Recyclerview - Overlap items bottom to top

Question

I have set the negative margin for items like this:-

ItemDecoration.java

public class ItemDecorator extends RecyclerView.ItemDecorat         


        

Answer 1

As of 2020 there is new interface ChildDrawingOrderCallback. It defines the order of drawing elements in recycler view. Can be used like so:

class BackwardsDrawingOrderCallback : RecyclerView.ChildDrawingOrderCallback {
    override fun onGetChildDrawingOrder(childCount: Int, i: Int) = childCount - i - 1
}

And then

recyclerView.setChildDrawingOrderCallback(BackwardsDrawingOrderCallback())

So there is no need to set neither reverse order nor stack from end anymore.

Answer 2

Try this way and render your recycler view in reverse direction.

LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setReverseLayout(true);
        layoutManager.setStackFromEnd(true);
        recyclerView.setLayoutManager(layoutManager);

Here is the working example GitHub Link

Answer 3

Try overriding this method.

@Override
public int getItemViewType(int position) {
    return super.getItemViewType(position);
}
