我想知道这两者是否相关。
我在另一个活动的顶部显示对话框时遇到问题。 我认为我做的是：
BroadcastReceiver的Intent.ACTION_NEW_OUTGOING_CALL启动活动（带Intent.FLAG_ACTIVITY_NEW_TASK标志），该活动将显示对话框（让我们称之为InCallActivity），onCreate的{{1}}我构建了一个InCallActivity然后显示它。我看到的只是DialogFragment而没有我的对话。

Window #4: WindowStateAnimator{428939d8 myApp/myApp.MainActivity}
Window #5: WindowStateAnimator{42835be0 myApp/myApp.InCallActivity} <- that's probably the activity itself
Window #6: WindowStateAnimator{4283f518 myApp/myApp.InCallActivity} <- that's probably the dialog

答案 0 :(得分：0)
好吧，我找到了解决方法。 我没有将活动显示为对话框（或活动中的对话框），而是运行一个服务，该服务使用LayoutParams显示小部件（添加新视图），例如TYPE_SYSTEM_ALERT。
