我必須註冊一個接收器,它不在同一個類中。我的意思是,我有一個服務:如何在服務中註冊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);
}
}
現在我必須要註冊像一個接收器:
registerReceiver(//thereceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
內onCreate。我該怎麼做?我認爲在//thereceiver
我必須寫MyScheduleReceiver
,但當然,如果我寫在服務裏面的onCreate它不能找到它。我能怎麼做?由於
什麼是你想怎麼辦?您有註冊通知的服務,並且在該通知中您將再次啓動該服務?其實你會發送一個意圖,但在我看來,你在'MyScheduleReceiver'中做什麼是毫無意義的。另外,'service#checkPref'在我看來並沒有正確創建Intent,因爲它沒有指向一個Activity類。 – gunar
簡而言之,就是在電池更換後出現通知。現在通知僅在清單中聲明的BOOT_COMPLETED上啓動,但是如果我想在電池更改時顯示通知,我該怎麼辦?我想我必須在java中以編程方式聲明意圖?我不能只從'BOOT_COMPLETED'改變爲'BATTERY_CHANGED' ..不能以這種方式工作。 –
