popupWindow.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
popupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);

 popupWindow.setFocusable(true);
popupWindow.setTouchable(true);

  popupWindow.setTouchInterceptor(new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View v, MotionEvent event) {
                        if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
                            popupWindow.dismiss();
                            return true;
                        }
                        return false;
                    }
