java.lang.IndexOutOfBoundsException：索引：1，大小：1 onBindViewHolder

Question

大家下午好，我在 recyclerview 中创建列表时遇到了这个问题。我的 API 响应有一个列表，在该列表中有一个图像列表，我需要访问它才能获取图像 link 并将其上传到我的图像视图。

我的 API 回复：

{
"data": [
    {
        "id": "KCLSwV5",
        "title": "I wake up when i have my morning coffee",
        "description": null,
        "images": [
            {
                "id": "k47zXXl",
                "title": null,
                "link": "https://i.imgur.com/k47zXXl.jpg"
            }
        ]

    }
    ]
}

所以我这样创建了我的模型。

public class Data implements Serializable {

@SerializedName("id")
@Expose
private String id;

@SerializedName("title")
@Expose
private String title;

@SerializedName("description")
@Expose
private String description;

@SerializedName("images")
@Expose
private List<Images> images = null;


//Getters and Setters
public List<Images> getImages() { return images; }

public void setImages(List<Images> images) { this.images = images; }

日志显示我的适配器在 onBindViewHolder 方法中发生错误。

我的适配器：

public class ListAdapter extends RecyclerView.Adapter<ListAdapter.ListViewHolder> {

private Context context;
private List<Data> dataList;

public ListAdapter(Context context, List<Data> dataList) {
    this.context = context;
    this.dataList = dataList;
}

@NonNull
@Override
public ListAdapter.ListViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.list_item, viewGroup, false);
    return new ListAdapter.ListViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull ListAdapter.ListViewHolder listViewHolder, int i) {

    String image = dataList.get(i).getImages().get(i).getLink(); //LINE 39 I believe the error is here, but I don't know how to solve it.


    Glide.with(context)
            .load(image)
            .apply(new RequestOptions()
            .placeholder(R.drawable.load))
            .into(listViewHolder.imageView);
}

@Override
public int getItemCount() {
    return dataList.size();
}

public class ListViewHolder extends RecyclerView.ViewHolder {
    public ImageView imageView;

    public ListViewHolder(@NonNull View itemView) {
        super(itemView);

        imageView = itemView.findViewById(R.id.image);
    }
}
}

如果有人能帮助我，我将不胜感激。

干杯。

解析错误使用此模型，使用本网站制作模型。 Jsontopojo

  public class Example {

@SerializedName("id")
@Expose
private String id;
@SerializedName("title")
@Expose
private String title;
@SerializedName("description")
@Expose
private String description;
@SerializedName("images")
@Expose
private List<Image> images = null;

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public String getDescription() {
return description;
}

public void setDescription(String description) {
this.description = description;
}

public List<Image> getImages() {
return images;
}

public void setImages(List<Image> images) {
this.images = images;
}

}
-----------------------------------com.example.Image.java-----------------------------------

package com.example;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class Image {

@SerializedName("id")
@Expose
private String id;
@SerializedName("title")
@Expose
private Object title;
@SerializedName("link")
@Expose
private String link;

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public Object getTitle() {
return title;
}

public void setTitle(Object title) {
this.title = title;
}

public String getLink() {
return link;
}

public void setLink(String link) {
this.link = link;
}
