont change main.xml keep it as it is..we dont need that one for our example.

Now Create about.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
   
    android:orientation="vertical" >

   
        <RelativeLayout
            android:id="@+id/relativeLayout1"
            android:layout_width="fill_parent"
            android:layout_height="280dp"
            android:layout_weight="0.19" >

            <TextView
                android:id="@+id/textView1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:layout_marginTop="139dp"
                android:textSize="9pt"
                android:text="This Application is sponsored by"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#717C40" />

            <TextView
                android:id="@+id/textView2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView1"
                android:layout_below="@+id/textView1"
                android:textSize="8pt"
                android:text="Ronak Pandya"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#717C40" />

            <TextView
                android:id="@+id/textView3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView2"
                android:layout_below="@+id/textView2"
                android:textSize="8pt"
                android:text="You are free to use it."
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#717C40" />

            <TextView
                android:id="@+id/textView4"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView3"
                android:layout_centerVertical="true"
                android:textSize="8pt"
                android:text="Please contact us at,"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#772020" />

            <TextView
                android:id="@+id/textView5"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView4"
                android:layout_below="@+id/textView4"
                android:textSize="8pt"
                android:text="support@support.com"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#0F53FF" />
        </RelativeLayout>
 
</LinearLayout>

help.xml (Write whatever content you want to write....)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
   

</LinearLayout>

Now Create a dir called menu--> in that create xml file called my_options_menu.xml in

i.e res/menu/my_options_menu.xml

my_options_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/about"
android:title="About" />
<item android:id="@+id/help"
android:title="Help" />
</menu>

Finally Add Both activities Help and about.java to AndroidMenifiest.xml file 

Run it...
