/**
* @Linkify applies to a movementMethod to the textView @LinkMovementMethod. That movement method thought it
* implements a scrolling vertically method it overrides any other scrolling method the parent has.
*
* Although touchEvent can be dispached to the parent, the specific parent ScrollView needed the whole sequence
* ACTION_DOWN , ACTION_MOVE, ACTION_UP to perform (sweep detection). So the solution to this problem is after
* applying @Linkify we need to remove the textView's scrolling method and handle the @LinkMovementMethod link
* detection action in onTouchEvent of the textView.

This works for most of the cases but disables the longpress on links. I am stuck in a same problem wherein I want to handle longpress on links and the TextView as well.
The long press on TextView is working but longpress on links is not working.

Have you tried the longpress?

And another side effect is when for a longpress is performed, it opens up the link i.e. treated as click event.
