在布局中逐个添加 imageViews

Question

我想使用一个按钮添加一个图像，然后在一个指定的 relativeLayout 上显示缩略图。

public void showViewOfReceiptFromSelecting(String uriString)
     {
         byte[] imageData = null;
         try
         {
         InputStream fis = this.getContentResolver().openInputStream(Uri.parse((uriString)));
         Bitmap imageBitmap = BitmapFactory.decodeStream(fis);
         imageBitmap = Bitmap.createScaledBitmap(imageBitmap, 40, 40, false);
         ByteArrayOutputStream baos = new ByteArrayOutputStream();
         imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
         imageData = baos.toByteArray();
         ImageView image = new ImageView(this); 
         image.setImageBitmap(imageBitmap);
         image.setId(counterOfReceipts);
         RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
         rlp.addRule(RelativeLayout.RIGHT_OF, counterOfReceipts - 1);
         myRelalativelayout.addView(image, rlp);  // a relative Layout i already defined earlier in the code
         counterOfReceipts = counterOfReceipts + 1 ;
         }
         catch(IOException e) {
            e.printStackTrace();
         } 
     }

现在的问题是，当我试图再添加一个缩略图时，它就会取代了之前的那个旧的。我改怎么处理这个问题？

rlp属性是否是需要设置为ALIGN_WITH_PARENT_LEFT或者ALIGN_WITH_PARENT_RIGHT
