public void showPopup(Context c,          


        

Answer 1

Another way:

/**
 * @return Point object which:<br>
 * point.x : contains width<br>
 * point.y : contains height
 */
public static Point getViewSize(View view) {
    Point size = new Point();
    view.post(new Runnable() {
        @Override
        public void run() {
            size.set(view.getWidth(), view.getHeight());
        }
    });
    return size;
}

Answer 2

You won't get the height or width of the view, which hasn't been drawn on the screen.

pupLayout.getWidth() // this will give you 0

You need to get the width like this

int width = MeasureSpec.makeMeasureSpec(0, MeasureSpec. UNSPECIFIED);

Use it like this

View pupLayout = inflater.inflate(R.layout.linearlayout_popup, base);
pupLayout.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), 
            MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));

int x = location[0] - (int) ((pupLayout.getMeasuredWidth() - v.getWidth()) / 2 );
