android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@52d5318c is not valid; is your activity running?
你需要
Context context; //declare it as an instance variable
然后在创建
context = this; // initialize in onCreate. this refers to activity context
创建"活动"后，"活动上下文"可用。
对于地图，您可以使用DialogFragment
