Question

I am able to create an OptionMenu, see code below. But in my program the problem is that I have to write logic in every activity.

If I have an application with 10 activities. I have to write code for the menu everywhere.

I want to create a single menu for the whole application. No matter where i am. If I click on the Hardware Menu key then I must be able to get to the Menu. How do I create this type of universal Menu?

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;

public class SimpleOptionMenu extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.animation_test);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.icon:
            Toast.makeText(this, "You pressed the icon!", Toast.LENGTH_LONG)
                    .show();
            break;
        case R.id.text:
            Toast.makeText(this, "You pressed the text!", Toast.LENGTH_LONG)
                    .show();
            break;
        case R.id.icontext:
            Toast.makeText(this, "You pressed the icon and text!",
                    Toast.LENGTH_LONG).show();
            break;
        }
        return true;
    }

}

animation_test.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <Button  
        android:id="@+id/btn_ani"
        android:layout_alignParentTop="true"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="Click to start animation"/>

</RelativeLayout>

Simply create a new Activity with the onOptionsSelected method and extend this created Activity.

class OptionsActivity extends Activity {

    public boolean onOptionsItemSelected(MenuItem item) {
       ...
    }

}

class SimpleOptionsMenu extends OptionsActivity {
   ...
}
