image1Fetch valeur EditText dans la boîte de dialogue, ajout également requis pour les utilisateurs valeurs saisies
Salut, j'essaie d'obtenir boîte de dialogue en cliquant sur le bouton « Ajouter » ....
Avant cela, je voudrais vous donner une petite explication de ce que je dois accomplir. Ici, j'ai des éléments listView. La liste comprend le nom des éléments et editText. L'utilisateur peut entrer des valeurs dans cet editText. Supposons qu'un utilisateur saisisse trois valeurs d'éléments dans le texte d'édition (par exemple: Tomoto 30, Soup 40, Biriyani 50). En outre, il y a un bouton "ADD" qui affiche une fenêtre contextuelle avec une boîte de dialogue sur le même écran lorsque vous cliquez. À l'intérieur de la boîte de dialogue, il doit être montré le nom de l'article et la valeur entrée par l'utilisateur, ces totaux également nécessaires dans le cas de l'exemple ci-dessus (Tomoto 30, Soup 40, Biriyani 50..Total 120). Si quelqu'un peut aider, il sera facile de transmettre et de réaliser ma demande .... Merci à l'avance
