i am working on my first project with android and java
and have very little experience.
i have a radio player (start and stop button that activates a service)
and
some data from a xml file like artist title and album loaded in a textview
i use a timer so that the gui updates with the song played
this all works
only when the lyrics are loaded in the textview it only shows the first line of the xml tag <LYRIC>
this is my main activity:
extends Activity implements OnClickListener{
private static final String TAG = "ServicesDemo";
public String myimageURL;
private EditText Lyrics;
private ImageView AlbumPic;
private Button play, stop;
private TextView Artist, Song, Album, News, Lyric;
private UpdateTimeTask m_updateTime;
private Handler m_handler;
Parser data;
/** The delay in milliseconds between updates. */
private final int DELAY = 20000;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Artist =(TextView)findViewById(R.id.tvArtist);
Song =(TextView)findViewById(R.id.tvSongTitle);
Album =(TextView)findViewById(R.id.tvAlbum);
play = (Button) findViewById(R.id.play);
stop = (Button) findViewById(R.id.stop);
Lyrics = (EditText) findViewById(R.id.tvLyrics);
News = (TextView)findViewById(R.id.tvAnouncement);
AlbumPic = (ImageView) findViewById(R.id.AlbumPic);
play.setOnClickListener(this);
stop.setOnClickListener(this);
m_updateTime = new UpdateTimeTask();
m_handler = new Handler();
m_handler.post(m_updateTime);
}
private class UpdateTimeTask implements Runnable {
public void run() {
try {
SAXParserFactory saxPF = SAXParserFactory.newInstance();
SAXParser saxP = saxPF.newSAXParser();
XMLReader xmlR = saxP.getXMLReader();
URL url = new URL("http://www.mysite.com/AndroidTest.php");
XMLHandler myXMLHandler = new XMLHandler();
xmlR.setContentHandler(myXMLHandler);
xmlR.parse(new InputSource(url.openStream()));
} catch (Exception e) {
System.out.println(e);
}
data = XMLHandler.data;
for (int i = 0; i < data.getTitle().size(); i++) {
Lyrics.setText(data.getLyric().get(i));
myimageURL = data.getPic().get(i);
Song.setText("Title = "+data.getTitle().get(i));
Artist.setText("Artist = "+data.getArtist().get(i));
Album.setText("Album = "+data.getAlbum().get(i));
}
downloadFile(myimageURL );
}
Bitmap bmImg;
void downloadFile(String fileUrl) {
URL myFileUrl = null;
try {
myFileUrl = new URL(fileUrl);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
HttpURLConnection conn = (HttpURLConnection) myFileUrl
.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is);
AlbumPic.setImageBitmap(bmImg);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
m_handler.postDelayed(m_updateTime, DELAY);
AlbumPic.clearAnimation();
}
}
my xml code
<?xml version="1.0"?>
<CATALOG>
<CD>
<LYRIC>Stop that train: I'm leavin' - today!
Stop that train: I'm leavin' - anyway!
Stop that train: I'm leavin'. and I said:
It won't be too long whether I'm right or wrong;
I said, it won't be too long whether I'm right or wrong.
All my good life I've been a lonely man,
Teachin' my people who don't understand;
And even though I tried my best,
I still can't find no happiness.
So I got to say:
Stop that train: I'm leavin' - oh, baby now!
Stop that train: I'm leavin' - don't care what you say!
Stop that train: I'm leavin'. and I said:
It won't be too long whether I'm right or wrong;
Said, it won't be too long whether I'm right or wrong.
Some goin' east; and-a some goin' west,
Some stand aside to try their best.
Some livin' big, but the most is livin' small:
They just can't even find no food at all.
I mean, stop it:
Stop that train: I'm leavin' - leavin', mm-hmm.
Stop that train: I'm leavin' - I don't mind!
Stop that train: I'm leavin'. and I said:
It won't be too long whether I'm right or wrong;
I said it won't be too long whether I'm right or wrong.
Stop that train: I'm leavin' - leavin'!
Stop that train: I'm leavin' - can't take it!
Stop that train: I'm leavin' - got to be better!
It won't be too long whether I'm right or wrong;
I said it won't be too long whether I'm right or wrong.</LYRIC>

I advice you to check you XMLHandler object. I suspect you have something wrong there.
If you can show us your XMLHandler class that would be better to help you.
EDIT:
I have made some changes to your handler. I think you might have a problem when you read the element value. Use a CharArrayWriter instead (I’ve resolve an identical problem with that).
And I think you doesn’t need the ‘elementOn’ too. If its a non necessary variable just don’t use it.
Make sure you have too a multine TextView defined on your XML layout.
Hope it works 🙂
