show one Recyclerview item at a time - Android

Question

My Recyclerview item occupies the whole screen height and width. I wish to implement a custom scroll inside the Recyclerview such that it scrolls only one item at a time ( similar to News In Shorts app ).

Thanks in advance!!

Answer 1

You need to add just two below Lines

RecylerView mRecylerView = (RecylerView).findViewById(R.id.mRecylerView)
SnapHelper mSnapHelper = new PagerSnapHelper();
mSnapHelper.attachToRecyclerView(mRecylerView);

SnapHelper can be used to snap the child to any imaginary point or any pixel on the screen

Answer 2

Try this code

parentScrollView.setOnTouchListener(new View.OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {

        findViewById(R.id.childScrollView).getParent().requestDisallowInterceptTouchEvent(false);
        return false;
    }
});
childScrollView.setOnTouchListener(new View.OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {

        // Disallow the touch request for parent scroll on touch of
        // child view
        v.getParent().requestDisallowInterceptTouchEvent(true);
        return false;
    }
});
