OnClick在RecyclerView适配器中未触发

Question

我的RecyclerView包含单选按钮。当我点击一个我的下面的实现应该取消选择所有其他（notifyDataSetChanged()应重新绑定所有行）。出人意料的是，onClick永远不会触发：

public class NameAdapter extends RecyclerView.Adapter<NameAdapter.NameHolder> { 

    private List<String> myNames; 
    private int selectedPosition = -1; 

    public NameAdapter(List<String> names) { 
     myNames = names; 
    } 

    @Override public NameHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     Context context = parent.getContext(); 
     View view = LayoutInflater.from(context).inflate(R.layout.name_item, parent, false); 
     return new NameHolder(view); 
    } 

    @Override public void onBindViewHolder(NameHolder holder, int position) { 
     String name = myNames.get(position); 
     holder.name.setText(name); 
     holder.radioButton.setChecked(position == selectedPosition); 
    } 

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

    public class NameHolder extends RecyclerView.ViewHolder { 

     private TextView name; 
     private RadioButton radioButton; 

     public NameHolder(View itemView) { 
      super(itemView); 
      name = (TextView) itemView.findViewById(R.id.name); 
      radioButton = (RadioButton) itemView.findViewById(R.id.radio_button); 
      View.OnClickListener clickListener = new View.OnClickListener() { 
       @Override public void onClick(View v) { 
        selectedPosition = getAdapterPosition(); 
        notifyDataSetChanged(); 
       } 
      }; 
      itemView.setOnClickListener(clickListener); 
     } 
    } 
}

使用下列方法之一触发点击事件。

public class NameHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

    private TextView name; 
    private RadioButton radioButton; 

     public NameHolder(View itemView) { 
      super(itemView); 
      name = (TextView) itemView.findViewById(R.id.name); 
      radioButton = (RadioButton) itemView.findViewById(R.id.radio_button); 
      itemView.setOnClickListener(this); 
     } 
     @Override 
     public boolean onClick(View v) { 
      //Put your code here 
     } 
    }
