Android'de yüzey görünümü ile birlikte görüntü nasıl kaydedilir? i butonuna tıklayın resimle birlikte

Question

Yüzey i sadece yüzeyi elde bu kodla kod

camera.takePicture(shutterCallback, rawCallback, jpegCallback); 
ShutterCallback shutterCallback = new ShutterCallback() 
{ 
    public void onShutter() 
    { 
     Log.d(TAG, "onShutter'd"); 
    } 
}; 

PictureCallback rawCallback = new PictureCallback() 
{ 
    public void onPictureTaken(byte[] data, Camera camera) 
    { 
     Log.d(TAG, "onPictureTaken - raw"); 
    } 
}; 

PictureCallback jpegCallback = new PictureCallback() 
{ 
    public void onPictureTaken(byte[] data, Camera camera) 
    { 
     try 
     { 
      File root = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM),"Camera"); 
      if (!root.exists()) 
      { 
       root.mkdirs(); 
      } 

      FileOutputStream f = new FileOutputStream(new File(root,System.currentTimeMillis()+".jpg")); 
      int len1 = data.length; 
      f.write(data,0, len1); 
      f.close(); 
     } 
     catch (Exception e) 
     { 
      e.printStackTrace(); 
     } 
     finally 
     { 
     } 
    } 
}; 

aşağıdaki çalıştı bunun için sadece yüzeyi tasarruf var, resimle birlikte yüzeyini kurtarmak için herhangi bir olası var mı? Herhangi biri biliyorsa lütfen bana yardım edin
