我在onDestroy 方法里也dismiss 了diaolog   当前Activity里面有一个dialog 但是我关的时候 dialog没有关闭成功   是否要先判断 当前activity是否活着？
如果没有活着就关闭dismiss掉 dialog？请教！！！

Answer 1

在onDestroy()方法这样写,if(dialog!=null && dialog.isShowing(){dialog.dismiss()}

Answer 2

这个方法是在你的Activity里面有弹出的Dialog,而在Dialog没有被关闭的时候 你就退出了Dialog,所以就会出现此错误。
   最后还要提醒一下LZ，在Dialog内部要使用Context时，一定要用当前Activity的Context,不能使用getApplicationContext，切记呀。

Answer 3

当你显示的弹出框的上下文环境已经消失,再去操作弹出框就会弹出这个错误，一般我们的上下文环境就是activity,所以像楼上所说的确定你的activity是否是活动的
