Android-如何在片段上启动前台服务? [英] Android - how to start foreground service on fragment?

问题描述

我有一个关于在片段上启动前台服务的问题.

I have a question about starting foreground service on fragment.

Intent intent = new Intent(this, MainActivity.class);  
PendingIntent pendingIndent = PendingIntent.getActivity(this, 1, intent, 0);  
Notification mNotification = new Notification(R.drawable.ic_music, msg, System.currentTimeMillis());  
mNotification.setLatestEventInfo(this, title, msg, pendingIndent);  
mNotification.flags = mNotification.flags|Notification.FLAG_ONGOING_EVENT;  
startForeground(1000, mNotification);

↑我知道这段代码可以在Activity上启动前台服务.

↑ I know this code makes start foreground service on Activity.

所以我更改了一些用于片段的代码

so I changed some code for use on fragment

Intent intent = new Intent(getActivity(), xxx.class);  
PendingIntent pendingIndent = PendingIntent.getActivity(getActivity(), 1, intent, 0);  
Notification noti = new Notification(R.drawable.ic_xxx, "xx", System.currentTimeMillis());  
noti.setLatestEventInfo(getActivity(), "title", "xx", pendingIndent);  
noti.flags = noti.flags|Notification.FLAG_ONGOING_EVENT;  
getActivity().startForeground(1000, noti); 

我对此有疑问:

getActivity().startForeground(1000, noti);

getActivity()没有startForeground方法，我想在片段上启动前台服务.

getActivity() doesn't have startForeground method and I want to start foreground service on fragment.

我该怎么办?

推荐答案

在服务的onStartCommand()方法中尝试以下操作:

Try this in the onStartCommand() method of your service:

startForeground(NOTIFICATION_ID, new Notification());

可能是您需要返回START_STICKY来保持服务运行，直到您调用selfStop().

It might be that you need to return a START_STICKY that keeps the Service running until you call selfStop().

干杯！
