here

i am trying to print dynamically particular group name and its child data like header and its contents .

but i m able to pring group name in header that is no issue.

But the problem is, i m also getting the group name instead of child contents

link to my code

here is the code: SectionDemo.java

package com.bestdambikers;

import java.util.List;

public class SectionedDemo extends ListActivity {

      DetailBean dBean;
      XmlParser parser;
      ArrayList<Object>  result;
      List<DetailBean> list;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.header_main);

        //dBean = new DetailBean();
        parser = new XmlParser(strUrl, new DetailBean());
        result = parser.ParseUrl("data", "group");
        int r = result.size();

        for(int i=0; i<result.size(); i++)
        {

            dBean = (DetailBean)result.get(i);
            list=Arrays.asList(dBean);
            Collections.shuffle(list);
            adapter.addSection(dBean.group_name,
                new ArrayAdapter<DetailBean>(this,
                        android.R.layout.simple_list_item_1,

            if (convertView==null) {
                result=(TextView)getLayoutInflater()
                .inflate(R.layout.header,
                        null);
            }

            result.setText(caption);

            return(result);
        }
    };
}

and code for DetailBean.java

public class DetailBean

    {
        this.data = data;
        this.code = code;

    }
    @Override

        // You should populate this string with the data
        // you need inside the TextView
        return this.group_name + " " + this.data;
    }

Your xml suggests that you are dealing with a hierarchical data structure, so my advice would be to use ExpandableListView with a proper adapter.

Your bean structure should be rethought as well, to be able to hold hierarchy. For this you should split your DetailBean class, and leave in that only the groupName, code and fields members:

DetailBean.java

import java.util.ArrayList;

public class DetailBean
{
    private String groupName = null;
    private int code;
    private ArrayList<Field> fields;

    public String getGroupName()
    {
        return groupName;
    }

    public void setGroupName(String groupName)
    {
        this.groupName = groupName;
    }

    public int getCode()
    {
        return code;
    }

    public void setCode(int code)
    {
        this.code = code;
    }

    public ArrayList<Field> getFields()
    {
        return fields;
    }

    public void setFields(ArrayList<Field> fields)
    {
        this.fields = fields;
    }

    @Override
    public String toString()
    {
        // You should populate this string with the data
        // you need inside the TextView
        return this.groupName;
    }
}

And declare a new class named Field, to gather the child data:

Field.java

public class Field
{
    private int id;
    private String name;
    private String value;
    private boolean required;
    private String type;

    public int getId()
    {
        return id;
    }
    public void setId(int id)
    {
        this.id = id;
    }
    public String getName()
    {
        return name;
    }
    public void setName(String name)
    {
        this.name = name;
    }
    public String getValue()
    {
        return value;
    }
    public void setValue(String value)
    {
        this.value = value;
    }
    public boolean isRequired()
    {
        return required;
    }
    public void setRequired(boolean required)
    {
        this.required = required;
    }
    public String getType()
    {
        return type;
    }
    public void setType(String type)
    {
        this.type = type;
    }
}

I'd split the XmlParser class too, to have the handler part in a different class:

XmlHandler.java

public class XmlHandler extends DefaultHandler
{
    private static final String TAG_GROUP = "group";
    private static final String TAG_GROUPNAME = "group_name";
    private static final String TAG_FIELD = "field";
    private static final String TAG_CODE = "code";
    private static final String TAG_ID = "id";
    private static final String TAG_NAME = "name";
    private static final String TAG_VALUE = "value";
    private static final String TAG_REQUIRED = "required";
    private static final String TAG_TYPE = "type";
    private int code = 0;
    private String currentNodeName;
    private DetailBean currentGroup;
    private Field currentField;

    private ArrayList<DetailBean> records = null;
    private String elementValue;

    public ArrayList<DetailBean> getRecords()
    {
        return records;
    }

    @Override
    public void startDocument() throws SAXException
    {
        super.startDocument();
        this.records = new ArrayList<DetailBean>();
    }

    @Override
    public void startElement(final String Uri, final String localName, final String qName, 
            final Attributes attributes) throws SAXException
    {
        if (localName != null)
        {
            currentNodeName = localName;
        }
    }

    @Override
    public void characters(final char[] ch, final int start, final int length) throws SAXException
    {
        if (this.currentNodeName == null)
            return;
        this.elementValue = new String(ch, start, length).trim();

        if (this.currentNodeName.equalsIgnoreCase(TAG_CODE))
        {
            this.code = Integer.parseInt(this.elementValue);
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_GROUP))
        {
            this.currentGroup = new DetailBean();
            this.currentGroup.setCode(this.code);
            this.currentGroup.setFields(new ArrayList<Field>());
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_GROUPNAME))
        {
            this.currentGroup.setGroupName(this.elementValue);
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_FIELD))
        {
            this.currentField = new Field();
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_ID))
        {
            this.currentField.setId(Integer.parseInt(this.elementValue));
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_NAME))
        {
            this.currentField.setName(this.elementValue);
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_VALUE))
        {
            this.currentField.setValue(this.elementValue);
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_REQUIRED))
        {
            this.currentField.setRequired(Integer.parseInt(this.elementValue) > 0);
        }
        else if (this.currentNodeName.equalsIgnoreCase(TAG_TYPE))
        {
            this.currentField.setType(this.elementValue);
        }
    }

    @Override
    public void endElement(final String Uri, final String localName, final String qName) throws SAXException
    {
        if (localName.equalsIgnoreCase(TAG_GROUP))
        {
            if (this.currentGroup != null)
                this.records.add(this.currentGroup);
        }
        else if (localName.equalsIgnoreCase(TAG_FIELD))
        {
            if ((this.currentGroup != null) && (this.currentField != null))
                this.currentGroup.getFields().add(this.currentField);
        }
        currentNodeName = null;
    }
}

So your XmlParser class gets simpler:

XmlParser.java

public class XmlParser
{
    public ArrayList<DetailBean> parseFromUrl(final String xmlURL)
    {
        try
        {
            final URL sourceUrl = new URL(xmlURL);

Your SectionedDemo activity should extend ExpandableListActivity instead of ListActivity, and its onCreate method should look like:

@Override

public void onCreate(Bundle icicle)
{
    super.onCreate(icicle);

    getExpandableListView().setGroupIndicator(null);
    getExpandableListView().setDivider(null);
    getExpandableListView().setDividerHeight(0);

    parser = new XmlParser();
    result = parser.parseFromUrl(XML_URL);
    adapter = new MyExpandableListAdapter();

    setListAdapter(adapter);
}

Here is a sample output of an application following the instructions above, and using the xml source you provided:

Here is my main activity class for producing this output (without any resource code):
