Question

我正在尝试创建一个能够设置多个警报的警报应用程序，但是我需要向onReceive发送一个自定义数组列表，问题是它会抛出...

java.lang.RuntimeException: Parcel: unable to marshal value id:7, type:kitchen, wkt:LINESTRING (11.6999998092651 8.40000057220459, 11.4499998092651 9.85000038146973, 10.6500005722046 10, 8.5 9.19999980926514, 9.15000057220459 8.90000057220459, 10.9499998092651 9.25, 11.6999998092651 8.40000057220459), centerX:10.400001,centerY:9.266667, owner:null, keyword:Kitchen, subMap:0

问题似乎是由未决的Intent引起的。

private void  startAlarm(ArrayList<Long> aTime) {
    AlarmManager[] alarmManagers = new AlarmManager[20];
    ArrayList<PendingIntent> intentArrayList = new ArrayList<>();

    for (int i = 0 ; i<aTime.size(); i++)
    {
        Intent intent = new Intent(this, AlarmReceiver.class);
        intent.putExtra("LOC", arrayListRooms);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this,i,intent,PendingIntent.FLAG_UPDATE_CURRENT);
        alarmManagers[i] = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManagers[i].set(AlarmManager.RTC_WAKEUP, aTime.get(i),pendingIntent);

        intentArrayList.add(pendingIntent);
    }

}

这是自动生成的读取宗地，除了arrayListRooms（我的自定义arraylist从方法返回）之外。

protected dbAlarmManager(Parcel in) {
    super(robotCallback,robotListenCallback);
    location = in.createStringArrayList();
    time = in.createStringArrayList();
    sTime = in.readString();
    sLoc = in.readString();
    sTitle = in.readString();
    sFirstRoom = in.readString();
    sSecondRoom = in.readString();
    aTitle = in.createStringArrayList();
    intent = in.readParcelable(Intent.class.getClassLoader());
    hour = in.createIntArray();
    min = in.createIntArray();
    arrayListRooms =  in.createTypedArrayList((Creator<RoomInfo>) arrayListRooms);
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeStringList(location);
    dest.writeStringList(time);
    dest.writeString(sTime);
    dest.writeString(sLoc);
    dest.writeString(sTitle);
    dest.writeString(sFirstRoom);
    dest.writeString(sSecondRoom);
    dest.writeStringList(aTitle);
    dest.writeParcelable(intent, flags);
    dest.writeIntArray(hour);
    dest.writeIntArray(min);
    dest.writeList(arrayListRooms);

}

我还已经拥有所有宗地变量的getter和setter方法。

我该怎么办？预先感谢。

在Parcelable中使用自定义PendingIntent对象时，经常会遇到这样的问题。本质上，系统将取消包裹并重新包裹您的extras捆绑包，但是由于它无权访问您的类或类加载器，因此数据将丢失。
