Question

我正在尝试从下面的片段类开始一个Activity。

List.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                ItemDetail Item = DetailItem.get(position - 1);

                Intent intent = new Intent(getActivity(),
                        ComplateDetailActivity.class);
                intent.putExtra("KEY", Item);
                startActivity(intent);
            }
        });

编辑：

ItemDetail Class

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

    public float ispoints;
    public String fullDescription;

    public ItemDetail() {

    }
    @SuppressLint("SimpleDateFormat")
    public ItemDetail(ItemsDetail item , float rating , float ispoints)
    {

        this.ImageUrl = item.ImageUrl;
        this.Name = item.Name;
        this.UrlKey = item.UrlKey;
        this.DateCreated = item.DateCreated;
        try{ this.dateCreated = this.dateFormat.parse(item.DateCreated); } catch (Exception e){}
        this.rating = rating;
        this.ispoints = ispoints;
    }

}

它在3.0以上的设备上工作正常但在2.3.6崩溃。请告诉我我在这里做错了什么我也试过getActivity.startActivity(intent);。下面是logcat完整输出

EDITE 2：

这是ItemsDetail Class。

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

    public String Name;
    public String ImageUrl;
    public String DateCreated;
    public Date dateCreated;
    public DateFormat dateFormat;

    public ItemsDetail() {
        dateFormat = new SimpleDateFormat("dd-MM-yyyy");
    }

    public ItemsDetail(String title, String detail) {
        this.Name = title;
        this.Detail = detail;
    }

}

Answer 1

Android 2.3中存在DecimalFormatSymbols序列化的错误。您可以看到说明here。如果您需要解决方法，请删除使用DecimalFormatSymbols的字段（例如SimpleDateFormat等）。

<强> UPD：

我不确定，但尝试将SimpleDateFormat dateFormat字段声明为static final。
或者您可以删除SimpleDateFormat dateFormat字段并在构造函数中使用局部变量而不是此字段：

public ItemDetail(ItemsDetail item , float rating , float ispoints) {
    this.ImageUrl = item.ImageUrl;
    this.Name = item.Name;
    this.UrlKey = item.UrlKey;
    this.DateCreated = item.DateCreated;
    SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy"); // change to your format
    try {
        this.dateCreated = format.parse(item.DateCreated);
    } catch (Exception e) {
        e.printStackTrace();
    }
    this.rating = rating;
    this.ispoints = ispoints;
}

Answer 2

这是Android错误，请参阅此https://code.google.com/p/android/issues/detail?id=14495
