回收站视图项中的 ScrollView 不滚动

Question

I have MetarialCardView which has a certain height inside of RecyclerView's list item and I have a scrollView inside this MetarialCardView. I want to scroll by putting a long text in the ScrollView, but it is not scrolling. Besides that typically MaterialCardView is clickable, but with scrollView, it is losing its clickability too.

I appreciate any help you can provide.

Answer 1

Try using NestedScrollview instead ScrollView in xml and below code in java file

    recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
        @Override
        public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
            int action = e.getAction();
            switch (action) {
            case MotionEvent.ACTION_MOVE:
                rv.getParent().requestDisallowInterceptTouchEvent(true);
                break;
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
});

Try this one. I also removed the icon from scroll view if you want to scroll that to just put it inside the scrollview.

for click i think you can set click listener on itemView or just give id to cardview and set click listener on that.
