comment obtenir la position actuelle dans FragmentPagerAdapter?

J'ai un adaptateur qui s'étend FragmentPagerAdapter et prend avantage de la SCI style actionBar. Ce actionbar a des actions qui prennent en entrée à partir de la page actuellement sélectionnée.

Précisément, j'ai une capture d'écran de l'icône dans l'actionbar qui prend l'url de la page en cours et affiche toutes les captures d'écran de cette url. Cependant, je ne sais pas comment faire pour récupérer la page actuellement sélectionnée.

Comment puis-je mettre en place quelque chose comme un

    public int getActivePage() {
       return position;

Im encore à travailler sur le viewpager mise en œuvre, de sorte que mon code est encore fortement tributaire des exemples, afin de mépris le désordre 😛

Le problème des zones sont indiquées ci-dessous.
