Android-RecyclerView在androidX下找不

找不到recyclerview，那就再添加下面这句：

implementation'com.android.support:recyclerview-v7:28.0.0'

如果是其他的compileSdkVersion版本

//it requires compileSdkVersion 25

compile'com.android.support:recyclerview-v7:25.1.0

'compile'com.android.support:recyclerview-v7:25.0.0'

//it requires compileSdkVersion 24

compile'com.android.support:recyclerview-v7:24.1.1'

compile'com.android.support:recyclerview-v7:24.1.0'

//it requires compileSdkVersion 23

compile'com.android.support:recyclerview-v7:23.4.0'

compile'com.android.support:recyclerview-v7:23.3.0'

compile'com.android.support:recyclerview-v7:23.2.1'

compile'com.android.support:recyclerview-v7:23.2.0'

compile'com.android.support:recyclerview-v7:23.1.1'

compile'com.android.support:recyclerview-v7:23.1.0'

compile'com.android.support:recyclerview-v7:23.0.1'

compile'com.android.support:recyclerview-v7:23.0.0'

//it requires compileSdkVersion 22

compile'com.android.support:recyclerview-v7:22.2.1'

compile'com.android.support:recyclerview-v7:22.2.0'

compile'com.android.support:recyclerview-v7:22.1.1'

compile'com.android.support:recyclerview-v7:22.1.0'

compile'com.android.support:recyclerview-v7:22.0.0'

//it requires compileSdkVersion 21

compile'com.android.support:recyclerview-v7:21.0.3'

compile'com.android.support:recyclerview-v7:21.0.2'

compile'com.android.support:recyclerview-v7:21.0.0'

或者使用

compile'com.android.support:recyclerview-v7:+'

最版本的会提示把compile修改成implementation
