Creating Option Menus and Context menu in android

first you can create menuEx project, just like helloword .

Then create main.xml look like this.

--------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="@+id/ListView01" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<WebView android:id="@+id/_web" android:layout_width="fill_parent"
android:layout_height="fill_parent" />

</LinearLayout>
-----------------------------------

----------------------------------------------------------------------------

Now create mainmenu and contextmenu.xml file respectively

-------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/facebook" android:title="Facebook" android:icon="@drawable/facebook" />
<item android:id="@+id/twitter" android:title="Twitter" android:icon="@drawable/twitter" />
<item android:id="@+id/google" android:title="Google Plus" android:icon="@drawable/gooogle" />
<item android:id="@+id/linkedin" android:title="LinkedIn" android:icon="@drawable/linkedin" />
<item android:id="@+id/digg" android:title="Digg " android:icon="@drawable/digg" />
<item android:id="@+id/myspace" android:title="Myspace" android:icon="@drawable/myspace" />
</menu>

-----------------------------------------------------------------

<?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:id="@+id/delete" android:title="Delete" />
<item android:id="@+id/copy" android:title="Copy" />
<item android:id="@+id/paste" android:title="Paste" />
</menu>
