iOS Question Dialogs with B4i and B4A

pliroforikos · Jun 25, 2022

Hello,
I'm trying to convert Β4Α dialog to B4i. But i have some trouble to make them identical.
Below on the left you can see iPhone dialog and right the Android one.

There are 3 float Text Fields in my code and the code is the same

B4A and B4i sub:

Private Sub showDialog
    dlgInsSchool.Initialize(Root)
    dlgInsSchool.Title = textDlgTitle

    dlgInsSchool.TitleBarColor = xui.Color_RGB(83,88,143)
    dlgInsSchool.TitleBarHeight = 50dip
    dlgInsSchool.BorderColor = xui.Color_RGB(83,88,143)
    dlgInsSchool.BorderCornersRadius = 10

    Dim p As B4XView = xui.CreatePanel("")
'    p = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, 350dip, 260dip)
    p.LoadLayout("dlgSchool")
    dlgInsSchool.PutAtTop = True 'put the dialog at the top of the screen
   
    fltSchName.HintText = "School"
    fltSchName.HintColor = xui.Color_RGB(83,88,143)
    fltSchName.Update
   
    fltSchAddress.HintText = "Address"
    fltSchAddress.HintColor = xui.Color_RGB(83,88,143)
    fltSchAddress.Update
   
    fltPostOffice.HintText = "POB"
    fltPostOffice.HintColor = xui.Color_RGB(83,88,143)
    fltPostOffice.Update

    Dim rs As ResumableSub = dlgInsSchool.ShowCustom(p, textBtnOK, textBtnNo, textBtnCancel)
    fltSchName.RequestFocusAndShowKeyboard
'    Dim b As B4XView = dlgInsSchool.GetButton(xui.DialogResponse_Positive)
'    b.Height = 30dip
'    ValidateFields(fltSchName.Text, fltSchAddress.Text, fltSchKey.Text)
    Wait For (rs) Complete (result As Int)

    If result = xui.DialogResponse_Positive Then
        mSchool.Initialize
        mSchool.Put("schname", fltSchName.Text)
        mSchool.Put("url", fltSchAddress.Text)
        mSchool.Put("hash", fltPostOffice.Text)
    End If

End Sub

The worst thing is when i click ok button B4i program crash with this message.

If you want an identical TextField, then I recommend you my AS_TextFieldAdvanced, that looks the same on all 3 platforms, without you having to adjust anything.

[B4X] [XUI] AS TextFieldAdvanced - Title, Information, Counter, Password, Button, Prefix, Suffix, Icons, Multiline

With this view you can quickly and easily add good looking text fields, with title and or bottom text. Additionally you can make the TextField a button, so that you can open menus, but still keep the design of the text fields. The view speeds up development because you don't have to worry about...

Thank you. I did this:

B4X:

Sub Class_Globals
    Private dlg2 As B4XDialog
    Private txt1 As AS_TextFieldAdvanced
    Private txt2 As AS_TextFieldAdvanced
    Private txt3 As AS_TextFieldAdvanced
' And more variables ...

end sub

'Other code...


Private Sub showDialog2
    dlg2.Initialize(Root)
    dlg2.Title = textDlgTitle

    dlg2.TitleBarColor = xui.Color_RGB(83,88,143)
    dlg2.TitleBarHeight = 50dip
    dlg2.BorderColor = xui.Color_RGB(83,88,143)
    dlg2.BorderCornersRadius = 10

    Dim p As B4XView = xui.CreatePanel("")
'    p = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, 350dip, 260dip)
    p.LoadLayout("dlg2")
    dlg2.PutAtTop = True 'put the dialog at the top of the screen
    txt1.Hint.Text = "School"
    txt2.Hint.Text = "Address"
    txt3.Hint.Text = "POB"
    txt1.Refresh
    txt2.Refresh
    txt3.Refresh

    Dim rs As ResumableSub = dlg2.ShowCustom(p, textBtnOK, textBtnNo, textBtnCancel)

    Wait For (rs) Complete (result As Int)

    If result = xui.DialogResponse_Positive Then
        mSchool.Initialize
        mSchool.Put("schname", txt1.Text)
        mSchool.Put("url", txt2.Text)
        mSchool.Put("hash", txt3.Text)
    End If

End Sub

and of course i made the dlg2.bal with designer. But i'm getting the following error when i click on a button to show form:

Thank you Erel. Until now i had B4XPreferencesDialog but i wanted a new "look" for my forms and i couldn't change colors for example Title Bar color or make dialog have rounded corners. Maybe i am wrong

Erel · Jun 26, 2022

You can change these things with B4XPreferencesDialog.

Is there any guide about changing them?

Have you created a nice dialog based on B4XDialog? Post it here. If you have any question then start a new thread.

I found the solution to the crash message.
I made a function to work with KeyboardStateChanged event

B4X:

Private Sub B4XPage_KeyboardStateChanged (Height As Float)
    Log("Page1_KeyboardStateChanged: " & Height)
End Sub
