I had it working until i tried to combine it with xml that is parsed from my webpage. No markers get added, yet i get no errors. Below is the new code. Any help is greatly appreciated!
LocationBasedServicesV2.java :
private MapView myMap;
private TextView tv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView) findViewById(R.id.tv);
try {
URL url = new URL("MySiteGoesHere");
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
ExampleHandler myExampleHandler = new ExampleHandler();
xr.setContentHandler(myExampleHandler);
xr.parse(new InputSource(url.openStream()));
ParsedExampleDataSet parsedExampleDataSet = myExampleHandler.getParsedData();
tv.setText(parsedExampleDataSet.toString());
} catch (Exception e) {
new AlertDialog.Builder(this)
.setMessage(e.toString())
.setTitle("error")
.setCancelable(true)
.setNeutralButton(android.R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton){}
})
.show();
}
initMap();
//initLocationManager();
}
private void initMap() {
myMap = (MapView) findViewById(R.id.mymap);
View zoomView = myMap.getZoomControls();
LinearLayout myzoom = (LinearLayout) findViewById(R.id.myzoom);
myzoom.addView(zoomView);
myMap.displayZoomControls(true);
}
/*private void initLocationManager() {

One thing to check: your method createAndShowMyItemizedOverlay() appears to be only called when the ParsedExampleDataSet is created – and this is created in a try/catch where you’re swallowing any exception. This could be the reason why your not seeing an error and why it stopped working when you started trying to parse the xml.
