RecyclerView Auto Scrolling with GravitySnapHelper

[c0d3sling3r]

I use RTL horizontal recyclerview with LinearLayoutManager and set GravitySnapHelper(Gravity.END) to it. But after apply a little scroll to left, the recyclerview scrolls to left automatically without any user touches. I attached a gif following to show the problem:

I found out the problem. Because the recyclerview has a setReverseLayout(true) this happens.

Thanks for the report. I'll try to find a workaround.

Can you check version 1.5 please? It should be fixed now.

hi, i still have this problem, maybe im not using it in the correct way, i instance the class as: val SnapHelper = GravitySnapHelper(Gravity.END) (its kotlin)

then i set layout-manager as: layoutManager = GridLayoutManager(context, 1, RecyclerView.HORIZONTAL, true)

is that correct for RTL horizontal scroll?

[rubensousa]

@SetareMaghari are you using 1.5? This issue was fixed on 1.5.

If you only have a span count of 1, you should use a LinearLayoutManager instead. But it should work anyway.

[SetareMaghari]

@rubensousa yes a use 1.5. i changed it to linearlayout manager but i still have the problem... also if i change it to ltr direction there is still the problem! look at here:

its my code: recycler.layoutManager = LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false) val SnapHelper = GravitySnapHelper(Gravity.START) SnapHelper.attachToRecyclerView(recycler)

and the result:(it jumps to the first!)

also the same problem for RTL...

[SetareMaghari]

@rubensousa can you help me to solve it?

[rubensousa]

I can't reproduce this anymore on 1.5. Can you build a sample project and try to reproduce this? If so, please send it to me afterwards.

just use val snapHelper = GravitySnapHelper(if (recyclerView.layoutDirection != Gravity.END) Gravity.START else Gravity.END)

[mehdijalalifar]

if use : getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL); in your activity , you need 1)add this code in recyclerView in adapter_snap.xml android:layoutDirection="ltr"

2)snapAdapter.java set reverseLayout:true set Gravity:END
