Strikethrough text ListView cannot find symbol method

Question

I'm doing a to-do list and I wanted add a strikethrough effect after double tapping the ListView but it gave me an error which says the following.

Cannot find symbol listView.setPaintFlags(listView.getPaintFlags() _ Paint.STRIKE_THRU_TEXT_FLAG)

How Can I solve it?

listView.setOnTouchListener(new View.OnTouchListener() {
    private GestureDetector gd = new GestureDetector(MainActivity.this,new GestureDetector.SimpleOnGestureListener() {
        public boolean onDoubleTap(MotionEvent e) {
            ListView listView = (ListView) findViewById(R.id.listView);
            listView.setPaintFlags(listView.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
            return true;
        }
    });
        @Override
        public boolean onTouch(View view, MotionEvent event) {
            return gd.onTouchEvent(event);
        }
    });
}

I do not think the ListView has the method which provides the strikethrough feature on its items. I think the TextView inside an item of your ListView has the attribute which should work like the following.

TextView tv = (TextView) v.findViewById(android.R.id.text1);
tv.setPaintFlags(tv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

You might also consider implementing your custom adapter to get the reference of the TextView and strikethrough the view using the code above.
