example for parsing methods using Saxparsers

Step1 : for getting single tag value use below code:

public static ArrayList getListByTag(String msg,final String tag){

 

final ArrayList list=new ArrayList();

try{

list.clear();  

SAXParserFactory factory=SAXParserFactory.newInstance();

SAXParser parser=factory.newSAXParser();

// parser.parse(is, dh)//

parser.parse(new InputSource(new StringReader(msg)),new DefaultHandler(){

boolean tag_value=false; 

@Override

public void startElement(String uri, String localName,

String qName, Attributes attributes) throws SAXException {

super.startElement(uri, localName, qName, attributes);

if(qName.equalsIgnoreCase(tag)){

tag_value=true; 

}

 

} 

@Override

public void characters(char[] ch, int start, int length)

throws SAXException {

super.characters(ch, start, length);

if(tag_value){

list.add(new String(ch,start,length));  

}

}   

@Override

public void endElement(String uri, String localName, String qName)

throws SAXException {

super.endElement(uri, localName, qName);

if(qName.equalsIgnoreCase(tag)){

tag_value=false; 

} 

}

});  

}catch (Exception e) {

e.printStackTrace(); 

}

return list; 

}  

Step 2 : for getting list of tag values use below code:

public static ArrayList> getListofHouseHoldsByTag(String msg , final String tag){

final ArrayList>  list_values=new ArrayList>();  

 

try{

SAXParserFactory factory=SAXParserFactory.newInstance();

SAXParser parser=factory.newSAXParser();

 

parser.parse(new InputSource(new StringReader(msg)),new DefaultHandler(){

ArrayList list;

boolean tag_value=false; 

@Override

public void startElement(String uri, String localName,

String qName, Attributes attributes) throws SAXException {

super.startElement(uri, localName, qName, attributes);

if(qName.equalsIgnoreCase(tag)){

tag_value=true; 

list=new ArrayList();

}  

 

}

@Override

public void characters(char[] ch, int start, int length)

throws SAXException {

super.characters(ch, start, length);

if(tag_value){

list.add(new String(ch,start,length));  

} 

}   

@Override

public void endElement(String uri, String localName, String qName)

throws SAXException {

super.endElement(uri, localName, qName);

if(qName.equalsIgnoreCase(tag)){

tag_value=false;  

list_values.add(list);   

}

}

});  

}catch (Exception e) {

e.printStackTrace(); 

}

return list_values;   

} 

expandablelistview example in android

Step1: Create a project with the name of MainActivity.

Step2: design activity_main.xml and add code as below..
 
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

            android:id="@+id/laptop_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"/>  




Step3: add new xml file with the name of  group_item.xml and add code as below.

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

            android:id="@+id/laptop"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Small Text"
        android:paddingLeft="25dp"
        android:textAppearance="?android:attr/textAppearanceSmall" />




Step4: add new xml file with the name of  Child_item.xml and add code as below.

    android:layout_width="match_parent"
    android:layout_height="match_parent">

              android:id="@+id/delete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:src="@drawable/ic_delete"
        android:contentDescription="@string/app_name"/>

              android:id="@+id/laptop"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/delete"
        android:layout_alignParentLeft="true"
        android:text="textview"
        android:paddingLeft="25dp" />





Step5: add code in MainActivity.java

package com.example.expandablelistviewex;

import java.util.ArrayList;
import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;

import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.View;
import android.widget.ExpandableListView;
import android.widget.ExpandableListView.OnChildClickListener;
import android.widget.Toast;

public class MainActivity extends Activity
{
ExpandableListView expListView;
List groupList;
List childList;
Map> laptopCollection;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
expListView=(ExpandableListView)findViewById(R.id.laptop_list);
createGroupList();
createCollection();

final ExpandableListAdapter expandableListadapter=new ExpandableListAdapter(this,groupList,laptopCollection);
expListView.setAdapter(expandableListadapter);

