ScrollView Inside ScrollView

Question

I Know people from Google have asked us not to put Scrollable view inside another Scrollable view but is there any official statement from them directing us not to do so?

Answer 1

childScrollView.setOnTouchListener(new View.OnTouchListener() {

      @Override
    public boolean onTouch(View v, MotionEvent event) {

        int action = event.getAction();
        switch (action) {
        case MotionEvent.ACTION_DOWN:
           // Disallow ScrollView to intercept touch events.
          v.getParent().requestDisallowInterceptTouchEvent(true);
           break;

        case MotionEvent.ACTION_UP:
            // Allow ScrollView to intercept touch events.
            v.getParent().requestDisallowInterceptTouchEvent(false);
            break;
        }

        return false;
    }
});

v.getParent() = parent scrollView.
