You have to just update the onProgressChanged method as follows.

int yourStep = 25;
public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
progress = ((int)Math.round(progress/yourStep ))*yourStep;
seekBar.setProgress(progress);
textview.setText(progress + "");

}

Hope its help

UPD

I think in your xml you set android:max="100" for your SeekBar. But you need to set android:max="101", because between 0 and 100 = 101 point's.

just replace

android:max="100"

for

android:max="101"

Try this:

seekBar.setProgress(4);

This will give the values, 0, 1, 2, 3, 4. You don't need to be playing about with onProgressChanged, simply multiply by 25 and you have the values 0, 25, 50, 75, 100.

Try the following code.

seekBar.setProgress(YOUR_VALUE);