//setGroupIndicatorToRight();
expListView.setOnChildClickListener(new OnChildClickListener()
{
           public boolean onChildClick(ExpandableListView parent, View v,int groupPosition, int childPosition, long id)
           {
               final String selected = (String) expandableListadapter.getChild(groupPosition, childPosition);
               Toast.makeText(getBaseContext(), selected, Toast.LENGTH_LONG).show();
         
               return true;
           }
       });
}
public void createGroupList()
{
groupList=new ArrayList();
groupList.add("HP");
        groupList.add("Dell");
        groupList.add("Lenovo");
        groupList.add("Sony");
        groupList.add("HCL");
        groupList.add("Samsung");
}

public void createCollection()
{
String[] hpModels = { "HP Pavilion G6-2014TX", "ProBook HP 4540","HP Envy 4-1025TX" };
String[] hclModels = { "HCL S2101", "HCL L2102", "HCL V2002" };
String[] lenovoModels = { "IdeaPad Z Series", "Essential G Series","ThinkPad X Series", "Ideapad Z Series" };

String[] dellModels = { "Inspiron", "Vostro", "XPS" };
String[] samsungModels = { "NP Series", "Series 5", "SF Series" };

laptopCollection=new LinkedHashMap>();
        for(String laptop:groupList)
        {
        if(laptop.equalsIgnoreCase("HP"))
        {
        loadchild(hpModels);
        }
        else if(laptop.equalsIgnoreCase("Dell"))
        {
        loadchild(dellModels);
        }
        else if(laptop.equalsIgnoreCase("Lenovo"))
        {

        }
        else if(laptop.equalsIgnoreCase("HCL"))
        {
        loadchild(hclModels);
        }
        else if(laptop.equalsIgnoreCase("Samsung"))
        {
        loadchild(samsungModels);
        }
       
       
        laptopCollection.put(laptop, childList);
        }
}
private void loadchild(String[] laptopmodels)
{
childList=new ArrayList();
for(String models:laptopmodels)
{
childList.add(models);
}
}

private void setGroupIndicatorToRight()
{
        /* Get the screen width */
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int width = dm.widthPixels;
        expListView.setIndicatorBounds(width - getDipsFromPixel(35), width- getDipsFromPixel(5));
    }
private int getDipsFromPixel(float pixels)
{
 // Get the screen's density scale
        final float scale = getResources().getDisplayMetrics().density;
        // Convert the dps to pixels, based on density scale
        return (int) (pixels * scale + 0.5f);
}

}

Step6: Add adapter class with the name of  ExpandableListAdapter.java and add the following code like as below.

package com.example.expandablelistviewex;

import java.util.List;
import java.util.Map;

import android.app.AlertDialog;
import android.content.DialogInterface;
import android.graphics.Typeface;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseExpandableListAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class ExpandableListAdapter extends BaseExpandableListAdapter
{
MainActivity mainActivity;
List laptops;
Map> laptopCollection;

public ExpandableListAdapter(MainActivity mainActivity,List groupList, Map> laptopCollection) 
{

this.mainActivity=mainActivity;
this.laptops=groupList;
this.laptopCollection=laptopCollection;
}


public Object getChild(int groupPosition, int childPosition)
{
// TODO Auto-generated method stub
return laptopCollection.get(laptops.get(groupPosition)).get(childPosition);
}

public long getChildId(int groupPosition, int childPosition)
{
// TODO Auto-generated method stub
return childPosition;
}

public View getChildView(final int groupPosition, final int childPosition,boolean isLastChild, View convertView, ViewGroup parent)
{

String laptop=(String)getChild(groupPosition, childPosition);

LayoutInflater inflater = mainActivity.getLayoutInflater();

if(convertView==null)
{
convertView = inflater.inflate(R.layout.child_item, null);
}

TextView item = (TextView) convertView.findViewById(R.id.laptop);


item.setTypeface(null, Typeface.BOLD);
item.setText(laptop);
       ImageView delete = (ImageView) convertView.findViewById(R.id.delete);
       delete.setOnClickListener(new OnClickListener() {
         
           public void onClick(View v) {
               AlertDialog.Builder builder = new AlertDialog.Builder(mainActivity);
               builder.setMessage("Do you want to remove?");
               builder.setCancelable(false);
               builder.setPositiveButton("Yes",
                       new DialogInterface.OnClickListener() {
                           public void onClick(DialogInterface dialog, int id) {

