Seekbar改變int的值

Question

我有一個seekbar，並且想要設置它以便它會改變我的doBrightness方法的int值，所以當你滑動seekbar時，它會改變圖像的亮度。

這裏是doBrightness方法的開始，我想從搜索條修改int值：

我怎麼能做到這一點？

public Bitmap doBrightness(Bitmap src, int value) { 
      ..................... 
    } 

這裏搜索條我已經設置了：

sb = (SeekBar)v.findViewById(R.id.seekBar1); 

    sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { 

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

     } 

     @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 


      sb.setProgress(0); 
      sb.setMax(100); 

      //Change the int value of the doBrightness from here? 
     } 
    }); 

Answer 1

sb = (SeekBar)v.findViewById(R.id.seekBar1); 
sb.setProgress(0); 
sb.setMax(100); 

sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { 

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

    } 

    @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 

     //doBrightness change here 
    } 
});
