我正在努力使OnClickListener
用于每个项目,并在每一行中获取数据。
我需要的是获取我单击的每一行的名称,但是,o只能获得该位置。有人可以帮我吗?
这是显示我需要的名字的屏幕截图。
我需要在此处输入NAME
,但是,我只能获取该行的位置。我该如何取每一行的名字?
这是我的密码

最佳答案
您可以将点击侦听器的设置移动到onBindViewHolder
:
protected void onBindViewHolder(UsersViewHolder holder, int position, User model) {
holder.bind(model);
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d("viewholder", " " + holder.getAdapterPosition());
Log.d("viewholder", " " + model.getUsername());
}
});
}
