Android--menu菜单

一个简单的menu菜单示例：

 public class MenuDemo extends Activity {

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

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

    }

 @Override

 public boolean onCreateOptionsMenu(Menu menu) {

  super.onCreateOptionsMenu(menu);

  menu.add(0,0,0,"老婆");

  menu.add(0,1,0,"老公");

  menu.add(0,2,0,"菜单一");

  menu.add(0,3,0,"菜单二");

  menu.add(0,4,0,"菜单三");

  return true;

 }

 @Override

 public boolean onOptionsItemSelected(MenuItem item) {

  super.onOptionsItemSelected(item);

  TextView view = (TextView) findViewById(R.id.text_view);

  switch (item.getItemId()) {

  case 0:

   view.setText("这是"+item.getTitle());

   break;

  case 1:

   view.setText("这是"+item.getTitle());

   break;

  default:

            view.setText("这是老婆的菜单，嘿嘿。。。");

  break;

  }

  return false;

 }

 @Override

 public boolean onPrepareOptionsMenu(Menu menu) {

  return super.onPrepareOptionsMenu(menu);

 }

}
