Recyclerview not scrolling to end when keyboard opens

Issue

I am using recylerview in my application and whenever new element is added to recyclerview, it scrolls to last element by using

recyclerView.scrollToPosition(adapter.getCount());

But, whenever keyboard opens(because of editTextView), it resizes the view and recyclerview gets smaller, but couldn't scroll to last element.

android:windowSoftInputMode="adjustResize"

I even tried to used the following code to scroll to last element, but it didn't work

editTextView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus){
                recyclerView.scrollToPosition(chatAdapter.getItemCount());
            }
        }
    });

I can try adjustPan to shift the pan up, but it is hiding my toolbar. Please suggest any way to rectify the issue.

Solution

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);
}
