android-在布局中逐個添加 imageViews

在布局中逐個添加 imageViews

我想使用一個按鈕添加一個圖像，然後在一個指定的 relativeLayout 上顯示縮略圖。

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();
         } 
     }

現在的問題是，當我試圖再添加一個縮略圖時，它就會取代了之前的那個舊的。我改怎麼處理這個問題？

最佳回答：

rlp屬性是否是需要設置為ALIGN_WITH_PARENT_LEFT或者ALIGN_WITH_PARENT_RIGHT
