Hello Alls,
In project, I try to a imageview and a label on a button. code like this
B4X:
    Button1...properties set
    Button1.SendToBack

    ImageView1...properties set
    ImageView1.BringToFront

    Label1...properties set
    Label1.BringToFront
test on android 4.X ,it display ok.
but on android 8.0 (huawei), it does not display img and label text.
So why button BringToFront and SendToBack no effect ?

and thanks

I test using a label replay button like. And project on android 8.0 (huawei),
img and text display ok.

B4X:
Button1...properties set
    Button1.SendToBack

'use label replace button
    Button1.Visible =False
    Dim lbl As Label
    lbl.Initialize("lbl")
    Activity.AddView(lbl,Button1.Left,Button1.Top,Button1.Width,Button1.Height)
    Dim cd2 As ColorDrawable
    cd2.Initialize2(Colors.DarkGray,8dip,2dip,Colors.White)
    lbl.Background = cd2
    lbl.SendToBack

    ImageView1...properties set
    ImageView1.BringToFront

    Label1...properties set
    Label1.BringToFront
