Scroll To Position

[TasTugberk]

Hi, I have an scroll item which have edit text,which is gravity set to center, inside it. Whenever I set inputType of this edit text to something, text,number or etc. it scrolls to next item when edit text is focused. To avoid that I write an focus change listener to onBindViewHolder method of adapter;
holder.textView.setOnFocusChangeListener(new View.OnFocusChangeListener() { @Override public void onFocusChange(View view, boolean b) { //textView.setGravity(Gravity.LEFT); if(b){ holder.textView.setTextColor(getResources().getColor(R.color.TabYellow)); discreteScrollView.scrollToPosition(infiniteAdapter.getClosestPosition(position)); } else { Toast.makeText(getActivity(),"Input lose focus",Toast.LENGTH_SHORT).show(); InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(view.getWindowToken(), 0); holder.textView.setTextColor(getResources().getColor(R.color.white)); } } });

This piece of code works well in API 21,25 and 26, but it does not scroll back to current position in API 22 and 23.
