我是在我的 android 应用程序中为用户设置未来通知的新手，当服务类调用使用警报管理器设置通知的特定日期时，我没有收到 putExtra 字符串。

活动课

utility.setInternalBroadcastNotification(*DYNAMIC_FUTUREDATE*, *DYNAMIC_MESSAGE*);

实用类

public void setInternalBroadcastNotification(String eventAlertDateTime, String eventNotificationMessage) {
    try {
        if (!eventAlertDateTime.equalsIgnoreCase("") && !eventNotificationMessage.equalsIgnoreCase("")) {
            Intent myIntent = new Intent(mContext, InternalBroadcastReceiver.class);
            myIntent.putExtra("message", eventNotificationMessage);

            PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, (int) System.currentTimeMillis(), myIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            Calendar calendar = new GregorianCalendar(getDefaultLocale());
            SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", getDefaultLocale());
            Date eventAlertTime = simpleDateFormat.parse(eventAlertDateTime);
            calendar.setTime(eventAlertTime);

            AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);
            alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
        }
    } catch (Exception exception) {
        exception.printStackTrace();
    }
}

InternalBroadcastReceiver 扩展了 BroadcastReceiver

@Override
public void onReceive(Context context, Intent intent) {
    Intent intet = new Intent(context, InternalMessageHandler.class);
intet.putExtra("message", intent.getStringExtra("message"));
    context.startService(intet);
}

InternalMessageHandler 扩展服务

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);

    String message = intent.getStringExtra("message");
return START_NOT_STICKY;
}

显现

<service android:name=".util.InternalMessageHandler" />

    <receiver android:name=".util.InternalBroadcastReceiver" />

在最后的服务类中，我无法获取消息字符串。

因为消息已添加到pendingIntent广播。并且当接收者被调用时，消息还没有被传递给InternalMessageHandler.

@Override
public void onReceive(Context context, Intent intent) {
Intent intet = new Intent(context, InternalMessageHandler.class);
intet.putExtra("message", intent.getStringExtra("message"););
context.startService(intet);
}
