Android 使用RecyclerView绑定数据

我正在使用RecyclerView显示数据。但是，当我试图在onBindViewHolder（）方法中绑定数据时，我得到以下错误

我的适配器的代码如下所示，其中还包括ViewHolder类：

public class MyEmployeeAdapter extends RecyclerView.Adapter<MyEmployeeAdapter.EmployeeViewHolder> {
private List<ModelEmployee> empItemList;
private Context mContext;

public MyEmployeeAdapter(Context context, List<ModelEmployee> feedItemList) {
    this.empItemList = feedItemList;
    this.mContext = context;
}

@Override
public EmployeeViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.rowlayout_emp, null);

    EmployeeViewHolder viewHolder = new EmployeeViewHolder(view);
    return viewHolder;
}

@Override
public void onBindViewHolder(EmployeeViewHolder holder, int position) {
    ModelEmployee feedItem = empItemList.get(position);
    Log.d("NAME : ", feedItem.getName());
    Log.d("AGE : ", String.valueOf(feedItem.getAge()));
    holder.txtName.setText(feedItem.getName());
    holder.txtAge.setText(feedItem.getAge());

}


@Override
public int getItemCount() {
    return (null != empItemList ? empItemList.size() : 0);
}

public class EmployeeViewHolder extends RecyclerView.ViewHolder {

    public TextView txtName;
    public TextView txtAge;

    public EmployeeViewHolder(View view) {
        super(view);

        this.txtName = (TextView) view.findViewById(R.id.name);
        this.txtAge = (TextView) view.findViewById(R.id.age);
    }
}
}

请告诉我发生在我身上的错误的事情…

改变

holder.txtAge.setText(feedItem.getAge());

到

---

您正在setText方法中传递整数值，因此它将在String.xml文件中检查字符串。所以必须将整数值转换为字符串值

问题在于，android将您的

feedItem.getAge（）

解释为资源ID，并试图从

string.xml

获取相应的字符串资源

---

因此，引发了一个运行时异常（未找到资源），而不是编译器错误。

非常感谢您帮助我发现了我的愚蠢错误。现在工作正常了。。。

holder.txtAge.setText(feedItem.getAge());

holder.txtAge.setText(String.valueOf(feedItem.getAge()));
