public RecyclerViewAdapter(Context context, ArrayList list) {

    this.mData = list;
}

public class ViewHolder extends RecyclerView.ViewHolder {

    public TextView tvNama, tvSource, tvSummary;
    public ImageView img;


    public ViewHolder(View v) {
        super(v);
        tvNama = v.findViewById(R.id.name);
        tvSource = v.findViewById(R.id.oleh);
        tvSummary = v.findViewById(R.id.summary);
        img = v.findViewById(R.id.img1);

    }
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.activity_main_list, parent, false);
    ViewHolder vh = new ViewHolder(v);
    return vh;
}
// this is my viewHolder
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    holder.tvNama.setText("Nama : " + mData.get(position).getName());
    holder.tvSource.setText("" + mData.get(position).getOwner_name());
    holder.tvSummary.setText("" + mData.get(position).getSummary());

    //i don't know how to edit this
Glide
            .with(context)
            .load(mData.get(position).getImage())
            .into(holder.img);
}

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

请帮忙，我想从该网址加载图像，但它总是强制关闭。我不明白该怎么做。

这是我的模型类，我认为它有一些东西。模型: 包 com.example.projectbesar;

import java.util.ArrayList;

public class ModelBiodata {
        private String success;
        private ArrayList<Data> data;
    }

    public String getSuccess() {
            return success;
        }

        public void setSuccess(String success) {
            this.success = success;
        }

        public ArrayList<Data> getData() {
            return data;
        }

        public void setData(ArrayList<Data> data) {
            this.data = data;
        }
}

看起来您没有用于在 ModelBiodata 类中设置变量的构造函数。

您可以考虑按如下方式修改该类。

public class ModelBiodata {
    private String success;
    private ArrayList<Data> data;

    public ModelBioData() {
    }

    public void setSuccess(String success) {
        this.success = success;
    }

    public void setData(ArrayList<Data> data) {
        this.data = data;
    }

    public String getSuccess() {
        return success;
    }

    public void setSuccess(String success) {
        this.success = success;
    }

    public ArrayList<Data> getData() {
        return data;
    }

    public void setData(ArrayList<Data> data) {
        this.data = data;
    }
}

如果 Data 类没有任何 public 构造函数，则也对该类执行相同的操作，并添加 setter 来初始化该类内的私有(private)变量。

希望能解决您的问题。
