Android recyclerView findViewHolderForAdapterPosition returns null

Question

I want to click an item in recyclerView programmatically, I found a way do that:

recyclerView.findViewHolderForAdapterPosition(0).itemView.performClick();
         


        

Answer 1

you can do this:

postAndNotifyAdapter(new Handler(),mRecyclerView);



protected void postAndNotifyAdapter(final Handler handler, final RecyclerView recyclerView) {
    handler.post(new Runnable() {
        @Override
        public void run() {
            if ( recyclerView.findViewHolderForLayoutPosition(0)!=null) {
                // This will call first item by calling "performClick()" of view.
                recyclerView.findViewHolderForLayoutPosition(0).itemView.performClick();
            } else {
                //   
                postAndNotifyAdapter(handler, recyclerView);
            }
        }
    });
}
