Android Question [Solved] where is focus after activity-create? Set that view per code?

Which view has the focus after activity-create?
Can I set this focus per code?

(background: I want to remove focus from edittext after Enter pressed. The Reflector solution removes the ability to get focus, not acceptable. Did not test phone hidekeyboard , as the code is in a class. To use an Edittext outside the screen is a lousy solution imho. Try to set focus to the parent panel also fails. Isn't there a neat/fair solution?)

On the first focusable one. First in your layout (see the "Views Tree").

EditText1.RequestFocus

Set the Panel as "focusable".

B4X:

Sub Activity_Create
    Activity.Loadlayout("xxx")
    SetFocusable(Panel1, True)
    EditText1.RequestFocus
' '''
End Sub

B4X:

Sub EditText1_EnterPressed
    RequestFocus(Panel1)
End Sub

Sub SetFocusable(Vw As View, Focusable As Boolean)
    Dim jo As JavaObject = Vw
    jo.RunMethod("setFocusable", Array(Focusable))
    jo.RunMethod("setFocusableInTouchMode", Array(Focusable))
End Sub

Sub RequestFocus(Vw As View)
    Dim jo As JavaObject = Vw
    jo.RunMethod("requestFocus", Null)
End Sub

Thank you, Lucas, that is nearly perfect!

1. is seems that

B4X:

Sub EditText1_EnterPressed
    Panel1.RequestFocus
End Sub

also works. Is that correct?

2. The focus is lost. Fine! But the keyboard is still opened. Can I force it to close as well?

If it works, that's correct ?

I didn't remember (I didn't think) that Panels could receive the focus that way.

Use IME Library to hide the keyboard
