Simples Menus in Android

How to add simple menu in android?

Now lets Create a simple menu item in android.

There are 3 types of menu in android.
1.Options menu
2.Context menu
3.Popup menu

First we'll discuss about options menu

1.MainActivity.java

package com.sri.menus;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.Toast;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

// TODO Auto-generated method stub

switch (item.getItemId()) {

case R.id.m1:

Toast.makeText(getApplicationContext(), "menu 1",

Toast.LENGTH_SHORT).show();

break;

case R.id.m2:

Toast.makeText(getApplicationContext(), "menu 2",

Toast.LENGTH_SHORT).show();

default:

break;

}

return super.onOptionsItemSelected(item);

}

}

2.activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="Displaying Menu" />

</RelativeLayout>

3. Check in res/menu folder the main.xml

in that

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item

        android:id="@+id/action_settings"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="@string/action_settings"/>

    <item

        android:id="@+id/m1"

        android:showAsAction="ifRoom"

        android:title="menu 1"/>

    <item

        android:id="@+id/m2"

        android:showAsAction="ifRoom"

        android:title="menu 2"/>

</menu>

4. In main.xml, the android:showAsAction="ifRoom" is written to show it on the action bar and have the more priority.

android:showAsAction="never" is used to hide in the menu and show's on more button.

5.That's it now run it.
