关于安卓开发中menu点击问题

cyy3701608 2012-03-19 09:01:26

我在最简单的程序里面添加了两个菜单按钮，就想测试一下
代码是:
public class Activity01 extends Activity {
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
if (item.getItemId()==1) {

System.out.println("xml---->");
} else if (item.getItemId()==2) {
System.out.println("2");

}
return super.onOptionsItemSelected(item);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
menu.add(0, 1, 1, "1");
menu.add(0, 2, 2, "2");
return super.onCreateOptionsMenu(menu);
}
报的错误是
03-19 12:59:04.806: W/KeyCharacterMap(395): No keyboard for id 0
03-19 12:59:04.806: W/KeyCharacterMap(395): Using default keymap: /system/usr/keychars/qwerty.kcm.bin
03-19 12:59:06.815: W/InputManagerService(59): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@44eb8130
不知道是什么错误，网上找了一下，任然没有得到答案，求帮助啊
求具体步骤
