Recyclerview not scrolling to end when keyboard opens

You can catch keyboard up changes using recyclerview.addOnLayoutChangeListener(). If bottom is smaller than oldBottom then keyboard is in up state.

if ( bottom < oldBottom) { 
   recyclerview.postDelayed(new Runnable() { 
       @Override 
       public void run() {
           recyclerview.smoothScrollToPosition(bottomPosition); 
       }
    }, 100);
}

Add this your activity or fragment:

    if (Build.VERSION.SDK_INT >= 11) {
        recyclerView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v,
                    int left, int top, int right, int bottom,
                    int oldLeft, int oldTop, int oldRight, int oldBottom) {
                if (bottom < oldBottom) {
                    recyclerView.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            recyclerView.smoothScrollToPosition(
                                    recyclerView.getAdapter().getItemCount() - 1);
                        }
                    }, 100);
                }
            }
        });
    }
