android xml 文件中 showAsAction出错

[shidangche]

Should use app:showAsAction with the appcompat library with xmlns:app="http://schemas.android.com/apk/res-auto" less... (Ctrl+F1)
When using the appcompat library, menu resources should refer to the showAsAction in the app: namespace, not the android: namespace.

Similarly, when not using the appcompat library, you should be using the android:showAsAction attribute. 这个应该咋解决
求大神
