Seekbar setMax

android_seekbar_min_max.java

//You cannot set the min value of a SeekBar (always 0) and you cannot set the step value of a SeekBar (always 1).
//If you want to set the value from 60 to 180 with a step of 1 this is the way to do it 
//From http://stackoverflow.com/questions/20762001/how-to-set-seekbar-min-and-max-value

int step = 1;
int max = 180;
int min = 60;

// Ex : 
// If you want values from 3 to 5 with a step of 0.1 (3, 3.1, 3.2, ..., 5)
// this means that you have 21 possible values in the seekbar.
// So the range of the seek bar will be [0 ; (5-3)/0.1 = 20].
seekbar.setMax( (max - min) / step );


seekbar.setOnSeekBarChangeListener(

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {}

        @Override

        public void onProgressChanged(SeekBar seekBar, int progress, 
            boolean fromUser) 
        {
            // Ex :
            // And finally when you want to retrieve the value in the range you
            // wanted in the first place -> [3-5]
            //
            // if progress = 13 -> value = 3 + (13 * 0.1) = 4.3
            double value = min + (progress * step);
