Question

我尝试在Recyclerview中显示文字。因此我将JsonData解析为ArrayList＆gt; 我得到这个内容后，我调用以下方法：

 private void loadprevEvents() {
    for (HashMap<String, String> data :datalist){
        items_for_preview.addString(data.get("names"));
        items_for_preview.addString("imageurl");
    }
   Customlist adapter = new Customlist_upcoming_events(items_for_preview,getApplicationContext());

}

不幸的是，这是我的问题，因为我尝试将数据保存在名为items_for_preview的列表中。但我不能将字符串保存到此列表中。我的应用说：无法解析“getString” 这是我的Getter_Setter_Events_Prev类：

String date;
String imageUrl;
String name;

public Getter_Setter_Events_Prev(String date, String imageUrl, String name) {
    this.date = date;
    this.imageUrl = imageUrl;
    this.name = name;
}

public String getDate() {
    return date;
}

public void setDate(String date) {
    this.date = date;
}

public String getImageUrl() {
    return imageUrl;
}

public void setImageUrl(String imageUrl) {
    this.imageUrl = imageUrl;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}

这是我的适配器类：

public class Customlist_upcoming_events extends RecyclerView.Adapter<Customlist_upcoming_events.ViewHolder> {
private List<Getter_Setter_Events_Prev> items;
private Context context;

public Customlist_upcoming_events(List<Getter_Setter_Events_Prev> items, Context context) {
    this.items = items;
    this.context = context;
}



@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.model_upcoming_events, parent, false);

    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    Getter_Setter_Events_Prev gt = items.get(position);
    holder.name.setText(gt.getName());
}

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

public class ViewHolder extends RecyclerView.ViewHolder {

    public TextView name;
    public ImageView pic;
    public ViewHolder(View itemView) {
        super(itemView);
        name = (TextView) itemView.findViewById(R.id.prev_events_name);
        pic = (ImageView) itemView.findViewById(R.id.event_thumb);

    }
}

}

无法将数据从MainActivity传递到RecyclerView适配器
