Get The Measures of Popup Window
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 );
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;}
