Android:在点击可点击范围时，使ListView行中的特定小部件可见

// 在适配器中设置特定小部件的标识符
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // 获取行的视图
    View rowView = convertView;
    if (rowView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        rowView = inflater.inflate(R.layout.list_item, parent, false);
    }

    // 获取特定小部件
    TextView textView = (TextView) rowView.findViewById(R.id.textView);
    Button button = (Button) rowView.findViewById(R.id.button);

    // 设置特定小部件的标识符
    button.setTag(position);

    // 设置点击事件监听器
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // 获取被点击行的特定小部件的标识符
            int position = (int) v.getTag();

            // 根据标识符找到对应的特定小部件，并设置其可见性为可见
            TextView textView = (TextView) listView.getChildAt(position).findViewById(R.id.textView);
            textView.setVisibility(View.VISIBLE);
        }
    });

    return rowView;
}
