Android SeekBar doesn't refresh after dynamically setting max value with setMax

Question

I am using the stock SeekBar component to navigate through a set of ViewPagers and it's working quite fine. Only problem is that when the data changes, I have to dynamically change the max value of the SeekBar via setMax(int value). When I do that, the SeekBar does not get updated until I navigate to a new page. I have a hacky fix in place where I do this, to force a onProgressChanged:

seekBarVP.setProgress(focusedPage+1);
seekBarVP.setProgress(focusedPage-1);
seekBarVP.setProgress(focusedPage);

Is there a better way to do this?

Answer 1

Create updateThumb(); method in VerticalSeekbar

public void updateThumb(){
     onSizeChanged(getWidth(), getHeight(), 0, 0);
}

And then call update thumb method after setting progress.

seekBar.setProgress((int) progress);
seekBar.updateThumb();

its work for me in verticalseekbar calss
