Problème variable globale

mon textview est bien mon layout je crois?

Il doit être dans ton layout si jamais tu l'as rajouté.
Mais de toute façon tu as commenté la ligne setContentView() !!

Tu as maintenant deux solution possibles:
1- supprimer le textView au cas où tu n'as pas un layout (ou bien ce n'est pas important pour toi d'en avoir au moins pour cet exemple)
2- remmettre le setContentView(R.layout.main); au cas où tu as un layout ou bien tu vas faire un. ex:
setContentView(R.layout.main);
textView txtView = (TextView) findViewById(R.id.ResultTextView); // à condition que l'id de ton TextView est bien ResultTextView
task = new TheTask(this, txtView)

de l'autre côté dans TheTaskClass le constructeur sera le suivant:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

   public TheTask(MainActivity a, TextView t){
	activity = a;
        textView = t;
    }

Donc si j'en ai deja un je fais que: remmettre le setContentView(R.layout.main);?

**David55** · 30/05/2014, 16h35

Bonjour tu as un problème à la ligne 34 de ton fichier:

(MainActivity.java:34)

Tu as un soucis d'instanciation. Il te manque un xml (setContentView). Ainsi, tu pourras récupérer ton TextView pour afficher quelque chose dedans.

N'hésites pas à indenter ton code pour qu'on y voit plus clair car comme cela c'est le fouillis.

**mimir02** · 30/05/2014, 16h42

comment connaitre l'id du textview?

**zsalloum** · 30/05/2014, 16h45

Il me semble que tu ne fais pas assez d'effort

le TextView textView = new TextView(this); est faux car tu essaies d'instantier un textView en lui passant une activité qui n'est pas encore construite.
Si tu insistes à avoir un textView mets cette ligne dans onCreate() et fait passer ton textView au task mais cela ne garantit pas que textView.setText dans onPostExecute ne va pas lever une exception car je ne suis pas sûr qu'un simple new TextView(this) sera suffisant (tu dois essayer)

comment connaitre l'id du textview?

si tu l'as créé avec eclipse en utilisant l'éditeur graphique tu peux savoir son id en le sélectionnat et regardant l'id dans les propriétés.
Puis dans ton code tu fais R.id.id_du_textview

**mimir02** · 30/05/2014, 16h50

ok je vais voir

**mimir02** · 30/05/2014, 16h52

il n'as pas d'id, pour le creer c'est bien: android:id="idtextview"?

**mimir02** · 30/05/2014, 16h54

ah non c'est: android:id="@+id/idtextview"

**zsalloum** · 30/05/2014, 16h58

Envoyé par mimir02

ah non c'est: android:id="@+id/idtextview"

donc tu peux utiliser R.id.idtextview le @+id/ sont des flags pour créer l'id au cas où il n'existe pas

**mimir02** · 30/05/2014, 17h00

ok. Par contre, pour mon programme, il faut un listview donc j'ai remplacé les text par list

**mimir02** · 30/05/2014, 17h06

Mais la, il me mets ces erreurs la:
05-30 11:05:47.150: I/taghttppost(1427): java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

ça ne devrait pas être android.R.id.list
mais R.id.list
car il faut utiliser le R qui est généré dans ton projet com.example.basedonnees
tu peux être sûr en allant dans le noued src/gen d'eclipse

c justement le programme qui me dit de le mettre comme ca: regarde les erreurs

while ($row=mysqli_fetch_array($req)) {    
    $output[]=$row;

mysqli_free_result ($req);  
?>

En regardant la doc il semble que dans ton cas le list view id doit être
<ListView android:id="@android:id/list"

**mimir02** · 30/05/2014, 18h24

Super! Ca fonctionne! Merci beaucoup!
