【中文标题】Android Listview 多个按钮点击【英文标题】：Android Listview multiple buttons click 【发布时间】：2017-02-12 16:43:59 【问题描述】：我的问题是关于列表视图的多个按钮单击。例如我的列表视图包含 3 行，每行包含 3 个按钮。当我点击第一行的第一个按钮时，它会改变最后一行第一个按钮的颜色
please check image you will know the problem
我尝试使用按钮标签、视图持有者来解决它，尝试将位置分配给按钮但仍然没有发生任何事情

【问题讨论】：
你需要使用 ViewHolder 模式。在上面的代码中发生的是最后添加按钮的颜色正在更新它是自然的...... 那是什么？你很难过我想在同一行改变颜色。并想象你的例子，改变相同的行颜色？确定要问什么？ 嗨，请尝试在列表视图中使用视图持有者模式实现我编辑的答案。 它在 gridview 项目单击中解决了同样的问题，如果您有任何疑问，请告诉我 【参考方案1】：试试这个简单的答案：
通过您设置的标签找到您的按钮视图。
((Button) convertView.findViewWithTag(position)).setBackgroundColor(Color.GRAY);
您遇到此问题是因为您的适配器持有的最后一个 accept_btn 对象是它创建的最后一个视图对象。
因此，通过在按钮上设置标签，您就在正确的轨道上。但是您必须通过标签检索该视图。 让我知道这是否有帮助。
谢谢。
【讨论】：
是的。但是，他接下来会遇到的问题是，所有设置了相同 TAG 的按钮都会改变颜色。从那里他可以弄清楚如何为每个按钮设置不同的标签名称。此外，这个适配器将来可能会遇到更多问题，但这个答案将帮助他弄清楚他最初的问题。【参考方案2】：我已经在 gridview HERE 中写了相同问题的答案。您可以使用相同的技巧来解决此问题。 // 简单的想法
您可以实现自己的自定义 OnClickListener，并且可以为每个列表视图项的每次点击关联 id/tag/position。
yourBtn.setOnclickListener(new BtnClick(position, btnid));
自定义 OnclickListener：
Class BtnClick View.OnClickListener
int position;
int btnId;
Public BtnClick(int position, int id)
this.position = position;'
this.btnId = btnId;
@Override
public onClick(View v)
// You can add logic here for each item clicked using position and id of each item you passed in constructor
