RecyclerView snapping example with SnapHelper

How to

If you need snapping support to start, top, end or bottom, use GravitySnapHelper.

Add this to your build.gradle:

// AndroidX
implementation 'com.github.rubensousa:gravitysnaphelper:2.0'

// Old support libraries
implementation 'com.github.rubensousa:gravitysnaphelper-compat:2.0'

Otherwise, center snapping is done with LinearSnapHelper.

Snapping center:

new LinearSnapHelper().attachToRecyclerView(recyclerView);

Snapping start with GravitySnapHelper:

startRecyclerView.setLayoutManager(new LinearLayoutManager(this,
                LinearLayoutManager.HORIZONTAL, false));
                
new GravitySnapHelper(Gravity.START).attachToRecyclerView(startRecyclerView);

Snapping top with GravitySnapHelper:

topRecyclerView.setLayoutManager(new LinearLayoutManager(this));
                
new GravitySnapHelper(Gravity.TOP).attachToRecyclerView(topRecyclerView);

If you're using nested RecyclerViews, take a look at:
