android 点击菜单旋钮没反应，window already focused,求解

android 点击菜单按钮没反应，window already focused,求解.
一个很简单的代码：
public class HelloAndroidActivity extends Activity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  TextView tv = new TextView(this);
  tv.setText("Hello Word!");
  setContentView(tv);
  }


@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0, 1, 1, "aaa");
menu.add(0, 2, 2, "bbb");
return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
System.out.print("SelectItemId------------>" + item.getItemId());
return super.onOptionsItemSelected(item);
}

}

点击菜单时logcat报警告信息，输出语句也没有打印，求各位大虾帮帮忙啊：

------解决方案--------------------

探讨

悲剧啊，原来是我的System.out语句打印的东西都不出来，用Log.d输出，就正常了。
不过还是要请教一下高手为什么用System.out打印的东西输不出来，过滤器我都配置了的。

你把最后函数换成这个，保你成功，自已研究吧，哈哈
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == 1)
System.out.println("ddaaa");
else if(item.getItemId() == 2)
System.out.println("got it");
return true;
}
