Archivo csv cargar y ver con un boton

[David_Huanca_Sanga]

Estimados, buen día.

Quisiera saber si alguien me puede ayudar con lo siguiente:

Estoy desarrollando una app en MIT App Inventor y deseo implementar una funcionalidad en la que, al presionar un botón, se cargue un ListView con los ítems que ya tengo almacenados en un archivo .csv (el cual ya tengo preparado y cargado en el proyecto).

La idea es que, una vez se muestre esa lista, el usuario pueda seleccionar uno de los ítems y que, al hacerlo, se abra otra pantalla (Screen2) donde se muestre el contenido detallado de ese ítem (por ejemplo, una descripción asociada).

Agradecería mucho si alguien pudiera orientarme con los bloques necesarios o un ejemplo similar.
¡Desde ya muchas gracias!

at the press of a button, it loads a ListView with items that I already have stored in a file .csv

use the file component to read the file from the assets
then in the GotText event convert the csv file into a list by using the split block, just split at \n to get each row of the csv file in a separate lisst item and assign that list to the listview elements property

The idea is that, once you display the list, the user can select one of the items, and that, by doing so, you open another screen (Screen2) showing the detailed content of that item (for example, an associated description).

use the same screen to display the details, if necessary use virtual screens, see also tip 1 here

This list was made by @Taifun Use different screens wisely Before starting to create another screen, first you should think about is it really necessary? See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... If you decided to use different screens, then you should switch them correctly, else you …
