AlertDialog personnalisée

Bonjour,

Est-il possible de changer la taille du texte sur le NegativeButton d'un alertDialog ?

Je pense que ça ferait l'affaire :

Code:

1
2
3
4
5
6
7
8
9
10
11
final AlertDialog alert = builder.create();
alert.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        Button btnPositive = alert.getButton(Dialog.BUTTON_POSITIVE);
        btnPositive.setTextSize(TEXT_SIZE);
 
        Button btnNegative = alert.getButton(Dialog.BUTTON_NEGATIVE);
        btnNegative.setTextSize(TEXT_SIZE);
    }
});

j'ai déjà essayé ce code :

Code:

1
2
3
4
5
6
 
 AlertDialog dialog = alert.create();
            System.out.println("ok1");
            // Positive 
        dialog.getButton(DialogInterface.BUTTON_POSITIVE).setTextSize(TypedValue.COMPLEX_UNIT_PX, (float) 8);
            System.out.println("ok2");

et le log m'indique null pointer exception,

voici un extrait du log

merci pour votre aide

Peut-être parce que le bouton n'existe pas encore quand tu essayes de modifier la taille de son texte. D'où le code de Neolex avec le OnShowListener :mrgreen:
