在视图页面中没有在andorid中显示图像滑块的图像

在View Pager中没有显示图像，我从JSON获取了图像URL，但是Image Loader显示图像时出现了一些错误。

MODEL：

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中遇到错误，任何一个帮助解决我的问题。 提前谢谢。

1 个答案:

答案 0 :(得分：1)

actions: {
  toggle (title, event) {
    // TODO: use title 
    let element = Ember.$(event.target);
    element.toggleClass("active");

    return false;
  }
}

它返回slideShowImages.get(position) 而不是imageUrl
