我创造，我创建了一个弹出式屏幕Android应用程序。但是，当我pressing后退按钮，弹出是没有得到关闭。

I have created a android application where I have created a popup screen. But when I am pressing the back button, popup is not getting closed.

我曾尝试与onBack pressed（）。这是行不通的。

I have tried with onBackPressed(). It is not working.

谁能告诉我该怎么做。

问候，

推荐答案

您需要做的就是调用 setBackgroundDrawable 在PopupWindow初始化后。是这样的：

What you need to do is call setBackgroundDrawable on your PopupWindow after you initialize it. Something like:

myPopup.setBackgroundDrawable(new BitmapDrawable());
