Problème d'affichage d'un contenu MySQL

Bonjour,

Je suis un vrai débutant en Android, je conçois une application me permettant
de gérer mes dépenses.

J'arrive bien à insérer des données d'un formulaire dans ma base mais
c'est l'affichage du contenu de la base dans une listview qui ne marche
pas.

Le fichier à problème s'appelle ListeDepensesActivity.java et il se lance
quand je clique sur le bouton enregistrer du layout main.xml. Le click
sur ce bouton insére les datas dans la base, et j'ai vérifié que les données
insérées sont OK. Après cette insertion, je démarre une intent qui me
lance le fichier ListeDepensesActivity qui est supposé m'afficher une
listeView (layout listedepenses.xml) avec les données de la base.

C'est ce dernier affichage qui me plante. Pouvez vous m'aider svp ?

Merci.

Voici mon main.xml
