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);
 }
}
