        for(int i = 0; i < items.length; i++){
            Card c = new Card(this);
            //add header

If I change to CardListView, it will be right. So why CardGridView not works. Thanks for help.

Hi Gabriele, I try this example. http://java.dzone.com/articles/be-lazy-productive-android-2 https://github.com/PareshMayani/CardslibDemo

    It works using CardListView, but if I change to CardGridView, the images will not show. The same problems as mine.
