GridView à l'intérieur de la liste déroulante dans android

Je veux mettre un gridview avec des images à l'intérieur d'une liste extensible...j'ai déjà faire, mais la gridview ne montrent pas tous les éléments...

Comment puis-je faire ma liste extensible à l'enfant de s'adapter à la gridview taille?
