Hi for all, i need a bit help with this plz.

Im using this code and works fine, but i need some more.

this code:

            Base = Activity
            Dialog.Initialize (Base)
            SearchTemplate.Initialize
            
            Dim Items As List
            Items.Initialize
            Wait For ( Families(pnl1.Tag, Items) ) Complete (ResultF As Boolean)
            SearchTemplate.SetItems(Items)
            SearchTemplate.Resize(90%x, 90%y)
            
            Dim rs As ResumableSub = Dialog.ShowTemplate(SearchTemplate, "", "", "CANCEL")
            Dim cancelbtn As B4XView = Dialog.GetButton(xui.DialogResponse_Cancel)
            
            cancelbtn.Width = 120dip
            cancelbtn.Left = cancelbtn.Left - 50dip
            
            Wait For ( rs ) Complete (Result As Int)
            If Result = xui.DialogResponse_Positive Then
                log(SearchTemplate.SelectedItem)

In the last line (the log) i get the text of the item clicked.
I need asign a tag in each item and when clicked i need read the tag.

I hope any can help me.
Thanks

The correct solution is to use a Map that maps between the item's text to any other value you need.

Thx Erel for the answer. Just only a few questions.

is possible modify the searchtemplate to add the tag?
if i use Maps is better use something like KeyValueStore?
if i need store 2 lines with the same key but different values, how i need to do that?

Thanks.

No reason to add such tag.

It depends on your requirements. Start with a Map.

Create a custom type and add whichever fields you need.

but the key in the map is not unique? How can I do if I need to repeat the key but with different values. and then get the value of the key clicked

How can the key not be unique? Do you have two items with the same text? How will the user distinguish between the two?

faholet540 · Jul 29, 2020

Yes i can have the same key with different values. I think I'm making it more difficult than it is. I can solve it in another way. With the map you helped me.
Thank you very much Erel.
