[Android]Could not resolve dependencies recyclerview-v7:28.0.0-alpha1.

報錯：
Could not resolve com.android.support:recyclerview-v7:28.0.0-alpha1.

改正方法如下：
將
implementation 'com.android.support:recyclerview-v7:28.0.0-alpha1'

改為

implementation 'com.android.support:recyclerview-v7:26.+'

root cause：compileSdkVersion 26
