我想在ACTION_BATTERY_LOW
時創建一個簡單的通知..我想要的是當電池電量低出現時在狀態欄中啓動一個通知。我已經試過這樣: 在OnCreate如何在ACTION_BATTERY_LOW時在通知欄中創建通知?
this.registerReceiver(this.batteryLowNotifi, new IntentFilter(Intent.ACTION_BATTERY_LOW));
然後:
private void checkPref(){
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
TutorialNotification.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, TutorialNotification.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(SIMPLE_NOTIFICATION_ID,
notificationBuilder.build());
}
private BroadcastReceiver batteryInfoReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
checkPref(intent);
}
}
但沒有發生。任何幫助?謝謝
的reciver和服務你應該登記在清單中reciver和啓動服務,並應該使用該服務來撰寫通知 –
在我的清單中已經註冊了接收器但沒有任何內容。 –
然後啓動一個服務來啓動接收器的通知 –
