根据用户选择对列表视图项进行持久更改
Make persistent changes to listview items based on user selections
所以几年后我又回到了 android 编程，我正在为一些我认为非常简单的事情而苦苦挣扎。我正在使用具有自定义布局的自定义数组适配器填充列表视图。
基本上，数组列表的每个项目都是一个自定义 class（命名卡），具有 4 个属性：(int)id、(String)name、(boolean)include、(int)deck（想法是用户选择要包含在 3 副不同牌组中的每副牌）。
我创建了一个简单的布局，其中包含 2 个文本视图、1 个复选框和 1 个单选组，里面有 3 个单选按钮（和一堆图标）（见下文）。
我的问题是，尽管列表视图被填充并且显示正确，但每当我（用户）更改某些内容（例如点击复选框或单选按钮）并滚动时，一切都搞砸了（我所做的选择被复制到其他行）。我尝试在适配器的 getView() 方法中设置侦听器并通知数据更改，但无济于事。我知道视图会被回收，但显然我不明白如何回收。任何帮助将不胜感激。

这是 MainActivity 中我设置适配器的部分：

listView = findViewById(R.id.lv_cards);
AdapterCard adapter = new AdapterCard(this,list);
listView.setAdapter(adapter);
编辑： 我忘了补充一点，最终目标是通过遍历整个列表来恢复所有用户选择。至此我已经成功获取了Card对象，但是由于滚动时位置发生变化，所以没有用：
for(int i = 0; i < adapter.getCount(); i++){
Card card_i = adapter.getItem(i);
// retrieve card data to generate the decks
}
我最终设法通过简单地将我感兴趣的状态存储在布尔列表中并监听“点击”而不是更改状态来做到这一点。适配器现在看起来：
