您好,我正在开发应用程序,在该应用程序中我通过后台服务设置了用户输入日期和时间的通知。现在我想在每天下午 6 点设置通知/警报,询问用户是否要添加另一个条目? 我怎样才能做到这一点?我应该使用相同的后台服务还是广播接收器? 请为此提供更好的解决方案,教程将是个好主意。 提前致谢。
最佳答案
首先如下设置报警管理器
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 18);
calendar.set(Calendar.MINUTE, 30);
calendar.set(Calendar.SECOND, 0);
Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
在此创建一个广播接收器类“AlarmReceiver” onReceive 时的通知
public class AlarmReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(context, EVentsPerform.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
context).setSmallIcon(R.drawable.applogo)
.setContentTitle("Alarm Fired")
.setContentText("Events to be Performed").setSound(alarmSound)
.setAutoCancel(true).setWhen(when)
.setContentIntent(pendingIntent)
.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
notificationManager.notify(MID, mNotifyBuilder.build());
MID++;
}
}
并在 list 文件中,为 AlarmReceiver 类注册接收器:
<receiver android:name=".AlarmReceiver"/>
通过警报管理器引发事件不需要特殊权限。
