我在收到每日通知時遇到了一些麻煩。沒有出現警報通知
我的應用程序獲取用戶希望提醒某事的時間,時間和分鐘。
然後我用AlarmManager
設立一個報警,此時重複,同時使用報警接收機,以創建通知。
我一直在嘗試這個小時,但無法弄清楚我做錯了什麼。
我看了一堆其他SO問題,但沒有人幫助過我。
我已經將用戶的小時和分鐘輸入存儲到日期對象get habitReminder中。
我createNotifications()
方法:
private void createNotifications() {
Log.i("Reminder at",""+habitReminder.getHours()+":"+habitReminder.getMinutes());
//Create the alarms/notifications for the user
Intent alarmIntent = new Intent(this, AlarmReceiver.class);
alarmIntent.putExtra("name", habitName);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
Log.i("createNotifications", "Alarm manager is created.");
//Set the timing of the reminder
Calendar calendar = Calendar.getInstance();
Calendar now = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, habitReminder.getHours());
calendar.set(Calendar.MINUTE, habitReminder.getMinutes());
calendar.set(Calendar.SECOND,0);
//Check to make sure time is after the current date.
if(calendar.before(now)){
calendar.add(Calendar.DATE, 1);
}
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
Log.i("createNotifications", "Alarm has been set for " +habitReminder.getHours()+":"+habitReminder.getMinutes() +" daily.");
}
我的報警接收器類:
public class AlarmReceiver extends BroadcastReceiver {
private static int id =0;
@Override
public void onReceive(Context context, Intent intent) {
String name = intent.getStringExtra("name");
String title = name + " Reminder!";
String message = "Your reminder to keep up your habit!";
long when = System.currentTimeMillis();
Intent in = new Intent(context, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context,0,in,PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager nM = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification.Builder builder = new Notification.Builder(context)
.setContentIntent(contentIntent)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.mipmap.ic_launcher)
.setAutoCancel(true)
.setWhen(when);
Notification notification = builder.build();
nM.notify(id,notification);
id++;
}
}
而且我的Android manifest
:
<receiver android:name="com.closedbracket.trackit.AlarmReceiver" android:enabled="true">
</receiver>
任何幫助真的很感激。
你可以把'Log'裏面你'的onReceive()'和檢查,這是獲得在設定的時間觸發。 –
我有一個'setExact(AlarmManagaer ...)'的例子,它適用於我,所以它可以幫助你,[創建和設置AlarmManager](https://stackoverflow.com/a/44303234/5212904),它還解釋瞭如何從另一個Activity中取消AlarmManager。然後,如果你一直到達接收者,那麼你已經完成了一半,問題是'Notification'是否被正確實現。 – ArtiomLK
