RecyclerView's height not adjusted when the AppBarLayout is expanded

Question

The code for initializing the RecyclerView

private void initRecyclerView() {
    layoutManager = new GridLayoutManager(this, spanCount);
    mRecyclerRV.setLayoutManager(layoutManager);
    mRecyclerRV.addItemDecoration(new GridSpacingItemDecoration(spanCount, (int) (TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, spaceInDp, getResources().getDisplayMetrics()) + 1), false));
    mRecyclerRV.setNestedScrollingEnabled(false);
    mRecyclerRV.setAdapter(mAdapter);
    mRecyclerRV.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
            if (!recyclerView.canScrollVertically(-1)
                    && RecyclerView.SCROLL_STATE_SETTLING == newState
                    && mScrollVerticalDirection
                    && mIsAppBarCollapsed) {
                mAppBarLayout.setExpanded(true);
            }
        }

        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            mScrollVerticalDirection = (dy < 0);
        }
    });

    mRecyclerRV.postDelayed(new Runnable() {
        @Override
        public void run() {
            RecyclerView.ViewHolder holder = mRecyclerRV.findViewHolderForAdapterPosition(1);
            if (null != holder) {
                holder.itemView.performClick();
            }
        }
    }, 1000);
}

The layout file is here, and uses CoordinatorLayout

</android.support.design.widget.CoordinatorLayout>

When the AppBarLayout is collapsed the RecyclerView scroll happens correctly.

But when the AppBarLayout is expanded, the height of the RecyclerView does not adjust and the scrolling appears abnormal

Answer 1

No ways to get it. But resize the recycler view when the app bar is expand or gonna collapse.
