UserBO:

}
public long getB(){
	return B;
}
public void setB(long B) {
	this.B = B;
}
String A;
String B;

}

et le code qui utilise tout

Main.java:

ArrayList<UserBO> listUsers1 = getUsers(2);
	UserBO user1 = listUsers1.get(0);
	id = Integer.parseInt(user1.getId());
	A = Long.parseLong(user1.getA());
	B = Long.parseLong(user1.getB());

[....]

public ArrayList<UserBO> getUsers(int id){    	    	

DBAdapter dbAdapter=DBAdapter.getDBAdapterInstance(this);
try {
	dbAdapter.createDataBase();
} catch (IOException e) {
	Log.i("*** select ",e.getMessage());
}
dbAdapter.openDataBase();		
String query="SELECT * FROM user where id = "+id+";";
ArrayList<ArrayList<String>> stringList = dbAdapter.selectRecordsFromDBList(query, null);
dbAdapter.close();

ArrayList<UserBO> usersList = new ArrayList<UserBO>();
for(int i=0; i<stringList.size(); i++){
	ArrayList<String> list = stringList.get(i);
	UserBO user = new UserBO();
	user.id = Integer.parseInt( list.get(0) );
	user.A = Long.parseLong( list.get(1) );
	user.B = Long.parseLong( list.get(2) );

	usersList.add(user);
}
return usersList;
}

donc voila comment faire pour changer de ligne ? je change id avant array list(ca ne change pas les donner A et B)? ou je refait une array list.? si quelqu'un a le courage je met mon code en chantier a disposition si on me le demande par mail... mais attention au yeux... ici c'est plus clair

[chpil]

je change id avant array list(ca ne change pas les donner A et B )?

Je dirais 'oui' (si je comprends bien la question...)

[TecKnologikS]

justement ca change pas les donnée... il semble rester sur le meme id de ligne

[chpil]

En es-tu sûr ? Tu as les bonnes données ? ou pas ?

[TecKnologikS]

non ce ne sont pas les bonnes... mais je vais essayer soit de stocker tout dans différentes variables soit sans passer par une variable faire directement un if Long.parseLong(user1.getA()) = 0 ... enfin je vais m'arranger... je posterai la réponse si ca marche !

[TecKnologikS]

resultat : une mauvaise gestion des get user... en revoyant j'ai trouver les erreur.. donc ce que tu m'a dit etait bon.. la gestion de la base etait bonne c'etait la gestion des fonctions qui faisait tout raté !

Merci
