如您所见，

ArrayList

“ShopItems”中存储的项目（

ShopItem

）

我想要什么： 单击

复选框

（正好在它上面。不要单击listview项目）使我的项目“

isDone

-true”，textview中的文本将更改颜色。 我的意思是，我想要

OnCheckedChangeListener

，它会影响我的对象，改变它的

isDone

布尔值

问题:

在checkedChangeListener上，我可以在哪里以及如何放置

 //在getView（）中，使用列表维护复选框状态

doneCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
             if(isChecked){
                doneCheckBox.ischecked=true;
            }
            else{
                doneCheckBox.ischecked=false;
            }
        }
    });

在CustomAdapter中的getview（）方法中在getview（）中写入OnCheckedChangeListner（）查看我的答案你会解决你的问题
