I would like to populate the listview I tried with a csv file in the main directory but it doesn't work.
I also wish I could download it from the site but I don't even know where to start.
Therefore:
from a csv file or other type that are positioned in the root of the mobile, load the data in listview
or download the csv from a site, place them in the main directory, load them in the listview
All the examples I have found either upload data to a webviewer or label or are too difficult for me to understand. amici.csv (11.4 KB)
Your csv file is not valid UTF-8, so it will not work in AI2
You want to save the csv file in the root of the mobile - this is no longer possible, the easiest location is in your application specific directory (ASD) which has a file path:
In the meantime, I apologize, I had forgotten the magic word (Please).
Good question, where is it easier from.
I would need both and I would like to understand how I can turn it into a UTF-8 file
But any example that doesn't take up too much time will do.
It looks like you are generating the file from Excel on Windows.
Open the file with notepad, and save as UTF-8 encoded
(I believe this is correct, don't go near Windows)
Ok I understand I have to get by on my own, I'll search the net, because what you explained to me is Arabic.
Thank you, for the help you have given me so far, you have already been too kind.
I know that you always try to make people learn how to proceed, but I have a hard time remembering, as I have already written (otherwise I would be a billionaire and already an appinventor scientist), but unfortunately every time I create an App I have to go and search the others the blocks, starting them all, even for the simplest operations and sometimes I am forced to run for hours on the net to find blocks of code that I had already created for some time but that I did not remember.
Have a good evening.
Also not understanding English limits me a lot, I often go by intuition.
Have a good evening
Good day, in order not to disturb anyone, I have still been online a lot, because the solution you proposed eliminates all the records in the table instead of just eliminating the brackets.
But I didn't find anything that clarified the problem for me.
Where am I wrong? As you can see I followed your blocks and also modified in the second case, but they don't work
Angelo, hai inserito nel tuo progetto un file excel, non un file di testo, inoltre nel file xlsx tutti i dati iniziano con uno spazio e finiscono con la virgola e questo è sbagliato, correggi e poi salva come csv.
Thank you for the help, but I created the file first from a text file and saved it in csv (UTF-8)
Then the file is loaded normally from the root directory in listview but with the brackets to the right and left of the names)
I also tried to create the file in Google Site as from some examples in Youtube to lro it works but it doesn't work for me and yet I followed their every indication as in these images that I posted.
That file is part of my first experiment, I forgot to delete it.
As I wrote, the file is an actual csv, which I posted to you, but the problem here is not the file, because the file as I wrote is loaded normally, but with brackets in each name, so how do I delete them? I have followed many examples but they do not work with me. What's wrong with the blocks, which ones are the right ones? o HOW I have to modify them.
If you tell me that the error is in the file, do not spare as another create a .csv file.
I deleted that excel file, but again, it was part of my first experiment, to see if it loaded files larger than 5 or 6 names.
I am sending you the threshing floor again
