A SnapHelper that snaps a RecyclerView to an edge.
Add this to your build.gradle:
implementation 'com.github.rubensousa:gravitysnaphelper:2.2.2'You can either create a GravitySnapHelper, or use GravitySnapRecyclerView.
If you want to use GravitySnapHelper directly, you just need to create it and attach it to your RecyclerView:
val snapHelper = GravitySnapHelper(Gravity.START)
snapHelper.attachToRecyclerView(recyclerView)If you want to use GravitySnapRecyclerView, you can use the following xml attributes for customisation:
<attr name="snapGravity" format="enum">
<attr name="snapEnabled" format="boolean" />
<attr name="snapLastItem" format="boolean" />
<attr name="snapToPadding" format="boolean" />
<attr name="snapScrollMsPerInch" format="float" />
<attr name="snapMaxFlingSizeFraction" format="float" />Example:
<com.github.rubensousa.gravitysnaphelper.GravitySnapRecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:snapGravity="start" />val snapHelper = GravitySnapHelper(Gravity.START)
snapHelper.attachToRecyclerView(recyclerView)
val snapHelper = GravitySnapHelper(Gravity.CENTER)
snapHelper.attachToRecyclerView(recyclerView)
If you use setMaxFlingSizeFraction or setMaxFlingDistance you can change the maximum fling distance allowed.
- setMaxFlingDistance or setMaxFlingSizeFraction - changes the max fling distance allowed.
- setScrollMsPerInch - changes the scroll speed.
- setGravity - changes the gravity of the SnapHelper.
- setSnapToPadding - enables snapping to padding (default is false)
- smoothScrollToPosition and scrollToPosition
- RTL support out of the box
