Simple image listview Erreur NullPointerException

Question

J'essaie de créer une liste simple qui utilise des images et des chaînes personnalisées à partir d'un tableau de chaînes, mais quand je l'exécute, elle donne une exception de pointeur nul, disant que storage = null. Je ne suis pas sûr de ce qui se passe, j'ai triplé toutes les épellations des images etc ... et ne peux pas trouver quelque chose peut-être son causé dans le code? Pour les images j'ai créé un nouveau répertoire dans le dossier res drawable et les ai mis dedans, je les ai également ajouté aux autres dossiers drawable juste pour être sûr.

Voici l'erreur

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.whosaidthat.endos.customimagelistview/com.whosaidthat.endos.customimagelistview.MyActivity}: java.lang.NullPointerException: storage == null

Answer 1

Les variables sont nulles lorsque vous les envoyez à l'adaptateur

String[] memeTitles; 
String[] memeDescriptions; 

Je suppose que vous oubliez de le faire:

String[] memeTitles = res.getStringArray(R.array.titles); 
String[] memeDescriptions = res.getStringArray(R.array.descriptions);
