如何将BitmapDrawable设置到ImageView中？

Question

tapimageview是ImageView，我想要显示mBitmapDrawable一旦我点击保存图像。我做对了吗？

save.setOnClickListener(new View.OnClickListener() { 
     @SuppressWarnings("deprecation") 
     public void onClick(View v) { 
      Log.v(TAG, "Save Tab Clicked"); 
      viewBitmap = Bitmap.createBitmap(500, 500, Bitmap.Config.ARGB_8888);//i is imageview whch u want to convert in bitmap 
      canvas = new Canvas(viewBitmap); 
      tapimageview.draw(canvas); 
      canvas.drawBitmap(bmp, 0, 0, paint); 
      canvas.drawBitmap(drawingBitmap, matrix, paint); 
      canvas.drawBitmap(bmpstickers, matrix, paint); 
      try { 
       mBitmapDrawable = new BitmapDrawable(viewBitmap); 
       tapimageview.setImageMatrix(mBitmapDrawable); 
       mCurrent = "PXD_" + new SimpleDateFormat("yyyyMMdd_HHmmss", 
       Locale.getDefault()).format(new Date()) + ".jpg"; 

       mNewSaving = ((BitmapDrawable) mBitmapDrawable).getBitmap(); 
       String FtoSave = mTempDir + mCurrent; 
       File mFile = new File(FtoSave); 
       mFileOutputStream = new FileOutputStream(mFile); 
       mNewSaving.compress(CompressFormat.JPEG, 100, mFileOutputStream); 
       mFileOutputStream.flush(); 
       mFileOutputStream.close(); 
      } 
      catch (FileNotFoundException e) { 
       Log.v(TAG, "FileNotFoundExceptionError " + e.toString()); 
      } 
      catch (IOException e) { 
       Log.v(TAG, "IOExceptionError " + e.toString()); 
      } 
     } 
    }); 
}
