Menu in Android

Hello Friends, Today i am going to post different example of Android menu.
Android provides a standard XML format to define menu items
create an XML file inside your project's res/menu/ directory and build the menu.

1. OptionMenu Example:

Res/menu/option_menu.xml

<?xml version="1.0" encoding="utf-8"?>

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

    <item

        android:id="@+id/Opt1"

        android:icon="@drawable/ic_launcher"

        android:title="Opt1"/>

    <item

        android:id="@+id/Opt2"

        android:icon="@drawable/ic_launcher"

        android:title="Opt2"/>

    <item

        android:id="@+id/Opt3"

        android:icon="@drawable/ic_launcher"

        android:title="Opt3"/>

</menu>

OptionnsMenuActivity.class

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 OptionsMenuActivity extends Activity

{     

       @Override

       protected void onCreate(Bundle savedInstanceState)

       {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.activity_main);

       }

       @Override

       public boolean onCreateOptionsMenu(Menu menu)

       {     

              MenuInflater inflater = getMenuInflater();

              inflater.inflate(R.menu.option_menu, menu);

              return true;

       }

       public boolean onOptionsItemSelected(MenuItem item)

       {

              switch (item.getItemId())

              {

              case R.id.Opt1:

                     Toast.makeText(this, "You have chosen the Opt1 menu option",

                                  Toast.LENGTH_SHORT).show();

                     return true;

              case R.id.Opt2:

                     Toast.makeText(this, "You have chosen the Opt2 menu option",

                                  Toast.LENGTH_SHORT).show();

                     return true;

              case R.id.Opt3:

                     Toast.makeText(this, "You have chosen the Opt3 menu option",

                                  Toast.LENGTH_SHORT).show();

                     return true;

              default:

                     return super.onOptionsItemSelected(item);

              }

       }

}

2. Custom OptionMenu Example:
we can also create custom menu for Android Application.here is the example of custom menu.

custom_menu.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:gravity="bottom"

    android:orientation="horizontal" >

    <Button

        android:id="@+id/Btn1"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:background="@drawable/ic_launcher"

       />

    <Button

        android:id="@+id/Btn2"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:background="@drawable/ic_launcher"

       />

    <Button

        android:id="@+id/Btn3"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:background="@drawable/ic_launcher"

       />

    <Button

        android:id="@+id/Btn4"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:background="@drawable/ic_launcher"

       />

</LinearLayout>

CustomOptionsActivity.class

import android.app.Activity;

import android.app.AlertDialog;

import android.content.Context;

import android.os.Bundle;

import android.view.KeyEvent;

import android.view.View;

public class CustomOptionsActivity extends Activity

{

       MenuDialog customMenuDialog;

       @Override

       public void onCreate(Bundle savedInstanceState)

       {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.activity_main);

             

       }

       private class MenuDialog extends AlertDialog

       {

              public MenuDialog(Context context)

              {

                     super(context);

                     View cus_menu = getLayoutInflater().inflate(R.layout.custom_menu,null);                

                     setView(cus_menu);

                    

              }

              @Override

              public boolean onKeyUp(int keyCode, KeyEvent event)

              {

                     if (keyCode == KeyEvent.KEYCODE_MENU)

                     {

                           dismiss();

                           return true;

                     }

                     return super.onKeyUp(keyCode, event);

              }

       }

       @Override

       public boolean onKeyUp(int keyCode, KeyEvent event)

       {

              if (keyCode == KeyEvent.KEYCODE_MENU)

              {

                     if (customMenuDialog == null)

                     {

                           customMenuDialog = new MenuDialog(this);

                     }

                     customMenuDialog.show();

                     return true;

              }

              return super.onKeyUp(keyCode, event);

       }     

      

}

3. Context Menu Example:

context_menu.xml

<?xml version="1.0" encoding="utf-8"?>

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

    <item

        android:id="@+id/edit"

        android:title="Edit"/>

    <item

        android:title="Save"/>

    <item

        android:id="@+id/delete"

        android:title="Delete"/>

    <item

        android:id="@+id/view"

        android:title="View"/>

</menu>

ContextMenuActivity.class

import android.app.Activity;

import android.os.Bundle;

import android.view.ContextMenu;

import android.view.ContextMenu.ContextMenuInfo;

import android.view.MenuInflater;

import android.view.MenuItem;

import android.view.View;

import android.widget.AdapterView.AdapterContextMenuInfo;

import android.widget.Button;

import android.widget.Toast;

public class ContextMenuActivity extends Activity

{

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState)

    {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

       

        Button button=(Button)findViewById(R.id.button1);

        registerForContextMenu(button); 

    }

    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)

    {

      super.onCreateContextMenu(menu, v, menuInfo);

      MenuInflater inflater = getMenuInflater();

      inflater.inflate(R.menu.context_menu, menu);

    }

  

    public boolean onContextItemSelected(MenuItem item)

    {

      AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();

    

      switch(item.getItemId())

      {

      case R.id.edit:

            Toast.makeText(this, "You have chosen the Edit",Toast.LENGTH_SHORT).show();
