my list view activity is here:(my list just show PatientId)



public class ViewAllPatientActivity extends ListActivity {
ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
XMLParser parser=new XMLParser();
static final String URL="http://ift.tt/1zc4Xp4";
static final String Parent_Node="Patient";
static final String Patient_ID="PatientId";
static final String First_Name="PatientFirstName";
static final String Last_Name="PatientLastName";
//static final String Blood_Type="BloodType";
//static final String Phone_Number="phoneNumber";
//static final String Practitioner_ID="practitionerId";
//static final String Email="Email";
//static final String URL="http://ift.tt/1l4gTGN";
//static final String Patient_ID="item";
//static final String First_Name="name";
//static final String Last_Name="cost";

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.all_patient);



    String xml=parser.GetXml(URL);
    Document doc=parser.DomElement(xml);
    if(doc==null){
        System.out.print("null");
    }
    else {

        NodeList nl = doc.getElementsByTagName(Parent_Node);
        for (int i = 0; i < nl.getLength(); i++) {
            HashMap<String, String> map = new HashMap<String, String>();
            Element e = (Element) nl.item(i);
            map.put(Patient_ID, parser.GetValue(e, Patient_ID));
            map.put(First_Name, parser.GetValue(e, First_Name));
            map.put(Last_Name, parser.GetValue(e, Last_Name));
           // map.put(Blood_Type,parser.GetValue(e,Blood_Type));
            //map.put(Phone_Number,parser.GetValue(e,Phone_Number));
            //map.put(Email,parser.GetValue(e,Email));
            //map.put(Practitioner_ID,parser.GetValue(e,Practitioner_ID));

            menuItems.add(map);
        }
        ListAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.list_item,
                new String[]{Patient_ID, First_Name, Last_Name}, new int[]{R.id.pid, R.id.fName, R.id.lName});
        setListAdapter(adapter);

        ListView lv = getListView();
        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                String Patient_id = ((TextView) view.findViewById(R.id.pid)).getText().toString();
                String First_name = ((TextView) view.findViewById(R.id.fName)).getText().toString();
                String Last_name = ((TextView) view.findViewById(R.id.lName)).getText().toString();

                Intent in = new Intent(getApplicationContext(), SingleListPatient.class);
                in.putExtra(Patient_ID, Patient_id);
                in.putExtra(First_Name, First_name);
                in.putExtra(Last_Name, Last_name);
                startActivity(in);
            }
        });
    }


it is my list:



<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://ift.tt/nIICcg"
android:layout_width="match_parent" android:layout_height="match_parent">
<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@android:id/list">
    </ListView>
</LinearLayout>


it is another activity:(in this page I have just FirstName)



public class SingleListPatient extends Activity {
@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.single_list_patient_view);
    TextView txtFN=(TextView)findViewById(R.id.firstN);
    TextView txtLN=(TextView)findViewById(R.id.lastN);
    TextView txtID=(TextView)findViewById(R.id.patientid);
    TextView txtBT=(TextView)findViewById(R.id.btype);
    TextView txtPN=(TextView)findViewById(R.id.pnum);
    TextView txtEM=(TextView)findViewById(R.id.mail);

    Intent i=getIntent();

    String FirstName=i.getStringExtra("PatientFirstName");
    String LastName=i.getStringExtra("PatientLastName");
    String ID=i.getStringExtra("PatientId");
    String BloodType=i.getStringExtra("BloodType");
    String PhoneNumber=i.getStringExtra("phoneNumber");
    String Email=i.getStringExtra("Email");

    txtFN.setText(FirstName);
    txtLN.setText(LastName);
    txtID.setText(ID);
    txtBT.setText(BloodType);
    txtPN.setText(PhoneNumber);
    txtEM.setText(Email);
}


and it is my list item:



<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://ift.tt/nIICcg"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal">
<TextView xmlns:android="http://ift.tt/nIICcg"
android:id="@+id/pid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip"
android:textSize="16dip"
android:textStyle="bold" />
<TextView xmlns:android="http://ift.tt/nIICcg"
    android:id="@+id/fName"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dip"
    android:textSize="16dip"
    android:textStyle="bold" />
<TextView xmlns:android="http://ift.tt/nIICcg"

    android:layout_height="fill_parent"
    android:padding="10dip"
    android:textSize="16dip"

</RelativeLayout>


and it is my Xml Parser class:



 public class XMLParser {
//get xml from http url
public String GetXml(String url){
    String xml=null;
    try{
        //open http connection via url
        DefaultHttpClient httpClient=new DefaultHttpClient();
        HttpPost httpPost=new HttpPost(url);
        HttpResponse httpResponse=httpClient.execute(httpPost);
        HttpEntity httpEntity=httpResponse.getEntity();
        //convert to a readable code or get xml content and close connection
        xml= EntityUtils.toString(httpEntity);

    }
    catch (UnsupportedEncodingException e){

    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return xml;
}

public Document DomElement(String xml){
    Document doc = null;;
    //factory API for DOM object trees for xml docs
    DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
    try{
        //Dom doc instance
        DocumentBuilder db=dbf.newDocumentBuilder();
        //parse doc to xml
        InputSource is=new InputSource();
        //place entire files into database columns that can hold large values,
        is.setCharacterStream(new StringReader(xml));
        doc= db.parse(is);

    }catch (ParserConfigurationException e) {
        Log.e("Error: ", e.getMessage());
        return null;
    } catch (SAXException e) {
        Log.e("Error: ", e.getMessage());
        return null;
    } catch (IOException e) {
        Log.e("Error: ", e.getMessage());
        return null;
    }
    //return DOM
    return doc;
}

public String GetValue(Element item,String st){
    //abstract node--give value of a node and put it on n
    NodeList n=item.getElementsByTagName(st);
    return this.getElementValue(n.item(0));

}

public final String getElementValue(Node element) {
    Node child;
    if (element !=null){
        if (element.hasChildNodes()){
            for (child=element.getFirstChild();child!=null;child=child.getNextSibling()){
                if (child.getNodeType()==Node.TEXT_NODE){
                    return child.getNodeValue();
                }
            }
        }
    }
    return "";
    }
}


thank you.
