在View Pager中不显示图像，我已经从JSON获取了图像URL，但是Image Loader显示图像时出现了一些错误。
模型：
public class ZoomimageModel {
private int id;
private String imageUrl;
public void ZoomimageModel(String imageUrl) {
this.imageUrl=imageUrl;
}
public void setId(int id) {
this.id = id;
}
public int getId() {
return id;
}
public String getImageUrl() {
return imageUrl;
}
public void setImageUrl(String imageUrl) {
this.imageUrl = imageUrl;
}
}
查看寻呼机适配器：

我在Image Loader中出错，任何人可以解决我的问题。预先感谢。
slideShowImages.get(position)
它返回一个ZoomimageModel不是imageUrl
