Creating a Simple Menu

In this post, I show how to create a simple Menu for your device.

Create a sub folder "menu" in "res" folder in your project. Then create a new xml file in your menu folder with the name "menu.xml".

menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:id="@+id/item1" android:title="New"></item>
    <item android:id="@+id/item2" android:title="Save"></item>
    <item android:id="@+id/item3" android:title="Delete"></item>

 </menu>

MenuActivity.java


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


// onCreateOptionsMenu() method initalize the contents of Activity's standard options menu.

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater=getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }
//onOptionsItemSelected() method is called whenever an item in our options menu is selected.
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch(item.getItemId()) //getItemId returns the id for this menu item.
        {
        case R.id.item1:
            Toast.makeText(this, "You pressed New", Toast.LENGTH_LONG).show();
            break;
        case R.id.item2:
            Toast.makeText(this, "You pressed Save", Toast.LENGTH_LONG).show();
            break;
        case R.id.item3:
            Toast.makeText(this, "You pressed Delete", Toast.LENGTH_LONG).show();
            break;
        }
        return true;
    }
     
}

Run your project and you will see the output as follows.
