Android Menu Example

    ANDROID MENU EXAMPLE

(This example includes basic menu example)

    We will create a menu button for the Android 2.2 Froyo in this example. You can also develop for the Android 2.2 Froyo and you can use this menu at Android 2.3 and lower versions of  the android properly.

    After the android 3.0, the menu button is deprecated but many people using android now also have lower versions.

1 ) Context menu : When you click on a link as long press. You will see some choices on the screen this is the context menu.

2 ) Pop up menu : If you see in a faded screen as list this will be the pop up menu.

    DEFINING A MENU IN XML

    You should define your menu items at the xml as developer-android.com says. You can also create your list in your java code. You can then get this xml as Menu object with inflating.

    You can use your res/menu folders for this xml. Create a new xml named as customize_menu.xml

    Example xml is such below :

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

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

      <item

        android:id="@+id/menu_settings1"

        android:title="@string/menu_settings"

        android:checkable="true"

        android:menuCategory="container"

        android:titleCondensed="@string/app_name"

        />

   

        <item

        android:id="@+id/menu_settings2"

        android:title="@string/menu_settings"

        android:checkable="true"

        android:menuCategory="container"

        android:titleCondensed="@string/app_name"

        />

        <item

        android:id="@+id/menu_settings3"

        android:title="@string/menu_settings"

        android:checkable="true"

        android:menuCategory="container"

        android:titleCondensed="@string/app_name"

        />

</menu>

And also in your activity class you can code as

@Override

        public boolean onCreateOptionsMenu(Menu menu) {

               

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

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

                return true;

        }

    For more, you can change your list order with the attribute of

   android:orderInCategory="Number"

    for example if you define your android:orderInCategory in one item as 100 it will be in the 100^th order.

    You can also change your contents of the menu items programmatically. For example changing the all of the menu items titles that helped me http://stackoverflow.com/questions/6150080/set-a-menu-item-as-checked-from-code

After you run this application you must get this screen as in Picture 1

Picture 1

package com.example.menuexample;

import android.os.Bundle;

import android.app.Activity;

import android.view.LayoutInflater;

import android.view.Menu;

import android.view.MenuInflater;

import android.view.MenuItem;

import android.widget.TextView;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

TextView tV = (TextView) findViewById(R.id.can);

tV.setText("Menu Example");

}

@Override

public boolean onPrepareOptionsMenu(Menu menu) {

   super.onPrepareOptionsMenu(menu);

   menu.findItem(R.id.menu_settings1).setTitleCondensed("menu1");

   menu.findItem(R.id.menu_settings2).setTitleCondensed("menu2");

   menu.findItem(R.id.menu_settings3).setTitleCondensed("menu3");

   return true;

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

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

return true;

}

}

This is the java codes related with menu. onPrepareOptionsMenu gives you the opportunity to manipulate the id based resources. You can not manipulate the menu in onCreateOptionsMenu because inflater has not been finished yet so you would crash with the null pointers.

Also there is super tutorial that is suitable for advance customization
