XML 파서: XmlPullParser

XML 파서: XmlPullParser

1. xml 데이터

res에 raw 폴더를 만들어 student.xml 파일을 만든다.

<person>
    <student>
        <name>홍길동</name>
        <age>30</age>
        <address>서울</address>
    </student>
    <student>
        <name>이순신</name>
        <age>40</age>
        <address>전라도</address>
    </student>

    <student>
        <name>강감찬</name>
        <age>50</age>
        <address>경상도</address>
    </student>

</person>

2. 자바빈 생성

java 폴더에서 위의 xml 데이터를 기본으로 한 student.java라는 자바빈 클래스를 정의한다.

package com.progdv.xmlpullparser;

public class Student {

    String name;
    String age;
    String address;

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }
}

3. 레이아웃

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.progdv.xmlpullparser.MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">


    <ListView
        android:background="#314eac"
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    </LinearLayout>


</RelativeLayout>

4. xml 파일을 가져와서 뿌려주는 메인 액티비티

xmlPullParser 방식으로 가져온다.

package com.progdv.xmlpullparser;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import org.xmlpull.v1.XmlPullParserFactory;

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    ListView listView;

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

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

        ArrayList<Student> list = xmlParser();
        String[] data = new String[list.size()];
        for(int i=0;i<list.size();i++) {
            data[i] = list.get(i).getName()+" "+
                    list.get(i).getAge()+" "+list.get(i).getAddress();
        }
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),
                android.R.layout.simple_list_item_1,
                data);
        listView.setAdapter(adapter);
    }

    private ArrayList<Student> xmlParser()  {
        ArrayList<Student> arrayList = new ArrayList<Student>();
        InputStream is = getResources().openRawResource(R.raw.student);

        // xmlPullParser
        try {
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            XmlPullParser parser = factory.newPullParser();
            parser.setInput(new InputStreamReader(is, "UTF-8"));
            int eventType = parser.getEventType();
            Student student = null;

            while(eventType != XmlPullParser.END_DOCUMENT) {
                switch (eventType) {
                    case XmlPullParser.START_TAG:
                        String startTag = parser.getName();
                        if(startTag.equals("student")) {
                            student = new Student();
                        }
                        if(startTag.equals("name")) {
                            student.setName(parser.nextText());
                        }
                        if(startTag.equals("age")) {
                            student.setAge(parser.nextText());
                        }
                        if(startTag.equals("address")) {
                            student.setAddress(parser.nextText());
                        }
                        break;
                    case XmlPullParser.END_TAG:
                        String endTag = parser.getName();
                        if(endTag.equals("student")) {
                            arrayList.add(student);
                        }
                        break;
                }
                eventType = parser.next();
            }


        }catch(XmlPullParserException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return arrayList;
    }
