An Android library providing a custom CoordinatorLayout Behavior that gives AppBarLayout a springy, bouncy scroll effect. It also includes a TabScrimHelper for animating TabLayout colors alongside CollapsingToolbarLayout and optional realtime blur integration.

Use cases

• add spring bounce effect to AppBarLayout scrolling in Android
• animate TabLayout color with collapsing toolbar
• apply realtime blur to collapsing app bar
• customize CoordinatorLayout behavior for app bar
• make Android app bar scroll feel elastic

When to choose

• you want a spring/overscroll effect on AppBarLayout without reimplementing Behavior internals
• you use AndroidX or support design libraries and need a drop-in layout_behavior
• you want coordinated blur or tab color animation with app bar offset

When to avoid

• you use Jetpack Compose instead of View-based CoordinatorLayout
• you need a maintained library with active support or a clear license file
• your project no longer uses support design/AndroidX AppBarLayout
