Dialog中弹出PopupWindow

今天要做一个记住用户登陆的账号的功能，用户在切换账号的时候可以选择之前登陆过的账号，直接登陆，

在网上找了一下有了实现方法：

还是先贴图：

现在显示是没问题了，可是隐藏却成了问题，我点击EditText 右边的箭头可以弹出PopupWindow，

可是再点击该按钮，和点击PopupWindow以外的区域，点击Back键都隐藏不了，必须点击PopupWindow中listview的Item的时候它才会隐藏，

之前在Activity中是可以的，为什么在Dialogz中却不行呢。

mPopup.setOutsideTouchable(true);这句话就是让点击PopupWindow外面的时候让它隐藏的，但是在Dialog中加了却也隐藏不了。

再到网上找了一下，我尝试的加了一下两句话：

        mPopup.setAnimationStyle(android.R.style.Animation_Dialog);
        mPopup.setBackgroundDrawable(new BitmapDrawable());

这下可以实现点击PopupWindow以外的区域也让它隐藏了。

再贴一下图片：

贴一下代码：
