我的适配器的代码如下，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);
    }
}
}

卡在以下几行:

 @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());

}

拜托，让我知道发生在我身上的错误...

Answer 1

改变

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

到

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

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