[英]an instance of type 'android.view.ViewGroup' cannot be assigned to a variable of type 'com.android.keyguard.ChallengeLayout'
如何解決這個錯誤
無法將類型為“ android.view.ViewGroup”的實例分配給類型為
com.android.keyguard.ChallengeLayout的變量
碼
ChallengeLayout challenge = mSlidingChallengeLayout != null ?
mSlidingChallengeLayout : mMultiPaneChallengeLayout;
該錯誤意味着您的布局不是ViewGroup王者。 接口[ChallengeLayout][1]將由您的ViewGroup實現，在這里，它似乎是SlidingChallengeLayout ...因此，請確保類SlidingChallengeLayout實現了ChallengeLayout
PS：ChallengeLayout不是公共API。 確保您確實需要自定義Android ROM ...
