Android Question [Solved] Height Challenge with BBCodeview and B4XRadiobutton

omo · Apr 4, 2023

While trying to find a cross platform based radiobutton solution that can be useful in BBcodeview, B4XRadioButton and ASRadioButton came to mind after finding out legacy radiobutton may pose challenge when i finally settle with B4I soon. Three b4xradiobuttons from designer were loaded into panel to work together as group in BBcodeview. It worked as group in bbcodeview, but i found it difficult to adjust height of varying text. I employed different tricks that were not successful like using -2 height wrap with reflection as in legacy radiobutton, but failed to work and not even cross platform compactible with b4J where it complained about missing method. I decided to access individual b4xradiobutton and its label from panel. All i could achieve is this in the picture below which worked only partially in B4J, but did not work at all in B4A. It worked partialy in B4J because all b4xradiobuttons become inactive (not responding to click again).

I also used MeasureTextHeight and MeasureTextWidth, but found it difficult to integrate in BBcodeview environment since all B4XRadiobuttons and label i like to work with are inside panel and if individual B4Xradiobutton is accessed with pnl.Getview(0) or B4xRadioButton1.mBase.GetView(0) or similar, it loses its group attribute and even inactive as shown above.
What i like to achieve with this b4xradiobutton solution is like this image below irrespective of height of text.

Please, i will be happy if i can get a working sample for cross platform solution, below is my experimental code. In this experimental code, i work with B4J and B4A, but i will like it to work in B4I also to avoid too much headache when i finally pitch tent with B4I soon.
Thanks

1. Add each radio button inside a panel. This disables the automatic handling of the buttons.
2.

B4X:

Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private BBCodeView1 As BBCodeView
    Private TextEngine As BCTextEngine
    Private RadioButtonGroups As Map
End Sub

Public Sub Initialize
'    B4XPages.GetManager.LogEvents = True
End Sub

'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    TextEngine.Initialize(Root)
    RadioButtonGroups.Initialize
    BBCodeView1.Text = $"
${CreateRB("aa")} I also used MeasureTextHeight but found it difficult to integrate in BBcodeview environment...

    pnl.SetLayoutAnimated(0, 0, 0, 40dip, 40dip)
    pnl.LoadLayout("RadioButton")
    Dim name As String = ("rb" & BBCodeView1.Views.Size)
    Dim rb As B4XRadioButton = pnl.GetView(0).Tag
    rb.mBase.RemoveViewFromParent
    rb.mBase.SetLayoutAnimated(0, 0, 0, 40dip, 40dip)
    BBCodeView1.Views.Put(name, rb.mBase)
    Return $"[View=${name} Vertical=10/]"$
End Sub

Private Sub B4XRadioButton1_Checked
    For Each v As B4XView In BBCodeView1.Views.Values
        If v.Tag Is B4XRadioButton And v.Tag <> Sender Then
            v.Tag.As(B4XRadioButton).Checked = False
        End If
    Next
End Sub

Not exactly what you want but this is a simple solution that works more naturally with BCTextEngine.
A B4A example is attached.

Whaoo, thank you Erel! This your solution is unique in its nature and has opened my eyes to another programming logic. When combined with other solutions received on other related thread, I can now achieve better solution than what I initially set to acheive. I appreciate.

Hello, sorry i didnt check it well yesterday; only one problem was solved; your solution was not in iteration loop for me to confirm if only one is checked in a group at a time. Is like i don't know how to put your solution in a loop for me to use. When i put it in a for i = 1 to 4 loop, i noticed it wasn't retaining one selection in one group. Below pic is what i got, only one button is being selected among (3 group of 4).

However, what i like to achieve is to retain only one in a group as shown in second pic below. I like that your solution, but i will like if you can give me example code of how i can apply it in group of 3 or 4 radio buttons in 4 or 5 loop. I want one to be selected in a group like below:

Thank you

Thank you Erel, it works on the first run, i have started adjusting for my need. I tested it on android and B4J, it works flawlessly. I am so grateful.
