我尝试在自定义列表视图中使用OnClickListener，但是当单击textview时（Onclicklistener运行）它在listview中的几个textview上运行代码！ 请参阅我的holder.tvComment.setOnClickListener 更新：

中的ListAdapter.class

答案 0 :(得分：0)

将setOnClickListener代码写入if条件

if (convertView == null) {
   .....
   .....
   // write here your holder.tvComment.setOnClickListener

   convertView.setTag(holder);
}

在此之前：

convertView.setTag(holder);

您的完整适配器将是这样的：
