Answer 1

I have faced the same problem and I solved it using the approach mentioned here. It is used to detect whether soft keyboard is open or not and if it is open, just call the smoothScrollToPosition() method.

A much simpler solution is to give your activity's root view a known ID, say '@+id/activityRoot', hook a GlobalLayoutListener into the ViewTreeObserver, and from there calculate the size diff between your activity's view root and the window size:

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
    int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
    if (heightDiff > 100) { 
        recyclerView.smoothScrollToPosition(myAdapter.getItemCount() - 1);
    }
 }
});

Easy!
