Answer 1

I think you have not properly added the facebook library :-

Right click your project ->Java build path -> Order and Export and make sure the facebook library is checked.

Also, make sure under Android dependencies > facebooksdk.jar, that you see com.facebook.widget.LoginButton.

If it's still not working, try deleting the facebook library, re-adding it, close and restart Eclipse.

尝试将xmlns:facebook="http://schemas.android.com/apk/res-auto"到RelativeLayout
