public class MenuTest extends Activity {
private TextView textView;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        textView=(TextView)findViewById(R.id.textView);
    }
    public boolean onCreateOptionsMenu(Menu menu) {
     menu.add(0,0,0,"About");
     menu.add(0, 1, 1, "OK");
     return super.onCreateOptionsMenu(menu);
    }
    public boolean onOptionsItemsSelected(MenuItem item) {
     super.onOptionsItemSelected(item);
     switch(item.getItemId()) {
     case 0:
     textView.setText("you are selected about");
     Toast.makeText(MenuTest.this, "you are selected about", Toast.LENGTH_LONG).show();break;
     case 1:
     textView.setText("you are selected OK");
     Toast.makeText(MenuTest.this, "this is OK", Toast.LENGTH_SHORT).show();break;
     }
     return true;
    }
}

代码在上面  是一个Menu的Demo  不知道哪出错了点菜单没有Toast出来 Test也没有变化
