java - 如何在自定义适配器 Android Studio Java 中将标签设置为行

Question

我正在尝试为该行设置一个标签(或者至少为该行中的某些内容，最好是该行)。然后当我点击该行时，我可以获得标签。我认为这是我必须做的，但无论我点击什么，标签始终为空。

我的代码示例显示了我尝试将标签设置为 TextView ，因为我不知道如何将其设置为行。

这是我的 customAdapter 类中的 getView 代码

int counter = 0;

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater layoutInflater = LayoutInflater.from(getContext());

    View customView = layoutInflater.inflate(R.layout.my_row, parent, false);

    ViewHolder holder = new ViewHolder();

    holder.name = (TextView)customView.findViewById(R.id.nameTextView);
    holder.picture = (ImageView)customView.findViewById(R.id.pictureImageView);

    holder.name.setText(allNames.get(position));
    holder.picture.setImageResource(allPictures.get(position));

    //This does not work ---> holder.name.setTag(counter);

    counter ++;
    return customView;
}

这是我在不同类中的 onClickListener

listVIew.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, final int position, long l) {

           Toast.makeText(getApplicationContext(), "tag is " + view.getTag(), Toast.LENGTH_SHORT).show();

        }
    });

如有任何帮助，我们将不胜感激。谢谢。

试试这个，

@Override
    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater layoutInflater = LayoutInflater.from(getContext());

        View customView = layoutInflater.inflate(R.layout.my_row, parent, false);

        ViewHolder holder = new ViewHolder();

        holder.name = (TextView)customView.findViewById(R.id.nameTextView);
        holder.picture = (ImageView)customView.findViewById(R.id.pictureImageView);

        holder.name.setText(allNames.get(position));
        holder.picture.setImageResource(allPictures.get(position));

        //This does not work ---> holder.name.setTag(counter);

        customView.setTag(Integer.valueOf(counter));

        counter ++;
        return customView;
    }
