Commutateur de classe de gonflage Erorr, ActionBarSherlock (InflateException)

Question

Donc, je me heurte à une erreur. J'ai une SherlockFragmentActivity, et au moins deux SherlockFragments. Les deux utilisent onCreateView pour gonfler un fichier xml. LoginFragment, cependant, a un widget de commutation: le fragment econ ne le fait pas. Si j'ajoute un widget switch dans econfragment.xml, cela provoque un plantage du même type (alors que loginfragment est mis en commentaire hors implémentation). Si je supprime le widget de commutateur de loginfragment, une erreur similaire s'affiche pour RadioGroup - mais econfragment possède déjà un groupe radio et ne génère aucune erreur. Voici le code correspondant:

    </ScrollView> 

Y at-il quelque chose que je devrais faire fondamentalement différemment? Je devrais noter que cette erreur seulement se produit sur Gingerbread ou inférieur - il fonctionne parfaitement bien sur ICS, par exemple. Le but de mon utilisation de l'ABS est d'obtenir la rétrocompatibilité, donc je suis un peu interloqué avec cette erreur pour le moment!

Answer 1

http://developer.android.com/reference/android/widget/Switch.html

depuis: API Niveau 14

Le widget Switch a été introduit dans ICS.
