我正在尝试打开 mainActivity
当用户单击我的通知中的按钮时,该应用仅在后台运行,而使用服务。单击按钮时,这些行是在 service
类中触发的:
Intent openApp = new Intent(this, MainActivity.class);
openApp.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(openApp);
我已经检查了它,并触发了行,因此对按钮的单击,活动没有任何问题
不会打开。
有什么建议吗?为什么这对我不起作用?如何使它起作用?
编辑
我被要求提供更多代码,因此在我的 onstartcommand()
中,我的 service
在其 intent oint intent >,我调用 killService()
方法(杀死 service
)启动 mainActivity
并执行其他事情:
if (action != null && action.equals(ACTION_STOP_SERVICE)) {
killService();
}
设置 Notification
s按钮,我使用此代码:
Intent stopActionIntent = new Intent(this, TimerService.class);
stopActionIntent.setAction(ACTION_STOP_SERVICE);
PendingIntent stopActionPendingIntent = PendingIntent.getService(this, 1, stopActionIntent, PendingIntent.FLAG_IMMUTABLE);
timerNotificationBuilder.addAction(R.drawable.stop, "Stop", stopActionPendingIntent);
正如我所说,该按钮已经对用户单击它做出反应,因此这不是问题。
I'm trying to open the MainActivity
when the user clicks a button in my notification, while the app is only running in the background with a service. When the button is clicked, these lines are triggered in the Service
class:
Intent openApp = new Intent(this, MainActivity.class);
openApp.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(openApp);
I've checked it, and the lines are triggered, so there's no problem in reacting to the button's click, the Activity
won't open though.
Any suggestions? Why isn't this working for me and how can I make it work?
Edit
I was asked for some more code, so in my onStartCommand()
inside my Service
, if it starts with a stop-action within its intent
, I call the killService()
method, which kills the Service
, starts the MainActivity
and do some other stuff:
if (action != null && action.equals(ACTION_STOP_SERVICE)) {
killService();
}
To set the Notification
s button, I use this code:
Intent stopActionIntent = new Intent(this, TimerService.class);
stopActionIntent.setAction(ACTION_STOP_SERVICE);
PendingIntent stopActionPendingIntent = PendingIntent.getService(this, 1, stopActionIntent, PendingIntent.FLAG_IMMUTABLE);
timerNotificationBuilder.addAction(R.drawable.stop, "Stop", stopActionPendingIntent);
And as I said, the button already reacts to the user clicking on it, so that's not the problem.

您可以尝试在
broadcastreceiver
中接收单击,然后从那里打开活动。screateNotificationalactionbutton
方法是:stopwatchnotificationAcceAcceReceiver
的类,使其范围abroadcastreceiver
。这是该类的代码:您还需要在这样的清单中注册该接收器:
mainActivity.ServiceIntent
是一个看起来像这样的公共静态变量:此意图仅用于以这样的启动开始服务:
或者您可以尝试简单的方法:

另一个解决方案在这里。再次。您需要参考我的 repo ,因为我对文件进行了更改以进行更改以进行更改完成您的任务。 In the service class, refer to
与往常一样,您可以查看app 的结果。
我希望代码能够完成您的工作。
You can try to receive the click in a
BroadcastReceiver
and then open activity from there.Where the
createNotificationActionButton
method is this:StopwatchNotificationActionReceiver
and make it extent aBroadcastReceiver
. This is the code for that class:Also you need to register that receiver in your manifest like this:
MainActivity.serviceIntent
is a public static variable which looks like this:And this intent is only used to start the service like this:
Or you can try the simple method:

Another solution is here. Again. You need to refer to my repo as I have made changes to the files in order to complete your task. In the service class, refer to this method. There, I start the activity if the action is reset(r). Or else, it opens the broadcast receiver. Then, in the activity, I receive that extra in the
onResume()
method. If the reset button is not clicked, it opens the Receiver class.And as always, you can view the result of the app from here.
I hope that code will do your work.
我找到了!参见这个答案。
该答案表明启用
screanoverlay
设置,因为从Android 10开始,然后您才能通过调用我使用过的行来从后台打开活动。为了使它起作用,您必须通过
subtest.xml
>:然后,用户必须通过其他应用程序启用
显示
设置。我搜索了一个选项,使用户更容易地进入此设置,并找到此答案。
该答案给出了将用户重定向到其他应用程序设置的
显示的代码
,然后我用通知的内容(文本)指导用户有关如何启用设置。
设置启用后,我在工作前使用的行
。
没有完全解决
上述工作的整个配置,但前提是该应用没有被杀死。
如果该应用被杀死,我尝试了上面列出的方法,则该应用程序加入了最近的应用程序列表,但不会打开并显示。
解决此问题的解决方案将被视为答案,而不是这个问题。
I found it! See this answer.
This answer suggests enabling
ScreeanOverlay
settings because as of Android 10 and later you can no longer open an activity from the background just by calling the lines I've used.To make it work, you'd have to add this permission through your
Manifest.xml
:And then the user would have to enable the
Display over other apps
setting.I searched for an option to get the user to this setting more easily and found this answer.
This answer gives a code that redirects the user to the
Display over other apps
settingand then I guide the user with the notification's content (text) on how to enable the setting.
Once the setting is enabled, The lines I've used before work.\
So, problem solved?
Not Completely Solved
this whole configuration described above works, but only if the app is not killed.
If the app was killed and I try the method listed above, the app joins the recent apps list, but won't open and show up.
A solution that solves this issue as well will be accepted as an answer instead of this one.
