Answer 1

Option I: Using getLocationOnScreen on all Child Views inside ScrollView

1. Get instance of scroll view.

   ScrollView scrollView = findViewById(R.id.scrollViewID);

2. Type cast into ViewGroup

   ViewGroup viewGroup = (ViewGroup)scrollView;

3. Find all child views of ViewGroup ( check Android Documentation )

   Get rectangle representing location of Child View on screen by calling - getLocationOnScreen

   getLocationOnScreen will store x,y coordinates in Rect object, compare rect x,y coordinates to see if Rectangles lies within screen bounds. ( You can get screen by using getLocationOnScreen on Content View / Root View )

Option II: getGlobalVisibleRect on All child views inside ScrollView ( Quick and Easy )

1. Get all child views inside ScrollView. Call getGlobalVisibleRect on each of the child views, if it returns true, it means at-least some of portion of the child view is visible.
