Window 经理动画师状态和 activity 返回堆栈

Question

我想知道这两者是否相关。

我无法在另一个 activity 之上显示对话框。我想我做的是：

开始activity拨打phone电话，
BroadcastReceiver 监听 Intent.ACTION_NEW_OUTGOING_CALL 启动 activity（带有 Intent.FLAG_ACTIVITY_NEW_TASK 标志），它将显示对话框（我们称之为 InCallActivity），
在InCallActivity的onCreate我建一个DialogFragment然后显示出来

我看到的只是com.android.dialer/com.android.incallui.InCallActivity，没有我的对话。

dumpsys window animator 说

  Window #0: WindowStateAnimator{42433660 com.android.systemui.ImageWallpaper}
  Window #1: WindowStateAnimator{428f9a20 com.google.android.googlequicksearchbox/com.google.android.launcher.GEL}
  Window #2: WindowStateAnimator{4287ae60 com.android.settings/com.android.settings.DevelopmentSettings}
  Window #3: WindowStateAnimator{42800678 com.android.settings/com.sprd.settings.SprdUsbSettings}
  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
  Window #7: WindowStateAnimator{4282de98 com.android.dialer/com.android.incallui.InCallActivity}
  Window #8: WindowStateAnimator{426e5cb0 InputMethod}
  Window #9: WindowStateAnimator{424e09b8 KeyguardScrim}
  Window #10: WindowStateAnimator{424dd0a8 Keyguard}
  Window #11: WindowStateAnimator{422c4598 StatusBar}

并且android.task.incallui总是在任务堆栈的顶部

Running activities (most recent first):
  TaskRecord{427a9cf8 #745 A=android.task.incallui U=0 sz=1}
    Run #4: ActivityRecord{423c18e8 u0 com.android.dialer/com.android.incallui.InCallActivity t745}
  TaskRecord{427d0768 #744 A=myApp U=0 sz=1}
    Run #3: ActivityRecord{42373f28 u0 myApp/.InCallActivity t744}
  TaskRecord{424b8170 #743 A=myApp U=0 sz=2}
    Run #2: ActivityRecord{422f0fb0 u0 myApp/.MainActivity t743}
  TaskRecord{4289c550 #657 A=com.sprd.settings.SprdUsbSettings U=0 sz=1}
    Run #1: ActivityRecord{41ac4b30 u0 com.android.settings/com.sprd.settings.SprdUsbSettings t657}
  TaskRecord{42778c78 #522 A=com.android.settings U=0 sz=1}
    Run #0: ActivityRecord{41a8a0b0 u0 com.android.settings/.DevelopmentSettings t522}

mResumedActivity: ActivityRecord{423c18e8 u0 com.android.dialer/com.android.incallui.InCallActivity t745}
mLastPausedActivity: ActivityRecord{42373f28 u0 myApp/.InCallActivity t744}

如何在 com.android.dialer/com.android.incallui.InCallActivity 之上显示该对话框？

Answer 1

好吧，我找到了解决方法。我没有将 activity 显示为对话框（或 activity 中的对话框），而是运行显示带有布局参数的小部件（添加新视图）的服务，例如 TYPE_SYSTEM_ALERT .
