如何縮放和保存查看SD卡

我有一個View現在我試圖將它保存爲修復大小例如500*666到sdcard。圖像保存成功，但圖像保存如下。圖像保存爲整個圖像的角落請參閱附加圖像。如何縮放和保存查看SD卡

代碼：

private void onSave(final View v) { 
v.setMinimumWidth(500); 
     v.setMinimumHeight(666); 
Bitmap viewBitmap_save = null; 

          savingdialog(); 
          DisplayMetrics dm = new DisplayMetrics(); 
          getWindowManager().getDefaultDisplay().getMetrics(
            dm); 
          Display display = getWindowManager() 
            .getDefaultDisplay(); 

          viewBitmap_save = Bitmap.createBitmap(500, 666, 
            Bitmap.Config.ARGB_8888);// i 
          Canvas canvas = new Canvas(viewBitmap_save); 
          v.draw(canvas); 
          try { 
           Random randomGenerator = new Random(); 
           long RANDOMFILENUMBER = randomGenerator 
             .nextLong(); 
           File wallpaperDirectory = new File(
             "/sdcard/Image Telling/"); 
           // have the object build the directory 
           // structure, if needed. 
           wallpaperDirectory.mkdirs(); 
           // create a File object for the output file 

           // FileOutputStream outStream = new 
           // FileOutputStream(file); 
           File outputFile = new File(wallpaperDirectory, 
             RANDOMFILENUMBER + ".png"); 
           FileOutputStream outStream = new FileOutputStream(
             outputFile); 
           viewBitmap_save.compress(CompressFormat.PNG, 
             100, outStream); 

           sendBroadcast(new Intent(
             Intent.ACTION_MEDIA_MOUNTED, 
             Uri.parse("file://" 
               + Environment 
                 .getExternalStorageDirectory()))); 

          } catch (Exception e) { 
           // TODO: handle exception 
          } 
}

我給寬和高的修復，因爲我需要的圖像作爲固定大小。如何縮放查看？請幫幫我。
