Android Question button display

[Robert_Poland]

Hello

it needs hints
how to make a button display depending on whether the text edit is something typed
if the button is visible, if not then you can not see the button

thx

Set the button to invisible at designtime

Sub EditText1_TextChanged (Old As String, New As String)
    If New.Trim <> "" Then
        Button1.Visible = True
    Else
        Button1.Visible = False
    End If
   
End Sub

It works great thanks
Now I have to combine
so that the entry in activity 1
caused the activation button on the activity of 2

This will also work:

Sub EditText1_TextChanged (Old As String, New As String)
        Button1.Visible = New.Trim <> "" 
End Sub

and in the activity of two check whether these data as if the button displays
