Answer 1

I have this code: PopupWindow below a specific view (Gravity End) for all sdk version.

        // display the popup[![enter image description here][1]][1]
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            mPopupWindow.showAsDropDown(v, 0, 0, Gravity.END);
        } else {
            mPopupWindow.showAsDropDown(v, v.getWidth() - mPopupWindow.getWidth(), 0);
        }

Here View v is ImageButton Calendar.
