Citation:

findViewById(R.id.button1).setOnClickListener( new OnClickListener(){

il serait preferable que tu commence d'abord par recuperer ton bouton et ensuite lui appliquer un Listener mais bon on peut dire que ca reste une question de style.

Citation:

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

tu utilise nameValuePairs tu ne lui rajoute jamais de valeur.

Citation:

String strURL="http://127.0.0.1/connexion_mysql/connexion_mysql.php";

si t'es en locale sache que 127.0.0.1 ou localhost ne marche pas.
Utilise l'adresse physique de ta machine .

Citation:

j'ai lu pas mal de discussion sur ce sujet et j'ai un problème classique

si tu lis encore tres bien tu verra que ce problème a été traité comme tu dis

bonjour,
merci pour ta réponse,ça m'a fait avancé, j'ai modifié le "127.0.0.1" par "10.0.2.2" et maintenant j'ai bien vu que je recupere les données mais j'ai tjrs un probleme au niveau du parsing en json:
voici ce qui s'affiche sur le logcat:

Code:

05-28 10:51:41.186: ERROR/log_tag(706): Error parsing data org.json.JSONException: A JSONArray text must start with '[' at character 1 of...

tu peux fait voir ton code !!!
ca sera plus simple si quelqu'un peut t'aider

voici le code PHP:

<?php
// on se connecte à notre base  
$base = mysql_connect ('localhost', 'root', '');  
mysql_select_db ('projetandroid', $base) ;  
 
$req = mysql_query("SELECT *  FROM table1 ;") ;
//or die('Erreur SQL !<br />'.$sql.'<br />'.mysql_error());  
 
// on va scanner tous les tuples un par un  
while ($data = mysql_fetch_array($req)) { 
      // on affiche les résultats 
      echo "Nom : ".$data['nom']; echo '<br />';
      echo 'prenom: '.$data['prix']; echo '<br />';
	  echo '<br /><br />';
}  
mysql_free_result ($req);  
?>

et le parsing json est le suivant:

try{
 
			            JSONArray jArray = new JSONArray(result);
				            for(int i=0;i<jArray.length();i++){
			                @SuppressWarnings("unused")
							JSONObject json_data=jArray.getJSONObject(i);
			                //System.out.println(jArray.getJSONObject(0));
				                // Résultats de la requête
				                returnString += "\n\t" + jArray.getJSONObject(i);
 
				            }
				        }catch(JSONException e){
				            Log.e("log_tag", "Error parsing data " + e.toString());
				        }

c'est quand meme un peu etrange
Nul part tu utilise JSON dans ton code php pour encoder tes données au format JSON

Code:

print(json_encode($output))

par exemple
tu encodes le resultat de ta requete au format JSON apres
tu peux parser ces données dans ton code java

regarde bien les forum precedents tout y est normalement

ah ok je comprend, mais enfait j'avais deja essayé ça (croyant que c'est juste une alternative)mais mon code ne reconnait pas la fonction json_encode:

Code:

1

Call to undefined function: json_encode() in c:\program files\easyphp1-8\www\connexion_mysql\connexion_mysql.php on line 13

voici mon nouveau php:

?>

merci beaucoup pour ton aide karassou, j'ai finallemnt resolu le probleme:
enfait la fonction json_encode n'est pas definie ds la version easyphp 1.8 que j'utilise,elle est ds les versions plus recentes.mais pour l'avoir il siffut de la definir ds le code php comme suit:

    }
