TexBox dei ricordi

MIT App Inventor Help
1

Salve,
ho creato una piccola app per la spesa; e tramite l’immissione in una Texbox del prodotto, vado a incrementare una ListView, che a sua volta, salva il tutto tramite una TinyDB. Come è possibile permettere alla TexBox di poter ricordare tutti i prodotti, inserirti precedentemente?
Grazie
Nicola
P.s: Volevo allegare un file AIA, ma il sistema mi dice che sono un nuovo utente; e per questo non posso farlo :unamused:

Hello,
I created a small shopping app; and by entering the product in a Texbox, I am going to increase a ListView, which in turn saves everything via a TinyDB. How is it possible to allow TexBox to remember all the products, insert yourself previously?
Thank you
Nicola
P.s: I wanted to attach an AIA file, but the system tells me that I am a new user; and for this I cannot do it: unamused:

You could try using Taifun’s textbox extension to word search the tinydb

Ciao Tim,
ho appena completato la mia app della spesa, ma la cosa strana è che provandola con il Companion, funziona; ma dopo aver creato l’APK, mi visualizza degli errori.
Ti allego il file AIA
Auguri di Buon San Stefano
Nicola

Hi Tim,
I have just completed my shopping app, but the strange thing is that trying it with the Companion, it works; but after creating the APK, it displays errors.
I am attaching the AIA file
Greetings from Buon San Stefano

which error you you get?
probably a permission issue?

If you are asking for help, I recommend you to make it as easy for others to be able to help you ...

You probably will get more feedback then...

which means in your case post a screenshot of your relevant blocks...

To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...

Thank you.

Would generate errors in companion for me!

You are setting your global variable “ConteggioProdotti” as a list, when it is a value/number
Change “create empty list” to 0 in your Screen1.initialise and your variable declaration then it should work

Actually, it would be better to use the length of list Oggetto for your number, then it would always be synchromised.

Ciao Tim
ho cambiato “crea un elenco vuoto” su 0 sia in Screen1.inizialize e sia nella dichiarazione della variabile “ConteggioProdotti”; ma l’errore rimane.

Hi Tim
I changed “create an empty list” to 0 both in Screen1.inizialize and in the declaration of the variable “ConteggioProdotti”; but the error remains.

Salve Taifun,
adesso le allego le immagini degli errori.
Il 1 errore viene visualizzato nel momento in cui tenta di caricare una gif animata; mentre il 2 errore, dopo la sua chiusura.
Nicola

Hi Taifun,
now I attach the images of the errors.
The 1 error is displayed when attempting to load an animated gif; while the 2nd mistake, after its closure.

Did you remember to set development to false before compiling ?

(Google Translate: Ti sei ricordato di impostare lo sviluppo su false prima della compilazione?)

15

Hai ragione, difatti mi ero dimenticato di impostare lo sviluppo su False, prima della compilazione. :neutral_face:
Ringrazio sia te che Taifun per il vostro aiuto prezioso.
Saluti
Nicola

You’re right, in fact I forgot to set the development to False, before compilation. : Neutral_face:
I thank you and Taifun for your valuable help.
