View Pagerで画像が表示されないため、JSONから画像URLを取得しましたが、Image Loaderで画像を表示する際にエラーが発生しました。View Pagesで画像スライダの画像がアンドロイドに表示されない
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;
}
}

Image Loaderでエラーが発生しました。いずれかの問題を解決するのに役立ちます。 ありがとうございます。
