Android - parser

step-3:

package com.ram.parser;

public class FeedParserFactory {

static String feedUrl = "";
public FeedParserFactory(String url){

feedUrl=url;

}
public FeedParser getParser(){
return getParser(ParserType.XML_PULL);
}

public FeedParser getParser(ParserType type){
switch (type) {
case XML_PULL:
return new XmlPullFeedParser(feedUrl);

default:
return null;
}

}
}



step-4:

package com.ram.parser;

import java.util.List;


public interface FeedParser {

void parse(ParserCallback details);

}

step-2:

package com.ram.parser;
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;


public abstract class BaseFeedParser implements FeedParser {

private final URL feedUrl1;

protected BaseFeedParser(String feedUrl){
try {
this.feedUrl1 = new URL(feedUrl);
} catch (MalformedURLException e) {
throw new RuntimeException("BasefeedParser wrong url /n"+e);
}
}

protected InputStream getInputStream() {
try {
System.out.println("url-- "+feedUrl1);
return feedUrl1.openConnection().getInputStream();
} catch (IOException e) {
throw new RuntimeException("connection failed IO exp "+e);
}

}
}

step-5:

package com.ram.parser;

import java.util.ArrayList;
import java.util.List;

import org.xmlpull.v1.XmlPullParser;

import android.util.Log;
import android.util.Xml;

public class XmlPullFeedParser extends BaseFeedParser {

public void parse(final ParserCallback callback) {

new Thread(){

while(keepGoing){

XmlPullParser parser = Xml.newPullParser();
try {
parser.setInput(getInputStream(), null);
System.out.println("Parser Data--------------\n------"+parser.getText());
int eventType = parser.getEventType();
message currentMessage = null;
boolean done = false;
while (eventType != XmlPullParser.END_DOCUMENT && !done){
String name = null;
switch (eventType){

}
eventType = parser.next();
}
} catch (Exception e) {

//throw new RuntimeException(e);

//return messages;
System.out.println("Pass ctrl 2 Main");
callback.parseDidFinish(messages);

}
}
}.start();
}


@Override
public List parse() {
// TODO Auto-generated method stub
return null;
}
}

step-6:

package com.ram.parser;

import java.util.List;


public interface ParserCallback {
public void parseDidFinish(List messages);


}

step-7:

package com.ram.parser;
/**

public enum ParserType{
