我这里有点问题，
我做了一个可扩展的清单，但是这里的问题，就是当我检查一个盒子检查另一个盒子时，我无法找到原因，请我需要你的帮助。这是代码：
此代码在我的主要活动中：
/*
* Preparing the list data
*/
private void prepareListData() {
listDataHeader = new ArrayList<String>();
listDataChild = new HashMap<String, List<String>>();
// Adding child data
listDataHeader.add("By Body Part");
listDataHeader.add("By Objectives");
listDataHeader.add("By Muscle");
listDataHeader.add("By Equipments");
listDataHeader.add("By Sports");
listDataHeader.add("By Level");
// Adding child data
List<String> bodyPart = new ArrayList<String>();
List<String> objectives = new ArrayList<String>();
List<String> muscleGroup = new ArrayList<String>();
List<String> equipment = new ArrayList<String>();
List<String> sports = new ArrayList<String>();
List<String> level = new ArrayList<String>();
level.add("Easy");
level.add("Medium");
level.add("Hard");
if (shareAll.getFilteredItem() != null) {
if (!shareAll.getFilteredItem().isFilteredItemEmpty()) {
}
}
// dataController.getinstance.get ...是一个将数据库中的列表调用到的方法 //列在下面的代码中 if（isNetworkAvailable（）＆amp;＆amp; isBodyTableEmpty（））{
listDataChild.put(listDataHeader.get(0), DataController
.getInstance(getApplicationContext())
.getAllBodyPartsNames());
listDataChild.put(listDataHeader.get(1), DataController
.getInstance(getApplicationContext())

答案 0 :(得分：1)
这是因为listview重用它是节省内存的视图。
建议的解决方案： 您必须在数组中保存所选复选框项的位置，然后根据数组检查或取消选中getChildView中的视图
