在警报应用程序中,用户可以设置无限量的警报吗? 我在我的项目中处理警报选项,我意识到它的工作只有一次。如果我想要能够发出许多警报,应该如何使用Threads或IntentFilter,或者其他什么呢?
public class AlarmReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
String title = intent.getStringExtra("Title");
NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
Intent myIntent = new Intent();
System.out.println("Title: " + title);
switch (title){
case "Weight":
myIntent = new Intent(context, WeightActivity.class);
break;
case "Measure":
myIntent = new Intent(context, measurActivity.class);
break;
case "Pr":
myIntent = new Intent(context, PrsActivity.class);
break;
case "Macros":
myIntent = new Intent(context, DietActivity.class);
break;
}
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.dumbbell)
.setContentTitle("Tracker")
.setContentText(title)
.setAutoCancel(true);
notificationManager.notify(1, builder.build());
}
}
答案 0 :(得分:0)
这就是 requestCodes 。
的原因请注意 requestCode , 您只需在设置警报时为PendingIntent使用不同的请求代码。
public setMyAlarm(int requestCode){
AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
PendingIntent alarmIntent = PendingIntent.getBroadcast(context, requestCode, intent, 0);
alarmMgr.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() +
60 * 1000, alarmIntent);
}
由于requestCode的类型是int,因此应该足以设置大量的警报。
另外,对于取消闹钟,你必须提到具有相同requestCode的Pending intent,你曾经设置闹钟。
请不要误解你的通知的待定内容。
