Android programming Implementation To add a menu to the application of the method _android

This article describes the Android programming implementation to add a menu to the application method. Share to everyone for your reference, specific as follows:

There are many ways to add menus, and it is generally recommended that you create menus with XML.

To establish the menu step:

Create a menu folder under Res and add an XML file inside the menu file:

<?xml version= "1.0" encoding= "Utf-8"?> <menu xmlns:android=
"http://schemas.android.com/apk/res/" Android ">
  <item android:id=" @+id/play android:title= "Play
     "
     android:visible= "true"/>
  <item android:id= "@+id/stop"
     android:title= "Stop"
     android:visible= "true"/>
</menu>

To add a menu to an application:

How do I add a defined menu when the application starts? In the Oncreateoptionsmenu () event, use the Menuinflater to add the defined menu to the program:

@Override Public
Boolean oncreateoptionsmenu (Menu menu) {
  //TODO auto-generated method stub
    Menuinflater Inflater = Getmenuinflater ();
    Inflater.inflate (R.menu.options_menu, menu);
    return true;
}

At this point, the menu has been added to the application, but there is a problem, now the menu is only displayed, and does not handle the trigger menu message, then you can use the onoptionsitemselected () event to customize message processing , The following is a menu implementation that stops and plays music:

@Override Public
Boolean onoptionsitemselected (MenuItem item) {
  //TODO auto-generated method stub
  int item_id = Item.getitemid ();
  Switch (item_id) {case
  r.id.play:
    Intent Intent = new Intent (webtestactivity.this, yypservice.class);
    StartService (intent);
    break;
  Case R.id.stop:
    this.onstop ();
    break;
  Default: Return
    false;
  }
  return true;
}

The effect of the program is as follows:

I hope this article will help you with the Android program.
