StaggeredAnimationGroup

A ConstraintLayout group that allows for simple staggered animations.

Usage

For a working implementation of this library see the sample/ folder.

1. Add StaggeredAnimationGroup to your ConstraintLayout:

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:id="@+id/firstView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"> 
    
    <View
        android:id="@+id/secondView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        
    <!-- here's the group -->
    <com.bartoszlipinski.constraint.StaggeredAnimationGroup
        android:id="@+id/group"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:constraint_referenced_ids="firstView, secondView"/>

</android.support.constraint.ConstraintLayout>

2. Obtain StaggeredAnimationGroup instance from the layout:

StaggeredAnimationGroup group = findViewById(R.id.group);

2. Use proper methods to show and hide Views in your group (with ids: firstView, secondView)

group.show();
// or
group.hide();

Including In Your Project

Add a proper dependency inside your build.gradle. Like this:

dependencies {
    implementation 'com.bartoszlipinski.constraint:staggeredanimationgroup:1.0.0'
    
    // obviously, you will also need those two:
    implementation 'com.android.support.constraint:constraint-layout:1.1.0-beta1'
    implementation 'com.android.support:transition:26.1.0'
}
