ANDROID - Sax Parsing (using raw data)

Demo:

1)SaxParsing1 Activity:

package com.venky.saxparsing1;

import java.io.IOException;

import java.util.Vector;

public class SAXParsing1Activity extends Activity {

      /** Called when the activity is first created. */

      ListView lvList;

      SAXParser saxParser;

      @Override

      public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);

            lvList = (ListView) findViewById(R.id.lvList);

            try {

                  saxParser = SAXParserFactory.newInstance().newSAXParser();

                  saxParser.parse(getResources().openRawResource(R.raw.sample),

                              new StudentHandler());

            } catch (ParserConfigurationException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (SAXException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (NotFoundException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (IOException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            }

            lvList.setAdapter(new MyArrayAdapter(new StudentHandler().getData()));

      }

      public class MyArrayAdapter extends BaseAdapter {

            public Vector<Student> vecStudent;

            public MyArrayAdapter(Vector<Student> vecStu) {

                  vecStudent = vecStu;

            }

            @Override

            public int getCount() {

                  // TODO Auto-generated method stub

                  return vecStudent.size();

            }

            @Override

            public Object getItem(int position) {

                  // TODO Auto-generated method stub

                  return vecStudent.size();

            }

            @Override

            public long getItemId(int position) {

                  // TODO Auto-generated method stub

                  return vecStudent.size();

            }

            @Override

            public View getView(int position, View v, ViewGroup parent) {

                  Student student = vecStudent.get(position);

                  v = (LinearLayout) getLayoutInflater()

                              .inflate(R.layout.style, null);

                  TextView tv1 = (TextView) v.findViewById(R.id.tvSno);

                  TextView tv2 = (TextView) v.findViewById(R.id.tvSname);

                  TextView tv3 = (TextView) v.findViewById(R.id.tvScity);

                  tv1.setText(student.sno);

                  tv2.setText(student.sname);

                  tv3.setText(student.scity);

                  return v;

            }

      }

}

2)StudentHandler Activity:

 

package com.venky.saxparsing1;

import java.util.Vector;

import org.xml.sax.Attributes;

import org.xml.sax.SAXException;

import org.xml.sax.helpers.DefaultHandler;

public class StudentHandler extends DefaultHandler {

      public static Vector<Student> vecStudent;

      Student student;

      StringBuffer currentString;

      @Override

      public void startElement(String uri, String localName, String qName,

                  Attributes attributes) throws SAXException {

            if (localName.equalsIgnoreCase("College")) {

                  if (vecStudent != null && vecStudent.size() > 0) {

                        vecStudent.clear();

                  } else

                        vecStudent = new Vector<Student>();

            }

            else if (localName.equalsIgnoreCase("Student")) {

                  student = new Student();

            }

            currentString = new StringBuffer();

      }

      @Override

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

                  throws SAXException {

            if (localName.equalsIgnoreCase("sno")) {

                  student.sno = currentString.toString();

            }

            else if (localName.equalsIgnoreCase("sname")) {

                  student.sname = currentString.toString();

            }

            else if (localName.equalsIgnoreCase("scity")) {

                  student.scity = currentString.toString();

            }

            else if (localName.equalsIgnoreCase("Student")) {

                  vecStudent.add(student);

            }

      }

      @Override

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

                  throws SAXException {

            currentString.append(ch, start, length);

      }

      public Vector<Student> getData() {

            return vecStudent;

      }

}

3)Student.java:

 

package com.venky.saxparsing1;

public class Student {

      String sno;

      String sname;

      String scity;

}
