POWeird animation on Gallery when a invalidate is requested from it's children
text
Body
copied!<p>This is the adapter of my Gallery on which I display ImageViews (thumb of a page)</p> <p>I want to load the images ASync (some times this can come from Network), so I did that code:</p> <pre><code> public View getView(int position, View convertView, ViewGroup parent) { final ImageView image = convertView != null ? convertView : new ImageView(getContext()); final PageInfo page = getItem(position); image.setBackgroundColor(Color.WHITE); image.setLayoutParams(new Gallery.LayoutParams(96, 170)); new AsyncTask<Void, Void, Bitmap>() { @Override protected Bitmap doInBackground(Void... arg0) { try { File thumbnail = page.thumbnail();//Thumbnail download the image if not available return BitmapFactory.decodeStream(new FileInputStream(thumbnail)); } catch (ApplicationException e) { return null; } catch (NetworkException e) { return null; } } protected void onPostExecute(Bitmap result) { if (result == null) return; image.setImageBitmap(result); }; }.executeOnExecutor(executor); return image; } </code></pre> <p>This works, but if I'm dragging the Gallery the views (when switching to the real Bitmap) do a "jump" to another position inside the galley, making it weird.</p> <p>How can I avoid that? Or can I change the image of a ImageView without requesting layout of the ViewGroup?</p> <p>EDIT: A similar question on Google dev groups <a href="http://code.google.com/p/android/issues/detail?id=15526" rel="nofollow">http://code.google.com/p/android/issues/detail?id=15526</a></p>
