Example of using PopupMenu

Android 3.0(API Level 11) provide android.widget.PopupMenu class, to displays a Menu in a modal popup window anchored to a View. The popup will appear below the anchor view if there is room, or above it if there is not. If the IME is visible the popup will not overlap it until it is touched. Touching outside of the popup will dismiss it.

Example of using PopupMenu

Create a file /res/menu/popupmenu.xml to define the PopupMenu.
<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <group android:id="@+id/group_popupmenu">
      <item android:id="@+id/menu1"
          android:title="Popup menu item 1"/>
      <item android:id="@+id/menu2"
          android:title="Popup menu item 2"/>
      <item android:id="@+id/menu3"
          android:title="Popup menu item 3"/>
  </group>
</menu>
