Question

我正在尝试创建一个发送多个预定警报的应用，通过根据特定时间（不是时间间隔，但是时间）显示一天。

我已经实现了在每个意图中触发通知的AlarmReceiver.class，但问题是我没有收到任何通知。我试图在Log方法中显示onReceiver()，但邮件尚未显示，因此尚未发出警报。

这是setAlarm()函数，用于设置实例化Calendar的小时和时间：

public void setAlarm()
{
    SharedPreferences pref = this.getSharedPreferences("NOTIFICATION_CODE", Context.MODE_PRIVATE);

    String mName = NameFld.getText().toString();
    String mFormat = FormatSpn.getSelectedItem().toString();

    Date date = new Date();
    Calendar calendar = Calendar.getInstance();
    Calendar current = Calendar.getInstance();

    current.setTime(date);
    calendar.setTime(date);

    calendar.set(Calendar.HOUR_OF_DAY, picker_hour);
    calendar.set(Calendar.MINUTE, picker_minute);
    calendar.set(Calendar.SECOND, 0);


    if(current.before(calendar))
    {
        calendar.add(Calendar.DATE, 1);
    }

    medName = mName;
    medFormat = mFormat;

    int _reqCode = pref.getInt("reqCode", -1);
    Intent intent = new Intent(this, AlarmReceiver.class);

    PendingIntent pIntent = PendingIntent.getBroadcast(this, _reqCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    AlarmManager aManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    aManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pIntent);

    editor = pref.edit();
    editor.putInt("reqCode", ++_reqCode);
    editor.commit();

}

要设置时间，我实施了TimePickerDialog，我将小时和分钟值存储到picker_hour和picker_minute。由于我必须发送多个闹钟，因此我使用SharedPreferences存储reqCode，然后在每次发送时识别PendingIntent。

这是AlarmReceiver.class，它为每个收到的意图发出通知。每个通知都通过reqCode：

的PendingIntent标识

public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {

    String[] data = AddMedicine.getData();

    SharedPreferences pref = context.getSharedPreferences("NOTIFICATION_CODE", context.MODE_PRIVATE);
    int reqCode = pref.getInt("reqCode", -1);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
    builder.setAutoCancel(true);
    builder.setTicker("It's pill time!");
    builder.setContentTitle(data[0]);
    builder.setContentText(data[1]);
    builder.setSmallIcon(R.drawable.ic_launcher);

    Notification notification = builder.build();
    NotificationManager nManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
    nManager.notify(reqCode, notification);
    Log.i("NOTIFICATION", "FIRED!");
}}

P.S。每次用户创建警报时都会设置警报，以便通过reqCode安排它们。

那么，有谁知道如何根据时间发送多个警报？提前谢谢！
