Android service Android AlarmManager将额外的活动传递给服务
我尝试了很多链接,但不管我的额外内容是什么,都是空的。首先,我有一个活动(MainActivity),它将使用服务(NotifyService)设置通知。我可以在适当的时间获得服务并显示通知。然而,传递字符串似乎是一个问题 在MainActivity onCreate()中,我有: 在我的NotifyService onCreate中,我有:Android service Android AlarmManager将额外的活动传递给服务,android-service,android-notifications,android-pendingintent,android-alarms,Android Service,Android Notifications,Android Pendingintent,Android Alarms,我尝试了很多链接,但不管我的额外内容是什么,都是空的。首先,我有一个活动(MainActivity),它将使用服务(NotifyService)设置通知。我可以在适当的时间获得服务并显示通知。然而,传递字符串似乎是一个问题 在MainActivity onCreate()中,我有: 在我的NotifyService onCreate中,我有: Intent myIntent = new Intent(this, NotifyService.class); //this is what I w

Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Notification notification = new NotificationCompat.Builder(this)
.setContentText(content)
.setContentTitle(title)

主要是我一直在学习本教程:
我还查看了以下链接:
我试过很多悬挂着旗帜的东西,但还是不走运。我看到它是通过意图和服务完成的,但没有任何未完成的意图
非常感谢事实证明,在创建时使用它,我必须使用onstart命令。代码如下:
@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Toast.makeText(this, "Starting..", Toast.LENGTH_SHORT).show();
Log.d("0",intent.getStringExtra("newtitle"));
title = intent.getStringExtra("newtitle");
content = intent.getStringExtra("newcontent");
Intent myintent = new Intent(this.getApplication(), MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,myintent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Action action = new NotificationCompat.Action.Builder(
R.drawable.basketball, getString(R.string.wearTitle), pendingIntent
).build();
Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Notification notification = new NotificationCompat.Builder(this)
.setContentText(content)
.setContentTitle(title)
.setSmallIcon(R.drawable.basketball)
.setSound(sound)
.extend(new NotificationCompat.WearableExtender().addAction(action))
.build();
NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(this);
notificationManagerCompat.notify(001, notification);
return PendingIntent.FLAG_UPDATE_CURRENT; // or whatever your flag
}
来自:它说我不能接受自己的答案。我试过道歉
