ok, I got it, I see this:

B4X:

    Dim b As Button
    b.Initialize("")
    Activity.AddView(b, 0, 0, 200dip, 200dip)
    Dim jo As JavaObject = b
    Dim e As Object = jo.CreateEvent("android.view.View.OnTouchListener", "btouch", False)
    jo.RunMethod("setOnTouchListener", Array As Object(e))

Click to expand...

Private b as Button

b.Initialize("btn")
Activity.AddView(b, 0, 0, 200dip, 200dip)

Private Sub btn_Click
    Log("Button was clicked.")
End Sub
