我已经解析了 json 数据，其中有一个主 json 数组，它包含子 json 数组。但主 json 数组不包含每个项目中的子 json 数组。所以我已经解析了所有的数据。我从中得到了完美的数据。但问题是主 json 数组数据显示在列表视图中，单击列表视图项后，子 json 数组根据主 json 数组项显示，但它仅从哈希映射数组列表中获取子 json 数组的最后一个元素。所以我无法获得正确的显示方式，所以请找出一些标准解决方案。

这是我的代码

类 AllCategories 数据：

public class Allcategories {

// private List subcategories;

    // TODO Auto-generated constructor stub
    this.categoryname = name;
    this.categorystorecount = count;

public String getCategoryname() {

}

public void setCategoryname(String categoryname) {
    this.categoryname = categoryname;
}

public String getCategorystorecount() {
    return this.categorystorecount;
}

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

子类别数据类：

public class subCateData {

String subcatId, subcategoryname, subcategorystorecount;

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

public String getsubcatId() {
    return this.subcatId;
}

public void setsubcatId(String subID) {
    this.subcatId = subID;
}

public String getsubcatname() {
    return this.subcategoryname;
}

public void setsubcatname(String name) {
    this.subcategoryname = name;
}

public String getsubcatcount() {
    return this.subcategorystorecount;
}

public void setsubcatcount(String count) {
    this.subcategorystorecount = count;
}

您应该必须将新的 HashMap 放入当前的 HasHMap 中，以便您可以获得特定索引的子类别项。

看到这个如何使用嵌套的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。因此，如果您可以将代码转换为 arraylist 并编辑将是一个很棒的问题..

并查看下面的代码

import java.util.ArrayList;

public class MainCategories extends Fragment {
WebserviceClass wservice = new WebserviceClass();
Context c;
View v;
String data = "";
String User_id, countryid;
JSONObject jobj;

// testAdapter adapter

int limit = 3, id;

String name, count;
String subname, subcount, subCategoryId;
