ListView

I have imported all the songs from my SD card to the list view.And now I want to select any song from that list view and play it in MediaPlayer.

What I have tried:

public class SongFile extends Activity implements AdapterView.OnItemClickListener {

private long id;
private String songtitle;
private String artist;

private ArrayList<songfile> songlist;
private ListView songListView;

private Cursor Musiccursor;

@Override
protected void onStart() {
super.onStart();
songListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView Intent intent = new Intent(getBaseContext(), MusicApp.class);
startActivity(intent);

}
});
}


public void getSongList(){
ContentResolver MusicResolver=getContentResolver();
Uri MusicUri= android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Musiccursor=MusicResolver.query(MusicUri,null,null,null,null);

if (Musiccursor != null && Musiccursor.moveToFirst()) {
int TitleColumn=Musiccursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
int idColumn=Musiccursor.getColumnIndex(MediaStore.Audio.Media._ID);
int artistColumn=Musiccursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);

do{
long thisID=Musiccursor.getLong(idColumn);
String thisTitle=Musiccursor.getString(TitleColumn);
String thisArtist=Musiccursor.getString(artistColumn);

songlist.add(new SongFile(thisID,thisTitle,thisArtist));

}while(Musiccursor.moveToNext());

}
}

@Override
public void onItemClick(AdapterView
}
}


//Player Class

public class MusicApp extends Activity implements View.OnClickListener {

ImageButton btnPlay,btnNext,btnPrev,btnPause;
MediaPlayer Mymedialayer;

@Override
public void onClick(View v) {

switch (v.getId()){
case R.id.btnPlay:
Mymedialayer.start();

break;
case R.id.btnPause:
Mymedialayer.pause();
Toast.makeText(getApplicationContext(), "Song is paused", Toast.LENGTH_SHORT).show();
break;
case R.id.btnNext:
break;
case R.id.btnPrev:
break;
}

}
