if i wanna show from the listview which is relating to the customer only as the tag has texts including name and number so i wanna get the customer elements from his name
You can debug this by adding a new global variable Taglist_debug.
When FirebaseDB1.TagList
set global Taglist_debug to value
(rest of your blocks, working off the new global variable for Do It debugging.)
do you mean like that or what should i do to fix?
How can we help you if we don't know what arrives in value after the TagList is done?
Think of a way to show the value contents.
let me show you
in that firebase data there will be many filled data by customers and i arranged them by the tag so the tag is having the customer name,city and number so in the cart when the customer is showing his orders requests he should see only from the listview what did he filled, so i wanna the list view showing what the tag having his name only!
This is the list filter block.

This ListView and Dictionary , Keys are very confusing in MIT app. Don't know, why they made it so complicated.
Everyone has the same problem with ListView Block.
You should've learnt the basics of App Inventor before telling that, and remember that you will find the same concepts on languages like Python, C#, etc.
I think you are right. But I am saying there is no standard List and Dictionary block diagram coding. As we change the JSON format, the blocks get also changed. There are many JSON format and for every JSON format the listview , Dictionary blocks get changed.
Can you personally help me? I got stucked somewhere in LISTVIEW block in my project. Can you guide me Remotely by taking my system remote access ? I would be very greatful to you.
You need to show your example json, your blocks for conversion and listview, someone here will help.
I do not provide private support.
No.
unfortenatelly, didn't work yet,
here is my new firebase tag hoping to help me in it
the new tag is having a number and a phone number inside the tag,
all i want is to retreive what is related the same number from all firebase data from the tag
Here is an article by Firebase with recommendations for structuring your Firebase data:
https://firebase.google.com/docs/database/ios/structure-data
just send me aia file and i will make my data fit to it to implement my request please
The word 'number' by itself is inadequate to describe the context of the number.
- trip number for the driver that day?
- driver license number?
- customer account number?
- ... ?
ok show me a tag example and block for getting an split retrieve from the tag, if the tag has two values for example i wanna retrieve with one value only
Your tags can't be split because they don't have special characters like '|' between the parts of the tag.
The special character must be something that won't appear inside any data item in the tag.
Otherwise, the list indexes of the items in the split list will be off.
