Discrete seekbar in Android app?

Question

I would like to create a seekbar for an Android app that allows the user to select a value between -5 and 5 (which maps to \"strongly disagree\" and \"strongly agree\"). How

I hope this code surely helpes you. Try this...

 float discrete = 0;
 float start = 0;
 float end = 100;
 float start_pos = 0;
 int start_position = 0;


 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);


     start = -10; //you need to give starting value of SeekBar 
     end = 10; //you need to give end value of SeekBar 
     start_pos = 5; //you need to give starting position value of SeekBar 

     start_position = (int)(((start_pos - start) / (end - start)) * 100);
     discrete = start_pos;
     SeekBar seek = (SeekBar) findViewById(R.id.seekBar1);
     seek.setProgress(start_position);
     seek.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {


         @Override
         public void onStopTrackingTouch(SeekBar seekBar) {
             // TODO Auto-generated method stub 
             Toast.makeText(getBaseContext(), "discrete = " + String.valueOf(discrete), Toast.LENGTH_SHORT).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 
             // To convert it as discrete value 
             float temp = progress;
             float dis = end - start;
             discrete = (start + ((temp / 100) * dis));

         }
     });
 }
