private SeekBar seekBar;

    setContentView(R.layout.main); 

    textView=(TextView)findViewById(R.id.radious); 
    seekBar=(SeekBar)findViewById(R.id.seekbar); 
    seekBar.setMax(90); 
    seekBar.setProgress(currentProgress); 
    textView.setText(String.valueOf(currentProgress)); 

    seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

      newProgressValue = seekBar.getProgress(); 
      currentProgress = newProgressValue ; 
      SharedPreferences.Editor editor = sharedPreferences.edit(); 
      editor.putInt(Key_PROGRESS, newProgressValue); 
      editor.commit(); 

     } 

     @Override 
     public void onStartTrackingTouch(SeekBar seekBar) { 
      // TODO Auto-generated method stub 

     } 

     @Override 
     public void onProgressChanged(SeekBar seekBar, int progress, 
       boolean fromUser) { 
      textView.setText(String.valueOf(seekBar.getProgress()));
