ColinTree list view and data from mysql database

[carto_lover]

i retrieve my datas via a sql query via php script as a list and i put them in a label "lblResult.text"

data is in this format:
urlimg1 - dataa - data b
urlimg2 - dataa2 - data b2
and so on...

i split the data in this way

i want that if there is more than 1 row all of them go in a listview where img.text is the image and the other 2 text are the text to show in listview! As in the example shown on collin tree listview example.

do i have to store them in a tinydb or can i use them on the fly as variables with a foreach ?

something like:

The blocks will not work since you are looping a empty list.

1. Better to change your php file to make it return a CSV table format.
2. Or split the result string with \n into a list , for each item of this list, then split item with '-'

[carto_lover]

this is the content of "lblResult.Text! after the query

i recieve also this error

Argument #2 (com.google.appinventor.components.runtime.ListV...) to 'cn.colintree.aix.ColinTreeListView.ColinTreeListView.Initialize(com.google.appinventor.components.runtime.VerticalArrangement)' has wrong type (com.google.appinventor.components.runtime.ListView) (expected: com.google.appinventor.components.runtime.VerticalArrangement)
Note: You will not see another error reported for 5 seconds.

cannot find how to reproduce this blocks

You only need one of those purple blocks, the ColinTree examples shows both approaches.

[Kevinkun]

the error message have stated it very clear:
the verticalArrangement socket need an VerticalArrangement, not a Listview.

[carto_lover]

it was a vertical arrangment.. i renamed it as listview!

removing second block no errors but listview is not populated

thanks! for sharing that!

the difficult for me is to do with dynamic data and not a static list!
ColinTree_example.aia (1.2 MB)

i want to populate listview searching for example word "panna" in textbox and clicking on x name button!

[dora_paz]

You should get the response from php and split it to 3 lists then use the same approach as in example

Result

Thank you so much! i'll take a look at the blocks and i will ask you if something is not clear because i want to learn!

Also if clicking on x name button i cannot see them:

but i see only the query the first time that i do a search!
after all is fine

[carto_lover]

After the query i recieve an error 1109 the url specified is not valid.
i can see images and text! seems all fine!

can be related to '% %' ?
