これは私のアダプタクラスです。私はサービスから得たjsonからのイメージを解析できません。サービスからリサイクラビューへのjsonの画像を解析できません
RecyclerViewAdapter.class
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
Context context;
List<GetDataAdapter> getDataAdapter;
ImageView imgPost;
public RecyclerViewAdapter(List<GetDataAdapter> getDataAdapter, Context context){
super();
this.getDataAdapter = getDataAdapter;
this.context = context;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_items, parent, false);
ViewHolder viewHolder = new ViewHolder(v);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
GetDataAdapter getDataAdapter1 = getDataAdapter.get(position);
holder.NameTextView.setText(getDataAdapter1.getName());
holder.SubjectTextView.setText(getDataAdapter1.getSubject());
}
@Override
public int getItemCount() {
return getDataAdapter.size();
}
class ViewHolder extends RecyclerView.ViewHolder{
public TextView NameTextView;
public TextView SubjectTextView;
ImageView imgPost;
public ViewHolder(View itemView) {
super(itemView);

、これが私のモデルクラスです。
GetDataAdapter.class
public class GetDataAdapter {
private String name;

this.imageUrl = imageUrl;

public String getName() {
return name;

public String getSubject() {
return subject;
}
public String getImageUrl() {
return imageUrl;
