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! :)

}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.
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;
}
