我在 IntentService 中运行后台任务。我在通知栏中显示进度(使用 NotificationManager),如果有人点击该通知,我想取消任务。
我通过广播服务成功实现了它。但是,我在想是否可以对 localBroadcast 做同样的事情。
如果我将“registerReceiver”更改为“LocalBroadcastManager.getInstance(this).registerReceiver”,代码将不起作用。你能告诉我为什么我不能使用带有 pendingintent 的 localbroadcast 吗?
谢谢,
目前我的代码是:
boolean isCancelled;
Context context;
NotificationManager mNotifyManager;
NotificationCompat.Builder mBuilder;
int mId = 2;
protected void onHandleIntent(Intent intent) {
isCancelled = false;
context = getApplicationContext();
IntentFilter filter = new IntentFilter();
filter.addAction("com.migrationdesk.mylibman.MyServiceClass.STOP");
registerReceiver(receiver, filter);
getNotification();
mainTask(); // THIS IS SOME BACKGROUND TASK
}
private final BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals("com.migrationdesk.mylibman.MyServiceClass.STOP")){
isCancelled = true;
}
}
};
protected void getNotification() {
Intent newintent = new Intent();
newintent.setAction("com.migrationdesk.mylibman.MyServiceClass.STOP");
PendingIntent pIntent = PendingIntent.getBroadcast(context, 0, newintent, 0);
mNotifyManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(context);
mBuilder.setContentTitle("Cover Download")
.setContentText("In progress")
.setContentIntent(pIntent)
.setSmallIcon(R.drawable.ic_launcher);
}
最佳答案
However, I was thinking is it possible to do the same with localBroadcast.
那是不可能的。 PendingIntent
仅适用于常规广播,并且管理通知栏的代码无论如何都不在您的进程中。
关于android - 具有 PendingIntent 的全局广播或本地广播,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/20908104/
