Hello,
I have created a MediaPlayer and will play a sound file. There is also
a ProgressBar which I've configured to be a Horizontal Progress Bar.
The problem I'm having is getting the progress bar to update as the
song plays, i.e. when the song is half way played I want the progress
bar to be half way filled.
I can see that the trick is to use some sort of sleeping thread that
wakes up and then performs the ProgressBar.setProgress
(MediaPlayer.getCurrentPosition()) code but I cannot factor in the
threading code.
Would someone please take a look at a simple version of my code that
uses a button to manually update the progress bar and please help to
set me on the right course. Threads have never been my strong suit :(
Thanks in advance guys.
public class musicPlayer extends Activity {
private Button buttonPlay;
private MediaPlayer mp = new MediaPlayer();
private ProgressBar progressMusic;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initialiseSong();
//Create Play Button
buttonPlay = (Button) findViewById(R.id.buttonPlay);
buttonPlay.setOnClickListener(new OnClickListener(){
public void onClick(View v){
playSong();
}
});
progressMusic = (ProgressBar) findViewById
(R.id.progressMusic);
progressMusic.setProgress(0);
progressMusic.setMax(mp.getDuration());
final Button buttonIndex = (Button) findViewById
(R.id.buttonIndex);
buttonIndex.setOnClickListener(new OnClickListener(){
public void onClick(View v){
progressMusic.setProgress(mp.getCurrentPosition());
}
});
}
//Creates the player with a default song selected.
private void initialiseSong(){
mp = MediaPlayer.create(this, R.raw.cake);
}
private void playSong(){
if(mp.isPlaying()){
mp.pause();
buttonPlay.setText("Resume");
}else{
mp.start();
buttonPlay.setText("Pause");
}
}
}
