创建一个类，继承PopupWindow
public class Solve7PopupWindow
extends PopupWindow {
public Solve7PopupWindow(View mMenuView
, int matchParent
, int matchParent1) {
super(mMenuView
, matchParent
,matchParent1)
;
}
@Override
public void showAsDropDown(View anchor) {
if (Build.VERSION.
SDK_INT ==
24) {
Rect rect =
new Rect()
;
anchor.getGlobalVisibleRect(rect)
;
int h = anchor.getResources().getDisplayMetrics().
heightPixels - rect.
bottom;
setHeight(h)
;
}
super.showAsDropDown(anchor)
;
}
}
在new出来即可使用 centerView是你自己想要将popupWindow显示的在这个view的下面
mMenuPopupWindow =
new Solve7PopupWindow(
mMenuView, LinearLayout.LayoutParams.
MATCH_PARENT, LinearLayout.LayoutParams.
MATCH_PARENT)
;
mMenuPopupWindow.showAsDropDown(centerView)
;;
