Please tell me how to hide the OK button when opening a custom dialog with an input field. After entering characters, the OK button should appear.

Here you go

In the Sub Show(title As String,message As String,Ok As String,Cancel As String,No As String, icon As Bitmap) As ResumableSub
Add this line right after the line "Dialog.ShowCustom":

B4X:

    rs = Dialog.ShowCustom(x, Ok, No, Cancel)
    EditName_TextChanged("", "")

And here is the Sub EditName_TextChanged:

B4X:

Sub EditName_TextChanged (Old As String, New As String)
    Dim bt As B4XView = Dialog.GetButton(xui.DialogResponse_Positive)
    bt.Visible = (New.Length > 0)
End Sub
