我的问题是关于listview多个按钮点击。例如我的列表视图包含3行，每行包含3个按钮。当我点击第一行中的第一个按钮时，它会改变最后一行第一个按钮的颜色
please check image you will know the problem
我试图使用按钮标签，视图持有人来解决它，试图将位置分配给按钮但仍然没有发生任何事情

答案 0 :(得分：0)
试试这个简单的答案：
按照您设置的标记找到您的按钮视图。
((Button) convertView.findViewWithTag(position)).setBackgroundColor(Color.GRAY);
您遇到此问题，因为您的适配器所持有的最后一个accept_btn对象是它创建的最后一个视图对象。
因此，您可以通过在按钮上设置标签来确定正确的方向。但是你必须通过标签检索该视图。 如果这有用，请告诉我。
感谢。

我已经在gridview HERE中为同样的问题写了答案。您可以使用相同的技巧来解决此问题。 //简短的想法
您可以实现自己的自定义OnClickListener，并且可以为listview的每个项目的每个onclick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
}
}
