We just released ConstraintLayout 1.1.2. We recommend to update to this version. It’s available from the google maven repository:
dependencies {
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
}
This release fixes a few issues present with complex chains mixing ratio and weights.
Note: There was a packaging problem with the AndroidX release of 1.1.1 which is now fixed in 1.1.2.
