我必须注册一个接收器,它不在同一个类中。我的意思是,我有一个服务:如何在服务中注册Receiver?
service.java
public class service extends Service {
NotificationManager mNotificationManager;
@Override
public IBinder onBind(Intent intent) {
// Not used
return null;
}
@Override
public void onCreate() {
super.onCreate();
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
checkPref();
}
@Override
public void onDestroy() {
super.onDestroy();
}
private void checkPref() {
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(service.this);
notificationBuilder.setContentTitle("Title");
notificationBuilder.setContentText("Context");
notificationBuilder.setTicker("TickerText");
notificationBuilder.setWhen(System.currentTimeMillis());
notificationBuilder.setSmallIcon(R.drawable.ic_stat_icon);
Intent notificationIntent = new Intent(this, service.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notificationBuilder.setContentIntent(contentIntent);
notificationBuilder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE);
mNotificationManager.notify(1, notificationBuilder.build());
}
}
和MyScheduleReceiver.java
public class MyScheduleReceiver extends BroadcastReceiver {
// Restart service every 30 min
private static final long REPEAT_TIME = 30 * 1000 * 4;// 1800000 ;
@Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, service.class);
context.startService(service);
}
}
现在我必须要注册像一个接收器:
registerReceiver(//thereceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
内onCreate。我该怎么做?我认为在//thereceiver
我必须写MyScheduleReceiver
,但当然,如果我写在服务里面的onCreate它不能找到它。我能怎么做?由于
什么是你想怎么办?您有注册通知的服务,并且在该通知中您将再次启动该服务?其实你会发送一个意图,但在我看来,你在'MyScheduleReceiver'中做什么是毫无意义的。另外,'service#checkPref'在我看来并没有正确创建Intent,因为它没有指向一个Activity类。 – gunar
简而言之,就是在电池更换后出现通知。现在通知仅在清单中声明的BOOT_COMPLETED上启动,但是如果我想在电池更改时显示通知,我该怎么办?我想我必须在java中以编程方式声明意图?我不能只从'BOOT_COMPLETED'改变为'BATTERY_CHANGED' ..不能以这种方式工作。 –