                       });
               AlertDialog alertDialog = builder.create();
               alertDialog.show();
           }
       });

return convertView;
}
public int getChildrenCount(int groupPosition)
{
return laptopCollection.get(laptops.get(groupPosition)).size();
}

public Object getGroup(int groupPosition)
{
return laptops.get(groupPosition);
}

public int getGroupCount()
{
return laptops.size();
}

public long getGroupId(int groupPosition)
{
// TODO Auto-generated method stub
return groupPosition;
}

public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent)
{
String laptopname=(String)getGroup(groupPosition);

if(convertView==null)
{
LayoutInflater infalInflater = (LayoutInflater)mainActivity.getSystemService(mainActivity.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.group_item,null);
}
TextView item = (TextView) convertView.findViewById(R.id.laptop);
item.setText(laptopname);
return convertView;
}

public boolean hasStableIds()
{
// TODO Auto-generated method stub
return true;
}

public boolean isChildSelectable(int groupPosition, int childPosition)
{
// TODO Auto-generated method stub
return true;
}

}

ApplicationConstants.java:

package com.example.telephonyex;

import java.util.ArrayList;

public class ApplicationConstants {
public static ArrayList list;

}

Step 4:
Note:write this code in MainActivity.java class
MainActivity.java:

package com.example.telephonyex;

import java.util.ArrayList;
import java.util.StringTokenizer;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.EditText;

public class MainActivity extends Activity {

static String to;
static String msg;
static String sub;



@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
 

public void sms(View v){

EditText et1=(EditText)findViewById(R.id.editText1);
EditText et2=(EditText)findViewById(R.id.editText2);

SmsManager manager=SmsManager.getDefault();

manager.sendTextMessage(et1.getText().toString(), null, et2.getText().toString(),null, null);
 
}

public void call(View v){

EditText et1=(EditText)findViewById(R.id.editText1);

Intent i=new Intent();
i.setAction(Intent.ACTION_CALL);
i.setData(Uri.parse("tel:"+et1.getText().toString()));
startActivity(i);





}



public void sendMail(View v){

EditText et3,et4,et5;


et3=(EditText)findViewById(R.id.editText3);
et4=(EditText)findViewById(R.id.editText4);
et5=(EditText)findViewById(R.id.editText5);



Intent i=new Intent();
i.setAction(Intent.ACTION_SEND);

i.putExtra(Intent.EXTRA_EMAIL,new String[]{et3.getText().toString(),});
i.putExtra(Intent.EXTRA_SUBJECT,new String[]{et4.getText().toString()});
i.putExtra(Intent.EXTRA_TEXT,new String[]{et5.getText().toString()});


i.setType("message/rfc822"); // this is used to enable MIME

startActivity(Intent.createChooser(i, "Select Any Email Client ..."));


// ArrayList list=new ArrayList();
//list.add(msg);
}


public void sendJavamail(View v){


EditText et3,et4,et5;


et3=(EditText)findViewById(R.id.editText3);
et4=(EditText)findViewById(R.id.editText4);
et5=(EditText)findViewById(R.id.editText5);

to=et3.getText().toString();
sub=et4.getText().toString();
msg=et5.getText().toString();

ArrayList list=new ArrayList();
   StringTokenizer tokenizer = new StringTokenizer(to, ";");
        while(tokenizer.hasMoreTokens())
        {
           list.add(tokenizer.nextToken());
        }
        ApplicationConstants.list=list;

   LongOperation operation=new LongOperation();
operation.execute();

}
}

Step5:

Note: write below permissions in AndroidManifest.xlm file

  

   

  

 

example for listview setonitemclicklistener in android

Step 1:
activity_main.xml:


    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

   
        android:id="@+id/listView1"
        android:layout_width="200dp"
        android:layout_height="480dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" >
   

   
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="16dp"
        android:layout_marginTop="179dp"
        android:layout_toRightOf="@+id/listView1"
        android:text="" />




Step 2:
MainActivity.java

package com.example.list;

import java.util.ArrayList;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
   

  final ListView list=(ListView)findViewById(R.id.listView1);
  String[] values=new String[]{"Kiran","Shiva","mahesh","Sathish","vanka","Pavan","Swathi"};
  ArrayAdapter adapter=new ArrayAdapter(getApplicationContext(),android.R.layout.select_dialog_multichoice ,values);
  list.setAdapter(adapter);
  list.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView arg0, View arg1, int arg2,
long arg3) {
//int a=list.getPositionForView(arg2);
int position=arg2;
tv=(TextView)findViewById(R.id.textView1);

String a="position is:"+(position+1)+"\n"+"name is:"+ list.getItemAtPosition(arg2).toString();
tv.setText(a);
           // Toast.makeText(getApplicationContext(), "position is:"+position+"name is:"+ list.getItemAtPosition(arg2).toString(),2000).show();
}
});
 
}


}
