我想单选按钮的位置和复选框。因为那些在列表中，所以当我滚动那些会自动取消选中。我知道getView（）具有将视图的属性，但我想要做的这一个...我是新的这个概念，请帮我找到解决办法......

在此先感谢。 ..

您还可以管理自己的看法。为您的物品创建每一个独特的视图，不回收view.This将防止您的复选框得不到检查

private Map<Integer, View> myViews = new HashMap<Integer, View>(); 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    ViewHolder holder; 
    View view = myViews.get(position); 
    if (view == null) { 
     view = myInflater.inflate(R.layout.list_add_friends_row, null); 
     //don't need use the holder anymore. 

     //Your code 
     myViews.put(position, view); 

    } 
    return view; 
}
