仅获取hashmap arraylist中的最后一项数据

Question

我已经解析了json数据，其中有一个主要的json数组，它包含子json数组。但主要的json数组在每个项目中都不包含子json数组。所以我已经解析了所有数据。我从中获得了完美的数据。但问题是主json数组数据显示在listview中，点击列表视图项后，子json数组显示为主json数组项，但它只从哈希映射数组列表中获取子json数组的最后一个元素。所以我无法正确显示，所以请找出一些标准的解决方案。

这是我的代码

public void setCategorystorecount(String categorystorecount) {
    this.categorystorecount = categorystorecount;

SubCategory数据类：

public class subCateData {

public subCateData(String id, String name, String count) {
    // TODO Auto-generated constructor stub
    this.subcatId = id;

你必须在当前的HasHMap中放入新的HashMap，这样你才能获得特定索引的子类别项。

请参阅this了解如何使用嵌套的HashMap？并在子类别循环中使用它。

我正在使用getter setter类的ArrayList来绑定数据。所以，如果你可以将你的代码转换成arraylist并编辑一个很棒的问题..

并参见下面的代码
