如何为由recyclerview填充的每个按钮设置不同的onclick侦听器

您可以使用 Switch statement 基于中的职位 onBindViewHolder . 例如:

Switch(position){
case 0:
//Button No.1
break;
case 1:
//Button No.2
break;
.....
}

为此,您可以检查recyclerview adapter onBindViewHolder中onclick of button中与按钮位置相关的条件。您可以在按钮单击中使用if(position==1){--do something--},if(position==2){--do other thing--}。

您需要在库中创建自定义适配器,下面的代码是示例:

   public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder> {
    Context context;
    List<Category> list;

    public CategoryAdapter(Context context, List<Category> list){
        this.list = list;
    }
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View view = inflater.inflate(R.layout.item_category, null);
        return new CategoryAdapter.ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final ViewHolder holder, int position) {

        viewHolder.btnOne.setOnItemClickListener(new View.OnItemClickListener{
// do something
});
    }

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

    public class ViewHolder extends RecyclerView.ViewHolder {
        Button btnOne, btnTwo;
        public ViewHolder(View view) {
            super(view);
            btnOne = view.findViewById(R.id.btn_one);
            btnTwo = view.findViewById(R.id.btn_two);

        }
    }

}

Ge您的按钮参考;将每个onClick侦听器放在onBindViewHolder()方法中。
