Problème avec l'exemple de contrôle composé?

Question

Je suis en train d'utiliser des contrôles composés, donc j'ai essayé cet exemple dans les domaines suivants link

Mais je reçois un droit FORCECLOSE au début, et la logcat montre beaucoup d'erreurs que je ne comprends pas. J'apprécierais vraiment toute aide.

Voici les erreurs de LogCat

Answer 1

Je pense que les lignes dont vous avez besoin de regarder sont celui-ci:

java.lang.RuntimeException: Impossible de démarrer l'activité ComposantInfo {pete. android.study/pete.android.study.MainActivity}: android.content.res.Resources $ NotFoundException: la ressource n'est pas un Dessins (couleur ou chemin): TypedValue {t = 0x12/d = 0x0 a = 2 r = 0x7f050003}

et celui-ci:

pete.android.study.MainActivity.onCreate (MainActivity.java:20)

regard à la ligne 20 de votre MainActivity. Vous essayez de définir quelque chose à un drawable qui n'est pas compatible.
