Collapsingtoolbarlayout android

I decided to try to create an animated toolbar well, that is, with a picture that falls when scrolled down. I found the source code on the Internet, with two options, tested that the first, that the second, and that in the first case, that in the second, the whole thing works, but it hangs wildly, and my phone is not ancient. However, in the same VC, everything works with a bang. Here are the source codes.

The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); //noinspection SimplifiableIfStatement if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } }
