Bug? Bug? Or Strange Attractors?

[William Lancee]

As is common in this forum, bugs are often caused by lack of full understanding of the underlying processes. This may be one of those. Nevertheless, I found it interesting and challenging to solve.

In my app, an editText appears to magically change shape, based on a strange attraction to the activity of another editText.

My first thought when seeing your code: You should never reuse the same drawable with multiple/different views. Add a third Option to the thread title: "Coding error/mistake".

untested:

Sub CreateCD() As ColorDrawable
    Dim cd As ColorDrawable
    cd.Initialize2(Colors.RGB(240, 240 ,255), 3dip, 1dip, Colors.Black)
    Return cd
End Sub
Sub Activity_Create(FirstTime As Boolean)
    Activity.Color = Colors.RGB(245,245,245)


    editBox.Initialize("editBox")
    editBox.TextSize = 20
    editBox.TextColor = Colors.Black
    editBox.Gravity = Gravity.TOP
    editBox.Visible = False
    editBox.Background = CreateCD
    editBox.InputType = Bit.Or(editBox.InputType, 524288)        'to remove autosuggest
    Activity.addView(editBox, 10%x, 33%y, 80%x, 25%y)
 
    inputBox.Initialize("inputBox")
    inputBox.TextSize = 20
    inputBox.TextColor = Colors.Black
    inputBox.Visible = False
    inputBox.Background = CreateCD
    inputBox.InputType = Bit.Or(inputBox.InputType, 524288)        'to remove autosuggest
    Activity.addView(inputBox, 50%x, 10%y, 20%x, 5%y)

    Dim alphnum As String = "abcdefghijklmnopqrstuvwxyz"
    alphnum = alphnum & alphnum.toUppercase & "0123456789,_"
    kbInput.Initialize("kbInput")
    kbInput.SetCustomFilter(inputBox, inputBox.INPUT_TYPE_TEXT, alphnum)
    kbInput.AddHandleActionEvent(inputBox)

    kbEdit.Initialize("kbEdit")
    kbEdit.SetCustomFilter(editBox, editBox.INPUT_TYPE_TEXT, alphnum)
    kbEdit.AddHandleActionEvent(editBox)

    CallSubDelayed(Me, "showProblem")         'callSubDelayed to let the kb handlers get ready
End Sub

Thanks Don, that's what I concluded. However I didn't know why that would be the case. Since the post I found a lucid article about this phenomena. The problem is easily avoided.
