Parsing local gpx file in Android

Question

I followed this example to parse a local GPX file in Android: http://android-coding.blogspot.pt/2013/01/get-latitude-and-longitude-from-gpx-file.html

All works fine to access "lat" and "long" but I need also to get the "ele" value but all my tentatives were unsuccessful. Anyone can give me some hits to do that?

Thanks in advance! Best regards, NR.

I will add my library for GPX parsing to these answers: https://github.com/ticofab/android-gpx-parser. It provides two ways to parse you GPX file: once you obtain / create a GPXParser object (mParser in the examples below), you can then either parse directly your GPX file

Gpx parsedGpx = null;
try {
    InputStream in = getAssets().open("test.gpx");
    parsedGpx = mParser.parse(in);
} catch (IOException | XmlPullParserException e) {
    e.printStackTrace();
}
if (parsedGpx == null) {
    // error parsing track
} else {
    // do something with the parsed track
}

or you can parse a remote file:

mParser.parse("http://myserver.com/track.gpx", new GpxFetchedAndParsed() {
    @Override
    public void onGpxFetchedAndParsed(Gpx gpx) {
        if (gpx == null) {
            // error parsing track
        } else {
            // do something with the parsed track
        }
    }
});
