Java 带有复选框onclicklistener的android listview不工作

Java 带有复选框onclicklistener的android listview不工作,java,android,listview,arraylist,checkbox,Java,Android,Listview,Arraylist,Checkbox,我有一个带有自定义适配器的listview。在listview上我有textview图像和复选框。工作正常。当我点击项目时,我有一个arraylist,该项目值存储在arraylist中,当我再次点击项目值从数组列表中移除时,效果很好。问题是当我点击复选框值不存储在arraylist中时,问题是什么我尽了最大努力但没有解决我的问题。我想当我点击项目或复选框时,它的值存储在arraylist中,这里是我的自定义适配器代码 public class Listadapter extends BaseA
