PopupWindow 的showAsDropDown 7.0以上无效

1.重写popupWindow 的showAsDropDown()方法:

@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);
 

2.初始化popupWindow时候高度不要MATCH_PARENT

   int[] location = new int[2];
   view.getLocationOnScreen(location);//view是在xx控件下方的xx
   int y = location[1];
   int popHeight = ScreenUtils.getScreenHeight(activity) - y;

 CustomPopupWindow myPop=new CustomPopupWindow(contentView, LinearLayoutCompat.LayoutParams.MATCH_PARENT, popHeight);

这样子7.0以上的就适配好了
