Answer 1

You have to follow the following steps to get your work done

Step-1 You need to parse the xml. see http://xmlpull.org/v1/src/java/samples/MyXmlPullApp.java

Step-2 Create a bean class for Category. means all the category related data will be stored in that bean class

Step-3 Create an arraylist of that bean class

Step-4 Create a list view using that arraylist ( the list view will display only name of categories)

Step-5 Implement on itemclik listener on the list view. get the position. retrieve the data pass to the intent call second activity

Step-6 In the second activity create a listview and display the data whatever is passed by first activity

NetworkBean

public class NetWorkBean {
    String name;
    int id;
    NetWorkBean(String name, int id){
        this.name = name;
        this.id = id;
    }
    public String getNetWorkName(){
        return name;
    }
    public int getNetWorkId(){
        return id;
    }
}

CategoryBean

import java.util.ArrayList;


public class CategoryBean {
    String name;
    ArrayList<NetWorkBean> networkList;
    public CategoryBean(String name, ArrayList<NetWorkBean> networkList){
        this.name = name;
        this.networkList = networkList;
    }
    public String getNetWorkName(){
        return name;
    }
    public ArrayList<NetWorkBean> getNetWorkList(){
        return networkList;
    }
