lists变量是最终变量，用于指向特定位置的单击中。当视图被回收时。列表保持不变，因此可以获得重复项。请参见，您需要将更改保存在一个区域中，并更改从Thayener selam读取的项目（如列表），她在《凯塔·比尔米格斯特梅克》中饰演的亚尼在《凯蒂·尤克尔·尤尔松·索拉》中饰演的儿子凯蒂·塔格伦斯·耶尼在《凯蒂·米克·尤尔梅耶·阿尔》中饰演的角色让人耳目一新yorsun@ErsinG尤尔巴哈英语。这是英语问答site@Raghunandan当然，我会的。更有趣的是，我对电话列表使用了相同的适配器，但效果非常好。无论如何，我总是在我的每一个项目中使用列表适配器，但这是我第一次遇到这样的错误@谢谢你的链接。我刚刚读了它，但我不能为我的listview确定宽度和高度。谢谢回复。我已经做了，但不知怎么的，它不起作用。另一个问题是，当我单击列表中#1项处的复选框并快速从上到下从下到上滚动列表，然后在列表视图中选中#1处的复选标记“移动到随机项”。非常非常奇怪的情况。维护一个数组，如ArrayList arrayBool=new ArrayList（）；在checkBox onClick方法中，保持类似arrayBool[position]=checkBox.isChecked（）；在getView方法中，keep like checkBox.setChecked（arrayBool[position]）；这将解决您的问题。用Map更改了我的答案。请检查此解决方案。我很抱歉，我不能处理这种情况，我想我需要更多的实际例子和更多的展示案例。
