我正在尝试创建一个自定义列表，其中包含允许您从列表中选择多个项目的复选框。

I'm trying to create a custom list which will have checkboxes that allow you to select several items from the list.

带有复选框的列表显示为ok但是如果我检查一个复选框，然后滚动其他项目进一步向下列表也被检查。

The list with the checkboxes is displayed ok but if i check a checkbox and then scroll other items further down the list are also checked.

它基本上与这里

我知道它和android的方式有关回收视图，但我不能看到如何解决这个问题！有人可以帮助我吗？

I understand that it has something to do with the way android recycles the view but I cant see how to fix this! Can somebody help me???

推荐答案

您需要一个数据结构来跟踪哪些行被选中。这可以像 bool [] checked 一样简单。

You need a data structure to keep track of which rows are checked. This could be as simple as a bool[] checked.

在 getView ，请确保将复选框状态设置为 checked [position] 的内容。您还应在您的网站上设置OnCheckedChangedListener 在 getView 中的复选框，以便他们使用 checked [position] = isChecked 更新您的数据。

In your getView, make sure that you set the checkbox state to the contents of checked[position]. You should also set an OnCheckedChangedListener on your check boxes in getView so that they update your data with checked[position] = isChecked.

是的， ListView 中的行被回收，因此请确保填充一行的所有适当数据，然后再保留 getView 。

Yes, the rows in a ListView are recycled, so make sure to populate all the appropriate data for a row before you leave getView.
