Android的 - 保存realmlist一种境界对象

Question

我有一个模型

public class Response extends RealmObject { 

     @PrimaryKey 
     private String _id; 
     private RealmList<TaskResponse> task_responses; 
     private AssignmentRecord assignmentRecord; 
     private ResponseStatistic responseStats; 
} 

现在里面，我试图挽救task_responses realmlist响应内，但未能成功，下面是相关代码：

mRealm.beginTransaction(); 
    response.setTaskResponses(taskResponses); 
    response.setAssignmentRecord(assignmentRecord); 
    response.setResponseStats(responseStatistic); 
    mRealm.commitTransaction(); 

当我放置调试这一行

response.setTaskResponses(taskResponses); 

taskResponses的大小为5，但前后执行它变成空的，realm存储一个空列表。

TaskResponse型号：

public class TaskResponse extends RealmObject { 

     @PrimaryKey 
     private String _id; 
     private String taskId; 
     private Boolean answered; 
     private String answer; 
     private TaskStatistic taskStat; 
    } 

Answer 1

您可以保存这样它会工作

Realm mRealm = Realm.getDefaultInstance(); 
    mRealm.beginTransaction(); 
    RealmList<TaskResponse> taskResponseslist = new RealmList(); 
    taskResponseslist.addAll(taskResponses); 
    response.setTaskResponses(taskResponseslist); 
    response.setAssignmentRecord(assignmentRecord); 
    response.setResponseStats(responseStatistic); 
    mRealm.commitTransaction(); 
    mRealm.close();
