如何在 CardView 项目中显示数字（1、2、3、..）？

Question

我有 CardView 类似 的项目，我想在类似 的卡片视图项目中显示数字

我可以在适配器中做什么来显示 1,2,3.. 等数字？取决于大小？我使用改造来显示数据

这是我的适配器：

public class TipsAdapter extends RecyclerView.Adapter<TipsAdapter.CustomViewHolder> {
List<TipsModel> employees;
 Context context;

public TipsAdapter(Context context,List<TipsModel> employees) {
    this.employees = employees;
    this.context=context;
}

@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.tipstrickitem, parent, false);

    return new CustomViewHolder(itemView);
}

@Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
   // TipsModel employee = employees.get(position);
    holder.employeeName.setText(employees.get(position).getTips());

}

@Override
public int getItemCount() {
    return employees.size();
    //return (employees == null) ? 0 : employees.size();

}

public class CustomViewHolder extends RecyclerView.ViewHolder {
    public TextView employeeName;

    public CustomViewHolder(View view) {
        super(view);
        employeeName = (TextView) view.findViewById(R.id.employeeName);

    }
}}

对齐受到干扰： enter image description here

Answer 1

改变 holder.employeeName.setText(employees.get(position).getTips());

到holder.employeeName.setText(" " + position + ". " + employees.get(position).getTips());

这会将回收器视图的每个元素的位置作为一个数字添加到提示之前。

如果你想用String.valueOf(position+1)跳过零替换位置
