Avoiding the fade in effect after a ListView is refreshed

[a85]

I just started using the universal image loader library and have run into a really annoying problem. Everything loads well for the first shot but if anything changes in the data adapter the library initiates a fade in transition for every image in the list. Even though the images have been loaded already this is quite unnecessary. Is there something I am doing wrong?

The same applies for stub images. The stub image will be displayed and then the final image which creates this irritating flickering effect every time something in the list changes.

I guess getView(...) is called for every visible item after you changed adapter (you call notifyDataSetChanged(), don't you?). So .displayImage(...) is called again and so animation is applied again.

Show me your code - https://github.com/nostra13/Android-Universal-Image-Loader#user-support

Yes. That is pretty much it. I am guessing you could use a tag on the ImageView to avoid this. I am using this piece of code:

options = new DisplayImageOptions.Builder()
                        .showStubImage(R.drawable.photo_loading_background)
                        .displayer(new FadeInBitmapDisplayer(150)).build();
imageLoader.displayImage(thumbUrl, holder.thumb, options);

I think it's related to #149 and #126

I won't use a tag of ImageView because lib's user can re-assign it,I think you should use it for your needs, UIL can't help you with your problem.

Ok. Thanks for your help anyway.

Just found out that even disabling the fade in effect doesn't help on older devices. Any change in the adapter makes the library load stuff again making the app unusable.

[nostra13]

Did you try to use sample app? If you think it's also unusable then I can't help you. My library work this way.

[a85]

Well I implemented it as per the sample code. Any way, I have forked the repo and will fix it myself when I have the time. I have reverted my code to use an earlier library. Thanks for responding to the bug report as well as the code.
