How to set seekbar min and max value

I have a seekbar and trying to set the value from 60 to 180 for one and 40 to 190 for the second one in step of 1.

sb1 = (SeekBar) findViewById(R.id.progresss);
        sb1.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {       

            @Override       
            public void onStopTrackingTouch(SeekBar seekBar) {      
                // TODO Auto-generated method stub
                //int inVal = Integer.parseInt(String.valueOf(seekBar.getProgress()));
                //inVal =+ 70;
                //Toast.makeText(getApplicationContext(), String.valueOf(inVal),Toast.LENGTH_LONG).show();
            }       

            @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
                progress =+ 70;
                Toast.makeText(getApplicationContext(), String.valueOf(progress),Toast.LENGTH_LONG).show();

            }       
        });

is not working. Any idea how to fix it?

Solution

You cannot set the min value of a SeekBar (always 0) and you cannot set the step value of a SeekBar (always 1).

To set the value from 60 to 180 with a step of 1:

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(
    new OnSeekBarChangeListener()
    {
        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {}

        @Override
        public void onStartTrackingTouch(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);

        }
    }
);

I put another example within the code so that you understand the math.
