如何在android中访问Serializable对象

Question

我使用Serializable接口将用户定义的数据从一个活动发送到另一个活动。

这是我的代码：

TasksheetData[] alltasks = new TasksheetData();
Intent in=new Intent(TaskSheetList.this, TaskDetails.class);
in.putExtra("TaskSheetData", alltasks);

在其他活动中，我正在访问此对象，如：

TasksheetData tData =  (TasksheetData) getIntent().getSerializableExtra("TaskSheetData");

这是我的TasksheetData类

@SuppressWarnings("serial")
public class TasksheetData implements Serializable {

    private int TaskID;

    private int AttendantID;
    private String  AttendentName;

    private String  ReservationID;

    }
}

但是当我尝试将它强制转换为我的数据对象时，它会给出类强制转换异常。

请帮我解决这个问题？

Answer 1

您正在放入一个数组并期待一个对象。另外，请使用ArrayList serializable。{/ p>

Answer 2

不确定您的TasksheetData课程是什么，但也许您应该使用alltasks代替ParcelableArray。

您的TasksheetData数组绝对不是一个Serializable类的实例...
