Encore un message d'erreur

Bonjour

Quand j'ai ce message sur le LogCat

Code:

12-20 16:52:45.493: ERROR/AndroidRuntime(31857): at com.wtp.applimultipage.page_1_1.onCreate(page_1_1.java:29)

Est-que cela veut dire que j'ai une erreur sur la ligne 29 de page_1_1.java ?
Cela se produit quand je clic sur le menu Page_1_1

L'émulateur refuse l'affichage

Ma ligne 29 est

Code:

mNomText = (EditText) findViewById(R.id.nom);

Et j'ai aucune erreur sur le code
J'avoue ne rien comprendre
Pouvez-vous me guider SVP

Citation:

Est-que cela veut dire que j'ai une erreur sur la ligne 29 de page_1_1.java ?

Oui

Assure toi que le ContentView est bien chargé avant cette opération , ainsi que l'identifiant R.id.nom appartient bien à ce layout que tu as chargé .

Prends ton temps relis bien ton code.

PS : Ce n'est pas parce qu'il n'y a pas d'erreur détectée par la pré-compilation, que pour cela le code est fonctionnel . La pré-compilation regarde juste la syntaxe de tes déclarations et non pas le côté fonctionnel de ton code .

Bonjour et merci de me répondre

C'est ce code ?

Code:

protected void onCreate(Bundle savedInstanceState) {
    	super.onCreate(savedInstanceState);
    	mDbHelper = new DBAdapter(this);
        mDbHelper.open();
        setContentView(R.layout.page_1_1);

l'id nom est sur cette page page_1_1

JCM

Le ContentView a l'air bien chargé .

Maintenant je ne peux pas voir ton code en entier .

Pour débugger tes erreurs tu dois t'aider des outils à ta disposition , cad ,
->le logcat avec les remontées d'erreur , d'exception de la SDK d'android .
-> le logcat avec la remonté de tes log , ce qui te permettra de suivre l'avancement de tes variables ainsi que le l'avancement de ton application (interaction entre thread , passage d'activity ,...)
-> le dernier est le mode debug qui te permet de pouvoir prendre ton temps pour suivre le fonctionnement et trouver l'erreur , je te conseille de poser un breakpoint et de suivre "pas à pas" ton code suite à cela.
-> il y en a d'autre mais pour l'instant cela suffise.

Sur cet exemple , pose ton breakpoint à l'entrée de la fonction onCreate et suis pas à pas ton code , prends le temps de bien voir si les variables se mettent à jour et si les valeurs trouvées sont cohérentes avec celle attendues .

Bonjour

Je n'arrive pas à trouver l'erreur
Je suis reparti de 0 en m'inspirant du tuto Notepad3

En fait ce qui me bloque l'affichage (refus de l'émulateur), c'est quand je rajoute un champs dans la table

J'ai pourtant ajouté le code dans le .string et dans les .java et nouveau champs est bien dans le R.java

voici le LogCast

Voilà tu as toutes les billes pour corriger ton erreur

Désolé d'avoir déposé cette requete à vos service

J'ai fini par trouver l'erreur, il s'agissait d'un changement de nom d'un button

Merci pour votre aide
