java.lang.ClassCastException: com.avos.avoscloud.AVObject cannot be cast to cn.com.asz.entity.LibraryItem
请问这个问题如何解决？
我让libraryITem按照文档的格式写了，代码如下：
package cn.com.asz.entity;

import com.avos.avoscloud.AVClassName;
import com.avos.avoscloud.AVObject;

/**
* Created by nijian on 2015/6/4.

@AVClassName("LibraryItem")
public class LibraryItem extends AVObject {

private String imageView;
private String text;

public LibraryItem() {
}

public LibraryItem(String imageView, String text) {
    this.imageView = imageView;
    this.text = text;
}

public String getImageView() {
    return imageView;
}

public void setImageView(String imageView) {
    this.imageView = imageView;
}

public String getText() {
    return text;
}

public void setText(String text) {
    this.text = text;
}

}
请问，这个问题如何解决？
