android - 如何在广播接收器 Android Kotlin 中处理多个警报

Question

我的锻炼应用程序允许用户创建多个通知警报来提示他们锻炼。我正在使用 TimePickerDialog 来设置警报。我正在使用捆绑包将警报的详细信息添加到 AlarmReceivers Intent。在 StackO 上对此进行研究后，我认为我必须使用具有不同请求代码的不同待处理意图才能产生多个警报。

我的问题是我如何在 AlarmReceiver 中知道哪个待处理的意图导致了 onReceive？我可以使用待处理意图的请求代码来确定它是哪一个吗？在意图包中有一个 id 并没有帮助，因为它可能包含两个警报附加项。

如果您能解释这应该如何工作，请提前致谢......

class TimePickerFragment : DialogFragment(), TimePickerDialog.OnTimeSetListener {

lateinit var alarmManager: AlarmManager
val intent = Intent(activity, AlarmReceiver::class.java)
val bundle = Bundle()

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {

    // use the current time as default values for the picker
    val c = Calendar.getInstance()
    val hour = c.get(Calendar.HOUR_OF_DAY)
    val minute = c.get(Calendar.MINUTE)

    // create a new instance of the TimePicker dialogue and return it
    return TimePickerDialog(getActivity(), this, hour, minute,
            DateFormat.is24HourFormat(getActivity())
            )
override fun onTimeSet(view: TimePicker, hourOfDay: Int, minute: Int) {

    val mTag = tag
    if (mTag == "time1") {

        // add alarm to the intent bundle
        bundle.putString("Alarm1", "This is the ${hourOfDay}:${minute} alert")
        intent.putExtras(bundle)
        setAlarm(hourOfDay,minute,intent, 1) //request code 1
    }

   if (mTag == "time2") {
        // add alarm to the intent bundle
        bundle.putString("Alarm2", "This is the ${hourOfDay}:${minute} alert")
        intent.putExtras(bundle)
        setAlarm(hourOfDay,minute,intent, 2) //request code 2
    }
}

fun setAlarm(hourOfDay: Int, minute: Int, intent: Intent, requestCode: Int) {

    alarmManager = activity.getSystemService(Context.ALARM_SERVICE) as AlarmManager
    val pendingIntent = PendingIntent.getBroadcast(this.activity, requestCode, intent,PendingIntent.FLAG_UPDATE_CURRENT)

    val calendar = Calendar.getInstance()
    calendar.set(Calendar.HOUR_OF_DAY, hourOfDay)
    calendar.set(Calendar.MINUTE, minute)
    calendar.set(Calendar.SECOND, 0)
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.timeInMillis, AlarmManager.INTERVAL_DAY, pendingIntent)
}

在 AlarmReceiver 类中：

class AlarmReceiver : BroadcastReceiver() 

{override fun onReceive(context: Context, intent: Intent) {

        val intent = Intent(context, AlarmReceiver::class.java)
        intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP

        val pendingIntent = val pendingIntent = PendingIntent.getBroadcast(context, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT) 
// HOW TO TEST WHICH PENDING INTENT THIS IS?
