Allow scrolling EditText and swiping ViewPager

问题

I have an EditText (vertically scrollable) inside one of the fragments in a ViewPager (horizontally swipable).

By default, touch events inside the EditText can swipe the ViewPager but not scroll the EditText. By using the code below (which I don't really understand), touch events inside the EditText can scroll the EditText but not swipe the ViewPager:

editText.setOnTouchListener(new View.OnTouchListener()
{
    @Override
    public boolean onTouch(View v, MotionEvent event)
    {
        v.getParent().requestDisallowInterceptTouchEvent(! ((event.getAction() & MotionEvent.ACTION_MASK) == MotionEvent.ACTION_UP));
        return false;
    }
});

How can I simultaneously allow swiping of the ViewPager and scrolling of the EditText?

You can handle this according to the solution given here.

pager.setOnTouchListener(new View.OnTouchListener() 
{
       public boolean onTouch(View p_v, MotionEvent p_event) 
        {
               editText.getParent().requestDisallowInterceptTouchEvent(false);
           //  We will have to follow above for all scrollable contents
           return false;
        }
});

For the EditText, you will have to add this snippet.

editText.setOnTouchListener(new View.OnTouchListener() 
{
      public boolean onTouch(View p_v, MotionEvent p_event)
       {
          // this will disallow the touch request for parent scroll on touch of child view
           p_v.getParent().requestDisallowInterceptTouchEvent(true);
           return false;
       }
});

Hope it helps...
