Android Question AS Settings SelectionList

[Sergio Haurat]

Hi @Alexander Stolte, I am trying to implement "SelectionList". I downloaded the example file in #1 and couldn't find a code segment that explains the correct way to do it.

The example code seen above:
- What would be the way to call .ShowPage?
- Is there a way to change the text size of the elements to make them smaller? (I have some records with text that does not look good, so large and with so many characters)

I have managed to run using .ShowPage in .Action, but when selecting an item, it returns the following error.

** Activity (main) Resume **
Error occurred on line: 1604 (AS_SettingsPage)
java.lang.RuntimeException: Object should first be initialized (View).
Did you forget to call Activity.LoadLayout?

Graphic example to show you the problem with text size

What would be the way to call .ShowPage?

In the main example project of the AS_Settings, there is an example with a 2nd page, search for SettingPage2 in the ide to find it.

Is there a way to change the text size of the elements to make them smaller? (I have some records with text that does not look good, so large and with so many characters)

No there is not yet, the text size is still hardcoded for the SelectionList

have managed to run using .ShowPage in .Action, but when selecting an item, it returns the following error.

Please provide an example project, what shows the error. I can't help you with just an error message.

 

[Sergio Haurat]

I attach an example with part of the code.

Another wish that I have is to be able to pass to the ComboBox a Map variable instead of List, by this way, I can obtain a code for each record, when I capture the value of the ID as happens with "_ValueChanged(Property As AS_Settings_Property, Value As Object)".

Otherwise, I have to send only the descriptive text of the record and when the selection event is executed, go through the Map variable by its description to know the code.

VB.Net example

Dim strSQL As String
Dim adm_lst_docs As New DataTable
strSQL = "select"
strSQL &= " adm_lst_docs._id as adm_lst_docs_id,"
strSQL &= " adm_lst_docs._desc" & strMyLang & " as adm_lst_docs_desc"
strSQL &= " from adm_lst_docs"
strSQL &= " order by"
strSQL &= " adm_lst_docs_desc"
MySQLCmdInterSys.CommandText = strSQL
MySQLDAInterSys.SelectCommand = MySQLCmdInterSys
MySQLDAInterSys.Fill(adm_lst_docs)
Me.cmbTypeDoc.DataSource = adm_lst_docs
Me.cmbTypeDoc.DisplayMember = "adm_lst_docs_desc"
Me.cmbTypeDoc.ValueMember = "adm_lst_docs_id"

but when selecting an item, it returns the following error.

Fixed in V2.04

Dear @Alexander Stolte, I'm still having problems with the code. Would you be so kind as to use the example I sent you with the correct coding

 

[Alexander Stolte]

I'm still having problems with the code

And how am I supposed to know what these problems are? I have tried the example and when I select something there is no more error.

I'm sorry, but I don't feel like programming right now, I'll be expanding the library over the next few days/weeks.

The problem remains the same. In the original post I attached an example that generates the error. I understand that you can test it from there.

Sorry if this is annoying, but in the library example there is no example of "AddProperty_SelectionList", only a link to part of the code without any explanation of how to integrate it into the rest of the project.

Again. I have downloaded the last b4xlib on the lib. thread, open your example project from #3 and there is no error if i select something on the list in B4A.

Sorry if this is annoying, but in the library example there is no example of "AddProperty_SelectionList", only a link to part of the code without any explanation of how to integrate it into the rest of the project.

You're right about that.

New Example Project:

[B4X] AS Settings - SelectionList Property

https://www.b4x.com/android/forum/threads/b4x-xui-as-settings.147435/ With this property, you can offer the user several options and he can then select either one or more. Example 'Second Page SettingPage2.Initialize(AS_Settings1,"Page #2")...

Thank you so much. Have a great weekend.

I think this is a bug, if you select the same element (an already selected element), the value is null instead of the value assigned to that element.
