How do I parse and display things from an XML in an Android application?

Question

The XML file I want to parse is

<?xml version="1.0" encoding="utf-8"?>
<items>
    <item>
        <question>Question?</question>
        <answer1>Answer 1 is fun</answer1>
        <answer2>Answer 2 is too</answer2>
        <answer3>Answer 3 is me</answer3>
        <answer4>Answer 4 no more</answer4>
        <correctanswer>Answer 1 is fun</correctanswer>

    </item>
</items>

The code I have written so far may or may not be completely off. This is my first time writing a parser like this. I've been told there are many ways so please if there are other suggestions, feel free to let me know! :)

 package assinment1.sfapps.com.myapplication; import android.app.Activity; import android.content.res.Resources; import android.content.res.XmlResourceParser; import android.os.Bundle; import android.view.MenuItem; import android.widget.TextView; import org.xmlpull.v1.XmlPullParser; import org.xmlpull.v1.XmlPullParserException; import java.io.IOException; import java.util.ArrayList; class question { public String question; public String answer1; public String answer2; public String answer3; public String answer4; public String comment; public String correctAnswer; } public class TriviaGame extends Activity { ArrayList<question> questions; question q; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_trivia_game); TextView myXmlContent = (TextView)findViewById(R.id.tvfun); String stringXmlContent; try { stringXmlContent = getEventsFromAnXML(this); myXmlContent.setText(stringXmlContent); } catch (XmlPullParserException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private String getEventsFromAnXML(Activity activity) throws XmlPullParserException, IOException { //StringBuffer stringBuffer = new StringBuffer(); Resources res = activity.getResources(); XmlResourceParser xpp = res.getXml(R.xml.questions_q); xpp.next(); int eventType = xpp.getEventType(); while (eventType != XmlPullParser.END_DOCUMENT) { q = new question(); if(eventType == XmlPullParser.START_DOCUMENT || (xpp.getName() == "items" || xpp.getName() == "item" )) { // stringBuffer.append("--- Start XML ---"); } else if(eventType == XmlPullParser.START_TAG) { if(){ } if(xpp.getName() == "question"){ q.question = xpp.getText(); }else if(xpp.getName() == "answer1"){ q.answer1 = xpp.getText(); }else if(xpp.getName() == "answer2"){ q.answer2 = xpp.getText(); }else if(xpp.getName() == "answer3"){ q.answer3 = xpp.getText(); }else if(xpp.getName() == "answer4"){ q.answer4 = xpp.getText(); }else if(xpp.getName() == "comment"){ q.comment = xpp.getText(); }else if(xpp.getName() == "correctAnswer"){ q.correctAnswer = xpp.getText(); } questions.add(q); // stringBuffer.append("\\nSTART_TAG: "+xpp.getName()); } eventType = xpp.next(); } return q.toString(); } private void printQ(ArrayList<question> questions) { //findViewById() } @Override public boolean onOptionsItemSelected(MenuItem item){ // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id=item.getItemId(); //noinspection SimplifiableIfStatement if(id==R.id.action_settings){ return true; } return super.onOptionsItemSelected(item); } } 

Any help would be amazing. I do know that this code is unfinished.. It also crashes. I am trying to store the questions I take out of the XML in the array list I created. I am also trying to make sure this will store multiple questions. Thank you very much for even looking at this haha.

Answer 1

I think in your case it is more convenient to work with objects, and answers save in array, then you can have any number answers
use simple-xml

Answer 2

MyQs is a global array in my case.
How to get the questions from the XML (this case stored in array).. if you need a none allocated try an ArrayList.

 public void getQuestionsfromXML() throws XmlPullParserException,
            IOException {
        String tagname = " ";
        XmlResourceParser xpp = getResources().getXml(R.xml.trivia);

        if (xpp == null) {

        } else {
            xpp.next();
            int eventType = xpp.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                if (eventType == XmlPullParser.START_TAG) {
                    tagname = xpp.getName();
                } else if (eventType == XmlPullParser.TEXT) {
                    setNextQuestion(tagname, xpp.getText());

                }
                eventType = xpp.next();

            }
        }
    }

 public void setNextQuestion(String tagname, String textin) {

        if (tagname.equals("question")) {
            myQs[myQsindex] = new myQuestion();
            myQs[myQsindex].Question = textin;

        }
        if (tagname.equals("answer1")) {
            myQs[myQsindex].Answer1 = textin;

        }
        if (tagname.equals("answer2")) {
            myQs[myQsindex].Answer2 = textin;

        }
        if (tagname.equals("answer3")) {
            myQs[myQsindex].Answer3 = textin;

        }
        if (tagname.equals("answer4")) {
            myQs[myQsindex].Answer4 = textin;

        }
        if (tagname.equals("correctanswer")) {
            myQs[myQsindex].correctAnswer = textin;

        }

        if (tagname.equals("comment")) {
            myQs[myQsindex].comment = textin;
            msg = "question-> " + myQs[myQsindex].Question + "\n" + "Answer:     " + myQs[myQsindex].correctAnswer + "Index: " + myQsindex;

            if (TotalNumberofQs < maxQs)// precaution here
            {
                myQsindex++;
                TotalNumberofQs++;
            }
        }

Displaying it is obviously much more code but the basic idea is
take the following code and use it to update the question whenever needed.

    private void displayQuestion() {
            //Text View
            question.setText(myQs[myQsindex].Question);

            //Text View Radio buttons
            Answer1.setText(myQs[myQsindex].Answer1);
            Answer2.setText(myQs[myQsindex].Answer2);
            Answer3.setText(myQs[myQsindex].Answer3);
            Answer4.setText(myQs[myQsindex].Answer4);
            correctAnswer = myQs[myQsindex].correctAnswer;
    }
