Fire events at specific at specific progress as the seek bar progresses Android

Question

I followed this tutorial to create an audio player.

Now I want to add some events that fires events when the player reaches a specific progress. For example, at 00:32 of the current audio, display a Toast.

The interface should look like this :

The white dots represents the events in this case. Any idea?

I found it guys, here is my code (that worked perfectly)

private ImageView CreateWhiteDot(int time) {
    ImageView WhiteDot = new ImageView(getApplicationContext());
    float x = 0;
    float y = 0;
    WhiteDot.setImageResource(R.drawable.stop_dot_inactive);
    x = sbStopPlayerSlider.getX() + 15;
    x += ((sbStopPlayerSlider.getWidth() - 30) * time * 1000)
            / mpAudioPlayer.getDuration();
    WhiteDot.setX(x);
    y = sbStopPlayerSlider.getTranslationY()
            + sbStopPlayerSlider.getHeight() / 2;
    WhiteDot.setY(y);
    return WhiteDot;
}
