TextView:shadowDx/Dy/Radius in dip?
If it’s not specified then the unit is always in px.
android:shadowDx, shadowRadius 后面的值是dip还是px还是sp ?
not dp,it’s px,用不同尺寸的手机或模拟器试试便知1

1 | Consider replacing `android:layout_alignParentRight` with `android:layout_alignParentEnd="true"` to better support right-to-left layouts |
1 | Buttons in button bars should be borderless; use `style="?android:attr/buttonBarButtonStyle"` (and `?android:attr/buttonBarStyle` on the parent) |
Button 和 其父视图 都需要加上对应的属性1

现象：com.caiyi.youle.databinding.ActivityCameraRecordVideoLayoutBinding 这个包，可以跳转过去。
解决方法：是布局文件问题。
