Listview is not scrolling vertically?

Question

I have one Parent Fragment which is holding view pager.

In view pager there are two fragment called 1stFragVP and 2ndFragVP.

In 1stFragVP's layout i have Listview.

View pager is able to scroll horizontally but listview vertical scroll is not happening.

try this code:

yourlistView.setOnTouchListener(new ListView.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    int action = event.getAction();
                    switch (action) {
                        case MotionEvent.ACTION_DOWN:
                            events.
                            v.getParent().requestDisallowInterceptTouchEvent(true);
                            break;

                        case MotionEvent.ACTION_UP:
                            events.
                             v.getParent().requestDisallowInterceptTouchEvent(false);
                            break;
                    }


                    v.onTouchEvent(event);
                    return true;
                }
            });

it will disable the parent view touch management and pass the event to your listview .
