Я хотел бы собрать все результаты в ArrayList, выполнить итерацию в этом массиве и отобразить результат, но когда я пытаюсь запустить приведенный ниже код, он возвращает только один элемент ...
У меня есть 3 класса ...
public class XMLDataCollected {
ArrayList<String> names = new ArrayList<String>();
ArrayList<String> vicinities = new ArrayList<String>();
ArrayList<String> types = new ArrayList<String>();
ArrayList<String> lats = new ArrayList<String>();
ArrayList<String> longs = new ArrayList<String>();
String name = null;
String vicinity = null;
String type = null;
String lat = null;
String longi = null;
public ArrayList<String> getName() {
return names;
}
public void setName(String name) {
this.names.add(name);
this.name = name;
Log.i("This is the name: ", name + "size: " + names.size());
}
public ArrayList<String> getVicinity() {
return vicinities;
}
public void setVicinity(String vicinity) {
this.vicinities.add(vicinity);
this.vicinity = vicinity;
Log.i("This is the vicinity: ", vicinity);
}
public ArrayList<String> getType() {
return types;
}
public void setType(String type) {
this.types.add(type);
this.type = type;
Log.i("This is the type: ", type);
}
public ArrayList<String> getLat() {
return lats;
}
public void setLat(String lat) {
this.lats.add(lat);
this.lat = lat;
Log.i("This is the latitude: ", lat);
}
public ArrayList<String> getLongi() {
return longs;
}
public void setLongi(String longi) {
this.longs.add(longi);
this.longi = longi;
Log.i("This is the longitude: ", longi);
}
public String populate(){
StringBuilder sb = new StringBuilder();
sb.append(getName());
sb.append(getVicinity());
sb.append(getType());
sb.append(getLat());
sb.append(getLongi());
return sb.toString();
}

public class HandlingXMLStuff extends DefaultHandler {
String elementValue = null;
Boolean elementOn = false;
XMLDataCollected data;
public ArrayList<String> getData() {
return data.getName();
}
@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
// TODO Auto-generated method stub
elementOn = true;
if (localName.equals("result")) {
data = new XMLDataCollected();
} else if (localName.equals("CD")) {
}
}
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
elementOn = false;
/**
* Sets the values after retrieving the values from the XML tags

if (localName.equalsIgnoreCase("name"))
data.setName(elementValue);
else if (localName.equalsIgnoreCase("vicinity"))
data.setVicinity(elementValue);
else if (localName.equalsIgnoreCase("type"))
data.setType(elementValue);
else if (localName.equalsIgnoreCase("lat"))
data.setLat(elementValue);
else if (localName.equalsIgnoreCase("lng"))
data.setLongi(elementValue);
}
@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
// TODO Auto-generated method stub
if (elementOn) {
elementValue = new String(ch, start, length);
elementOn = false;
}
}
}
3.
public class XMLParsingActivity extends Activity implements OnClickListener {
static final String baseURL = "http://www.google.com/ig/api?weather=";
static final String test = "";
TextView tv;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button bone = (Button) findViewById(R.id.btnone);
tv = (TextView) findViewById(R.id.tvWeather);
bone.setOnClickListener(this);
}
public String buildURL(int lat, int longi){
String url = "";
return url;
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
try{
URL website = new URL(test);
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
HandlingXMLStuff doingWork = new HandlingXMLStuff();
XMLDataCollected xdc = new XMLDataCollected();
xr.setContentHandler(doingWork);
xr.parse(new InputSource(website.openStream()));
StringBuilder sb = new StringBuilder();
String name = null;
for(int index = 0; index < doingWork.getData().size(); index++){
sb.append(doingWork.getData().get(index));
Log.i("test","" + index);
}
// tv.setText("Name: " + name + "\n" + "Vicinity: " + vicinity + "\n" + "Type: " + type + "\n "
// + "Latitude: " + lat + "\n " + "Longitude: " + longi
// );
tv.setText("The size: " + sb);
}catch(Exception ex){
tv.setText("Error" + ex.toString());
}
}
}
Это образец XML-файла ...

Здесь я хочу добиться итерации в результате, но в массиве результатовимеет только один элемент ... пожалуйста, помогите мне ...
