在某个控件下面显示弹窗

private void showPopupWindow(View view){        //加载布局        View inflate = LayoutInflater.from(getContext()).inflate(R.layout.popupwindow_credit_add_screen, null);        //更改背景颜色        inflate.setBackgroundColor(getContext().getResources().getColor(R.color.white));        PopupWindow mPopupWindow = new PopupWindow(inflate);        TextView tvAddCustomer = inflate.findViewById(R.id.tv_add_customer);        TextView tvAdvancedScreen = inflate.findViewById(R.id.tv_advanced_screen);        //必须设置宽和高        mPopupWindow.setWidth(270);        mPopupWindow.setHeight(170);        //点击其他地方隐藏,false为无反应        mPopupWindow.setFocusable(true);        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {            //对他进行便宜            mPopupWindow.showAsDropDown(view,-135,20,Gravity.BOTTOM);        }        //对popupWindow进行显示        mPopupWindow.update();    }

View传入的是控件,要显示在某个控件下面
