We are happy to announce the release of ConstraintLayout 2.0 beta 4.
It’s available from the google maven repository:
dependencies {
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta4'
}
or if using the android.support packages:
dependencies {
implementation 'com.android.support.constraint:constraint-layout:2.0.0-beta4'
}
Documentation is available on https://developer.android.com/reference/androidx/constraintlayout/widget/ConstraintLayout
Examples are available on https://github.com/googlesamples/android-ConstraintLayoutExamples
MotionLayout
- new attributes in Transition:
- layoutDuringTransition : let you configure how MotionLayout should react to children's requestLayouts calls during a transition. Possible values are {ignoreRequest, honorRequest}
- pathMotionArc : the path taken by elements moving will use an arc. Possible values are {startVertical | startHorizontal | flip | none }
- A default transition is now possible to define, simply by omitting the start and end ConstraintSets. That default transition will be used if no other existing transition can be found to match the current start/end states.
