Question

我有以下方法将三个值保存到intent中，该方法附加到创建的警报。

public static Boolean setUniqueAlarm(Long alarmId, String occurenceTime, Context context) {
        Boolean saveResult = null;
        try {
            DateTime dt = TimeHelper.getDateTimeObject(occurenceTime);
            Logger.d("Year: " + dt.getYear() + ", month: " + dt.getYear() + ", day: " + dt.getDayOfMonth() + ", hour: " + dt.getHourOfDay() + ", minute: " + dt.getMinuteOfHour());
            Logger.d("Occurrence time to save: "+occurenceTime);
            AlarmManager alarmManager = (AlarmManager) context.getApplicationContext().getSystemService(Context.ALARM_SERVICE);
            Intent alarmIntent = new Intent(context, AlarmBroadcastReceiver.class);
            // Pass the intent type and other additional values into bundle
            Bundle bundle = new Bundle();
            bundle.putString(Constants.Global.ALARM_TYPE, Constants.Global.ALARM_TYPE_UNIQUE);
            bundle.putString(Constants.Global.ALARM_OCCURRENCE_TIME, "123456");
            bundle.putLong(Constants.Global.ALARM_UNIQUE_ID, alarmId);
            alarmIntent.putExtras(bundle);
            PendingIntent pendingAlarmIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
            alarmManager.set(AlarmManager.RTC_WAKEUP, dt.getMillis(), pendingAlarmIntent);
            saveResult = true;
        } catch (Exception e) {
            Logger.e(e.getMessage());
            saveResult = false;
        }
        return saveResult;
    }

在接收器中我有以下代码：

@Override
    public void onReceive(Context context, Intent intent) {
        try {
            Logger.d("ALARM RECEIVED!!!");
            PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
            // Device battery life will be significantly affected by the use of this API.
            PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "TAG");
            // Acquire the lock
            wl.acquire();
            //Release the lock
            wl.release();
            // Get the intent type (or stored variables)
            Bundle extras = intent.getExtras();
            mAlarmType = extras.getString(Constants.Global.ALARM_TYPE);
            mAlarmId = extras.getLong(Constants.Global.ALARM_UNIQUE_ID, 0);
            mOccurenceTime = extras.getString(Constants.Global.ALARM_OCCURRENCE_TIME, "nothing");
            triggerActionBasedOnTheAlarmType(mAlarmType, mAlarmId, mOccurenceTime, context);
        } catch (Exception e) {
            TrackingEventLogHelper.logException(e, Constants.Global.EXCEPTION,
                    Constants.ExceptionMessage.EXC_CANNOT_PROCESS_RECEIVED_ALARM, true);
        }
    }

问题是变量 mOccurenceTime 始终为null，rsp。 “无”。

我试图从意图和Bundle获取值，但仍然没有成功。物品的捆绑数量是否有限？

如何以正确的方式获得价值 mOccurenceTime ？

非常感谢您的任何建议。

这是正确的方法 - 指定一个标志！

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, uniqueRequestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);

而不是：

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, uniqueRequestCode, intent, 0);

因为标志的0会让你头疼

这可能是一个很受欢迎的问题，因为Google的示例代码在警报中忽略了Extra。

解决方案：

Android cannot pass intent extras though AlarmManager

Android：无法保存和读取Bundle中的所有值
