Android Question B4XFloatTextField Definitive Guide

[mmieher]

Can someone please point me to the definitive guide to B4XFloatTextField? I have looked at almost every post in the forum, and plowed though all the Guides. The XUI example only does a B4XFloatTextField1.NextField. That's it.

I am trying to create a class that does something like the "..." next to the Text property in Visual Designer. I want to pop up a window where the abuser can enter a bunch of text. Maybe B4XFloatTextField is the wrong thing?

I have a class with a Designer LoadLayout in the DesignerCreateView. It has a Panel with a B4XFloatTextField in it. I cannot seem to get the height of B4XFloatTextField1.TextField to be more than 35dip. I change the height in DesignerCreateView. I log the result which looks good. But when I run the App, the TextField.Height is always 35dip. I want it to be 280dip.

Also, I have set lblClear.top and lblV.top to the same number, but they end up at different y-locs. They must be in different panels. I have tried looping through B4XFloatTextField.TextField.GetAllViewsRecursive but cannot figure out what is going on.

You are trying to interact with B4XFloatTextField internal views. The definite guide for such tasks is the source code (it is inside XUI Views.b4xlib).

Using B4XFloatTextField is very simple. Simply add it with the designer.

Ok. I "simply add it with the Designer".

Must be missing something simple. Attached is a small project. Crash on LoadLayout:
java.lang.RuntimeException: java.lang.ClassCastException: java.lang.String cannot be cast to android.widget.TextView

Main

Sub Process_Globals
End Sub

Sub Globals
    Private mTextTest As mText
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")
    Sleep(0)
End Sub

mText Class

Sub Class_Globals
    Private mEventName As String 'ignore
    Private mCallBack As Object 'ignore
    Private mBase As B4XView 'ignore
    Private xui As XUI 'ignore
    
    Private DebugLevel As Int = 1
    
    Public fxText As B4XFloatTextField
    
End Sub

Public Sub Initialize (Callback As Object, EventName As String)
    LogSub("Initialize: " & EventName)
    mEventName = EventName
    mCallBack = Callback
End Sub

Public Sub DesignerCreateView (Base As Object, Lbl As Label, Props As Map)
    '    Lbl is the entire view from the Designer.  fxWhatever
    LogSub("DesignerCreateView")
    mBase = Base
    mBase.LoadLayout("mTextLayout")
    
End Sub

Public Sub GetBase As Panel
    Return mBase
End Sub

Private Sub fxText_TextChanged (Old As String, New As String)
    LogSub("fxText_TextChanged")
End Sub

Public Sub LogSub(inText As String)
    If DebugLevel = 0 Then Return
    #If DEBUG
    Dim Unit As String = "mText"
    Dim clrLog As Int = 0xFF4DC244
    
    DateTime.TimeFormat = "hh:mm:ss"
    Dim ssTime As String = DateTime.Time(DateTime.Now)
    LogColor(Unit & " " & ssTime & " " & inText,clrLog)
    #End If
End Sub

I "simply add it with the Designer".

Creating a custom view, that only makes things more complicated than they should be, isn't the same as "simply add it with the designer".

Posting part of the error message, without the line number also makes it difficult to help.

You are so right about me making it too hard. Sorry about the error message thing. I did not even notice I left out the important part.
