The first gif is what i have now, and the second on is what i want to get.

The code works but the textview which displays song current position is only updating when i stop dragging, but i want it to update when im dragging it.

Check out the gifs i posted in the link so you understand what i want to achieve.

Thanks in advance,

Vince

updateProgressBar(); called when i change a song

My code

private Runnable mUpdateTime = new Runnable() {
@Override
public void run() {
long songCurrentTime = mediaPlayer.getCurrentPosition();
long songTotalTime = mediaPlayer.getDuration();

tvSongCurrentTime.setText(""+utilities.msToTimer(songCurrentTime));
tvSongTotalTime.setText(""+utilities.msToTimer(songTotalTime));

int progress = (int)(utilities.getProgressPercentage(songCurrentTime, songTotalTime));
seekBar.setProgress(progress);

mHandler.postDelayed(this, 100);
}
};

public void updateProgressBar(){
mHandler.postDelayed(mUpdateTime, 100);
}

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean
fromUser) {

}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
mHandler.removeCallbacks(mUpdateTime);
}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
mHandler.removeCallbacks(mUpdateTime);
int songTotalTime = mediaPlayer.getDuration() ;
int currentPosition = utilities.progressToTimer(seekBar.getProgress(),
songTotalTime);

mediaPlayer.seekTo(currentPosition);
updateProgressBar();
}

You should do it in 'onProgressChanged' method. Like this :

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean
fromUser) {
if(fromUser)
//myTextView.setText("" + progress);
updateProgressBar();
}


Follow the below code. It may help you.

final TextView sometextview=findViewById(R.id.someid);//your textview
sometextview.setText("Hello Android");

final SeekBar seekbar=(SeekBar) findViewById(R.id.someseekbar); //your seekbar
seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { //listener for your seekbar

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}

@Override
public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {
// TODO Auto-generated method stub

sometextview.setTextSize(progress+"%");//Here is the textview with the progress number.

}
});
