我想获得单选按钮和复选框的位置。因为它们在List中，所以当我滚动它们时会自动取消选中。我知道getView（）具有转换视图的属性，但我想做这个...我是这个概念的新手，请帮我找到解决方案...
提前致谢...
答案 0 :(得分：1)
您也可以自己管理视图。为您的商品创建每个独特的视图，不要回收视图。这样可以防止您的复选框被取消选中
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;
}
