Android RecyclerView smooth scroll to view that's animating their height

Question

I have a RecyclerView with Expandable Child Views, when the child ViewGroup is clicked it inflates an amount of views animating the ViewGroup height from 0 to the measured viewg

Answer 1

My solution was to constant check for view bottom within applyTransformation method, and compare it with RecyclerView height, if the bottom get higher than the RV height, i scroll by the diff values:

final int bottom = collapsible_content.getBottom();
final int listViewHeight = mRecyclerView.getHeight();
if (bottom > listViewHeight) {
    final int top = collapsible_content.getTop();
    if (top > 0) {
        mRecyclerView.smoothScrollBy(0, Math.min(bottom - listViewHeight + mRecyclerView.getPaddingBottom(), top));
    }
}

The trick was to use Math.min to get the view top, so it don't scroll up making the top not visible.

Solution based on ListViewAnimations

Answer 2

Add an animationlistener and start the scrolling of the recyclerview after the expanding animation is finished.
