How to remove SnapHelper from a RecyclerView

Question

I use attachToRecyclerView(RecyclerView) and it works as expected.

Question: at some point I want the same recyclerView to scroll normally, how to achieve that?

Code:

PagerSnapHelper pagerSnapHelper = new PagerSnapHelper();
pagerSnapHelper.attachToRecyclerView(recyclerView);

Answer 1

Staring from recyclerview-v7:25.1.0, is enough to call

snapHelper.attachToRecyclerView(null); 

to remove the SnapHelper

I faced the same problem. Calling

clearOnScrollListeners();
setOnFlingListener(null);

on the RecyclerView instance did the trick for me. Calling only setOnFlingListener(null); wasn't enough in my case

Answer 2

well,it's written on the SnapHelper official API:Public methods=>attachToRecyclerView:[The RecyclerView instance to which you want to add this helper or null if you want to remove SnapHelper from the current RecyclerView.] https://developer.android.com/reference/android/support/v7/widget/SnapHelper.html#attachToRecyclerView%28android.support.v7.widget.RecyclerView%29

Answer 3

If you don't want to keep the reference of SnapHelper then there is another way around as per the official documentation you can use

recyclerView.setOnFlingListener(null);

From the Android documentaion

• Attaches the {@link SnapHelper} to the provided RecyclerView, by calling
• {@link RecyclerView#setOnFlingListener(RecyclerView.OnFlingListener)}.
• You can call this method with {@code null} to detach it from the current RecyclerView.

Caution

SnapHelper.attachToRecyclerView() can throw IllegalArgumentException

• @throws IllegalArgumentException if there is already a {@link RecyclerView.OnFlingListener}
• attached to the provided {@link RecyclerView}.
