In B4a questo funziona
B4X: 
    Dim logoBox As ImageView
    logoBox.Initialize("")
    logoBox.Bitmap = LoadBitmap(File.DirAssets, "logo.png")
        #if B4a
    logoBox.Gravity = Gravity.CENTER
     #else if B4i
    ' come lo traduco in b4i (logoBox.Gravity = Gravity.CENTER)
  #End If
    Root.AddView(logoBox, 0, 0, 100%x, 200dip)

In b4i non funziona.
Esiste una versione b4x che va bene per le entrambe versioni?
Grazie mille

Ho fatto queste prove ma vanno in errore

B4X: 
Public logoBox As B4XView
Public ImageView1 As B4XView
logoBox = LoadBitmap(File.DirAssets, "logo.png")
logoBox.SetTextAlignment("CENTER", "CENTER")
Root.AddView(logoBox, 0, 0, 100%x, 200dip)

Dim b As B4XBitmap=xui.LoadBitmapResize(File.DirAssets,"logo.png", 50dip, 50dip, True) 'resizes the image
ImageView1.setbitmap(b)
Root.AddView(ImageView1, 0, 0, 100%x, 200dip)

Il mio scopo è mettere il logo al centro senza essere deformato
in b4a lo provato sia col telefono che col tablet tutto ok
in b4i senza la proprietà il logo si deforma e si allunga
Grazie mille per aiuto

Su Custom view non ho trovato la proprietà per caricare il logo allora ho usato imaview posto il codice

Public Sub Initialize
    B4XPages.GetManager.LogEvents = True
End Sub

'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    AlignImageCenter(logo)
End Sub

'You can see the list of page related events in the B4XPagesManager object. The event name Is B4XPage.

Private Sub Button1_Click
    xui.MsgboxAsync("Hello world!", "B4X")
End Sub


Sub AlignImageCenter(img As ImageView)
    Dim ImageView As ImageView
    ImageView = img.Parent
    If ImageView.IsInitialized Then
        Dim centerX As Int = (ImageView.Width - img.Width) / 2
        Dim centerY As Int = (ImageView.Height - img.Height) / 2
        img.Left = centerX
        img.Top = centerY
    End If

Non capisco perchè non usi le funzioni del Designer, ha tutto quello che ti serve.

Ho il vago sospetto che non ci capiamo.
Secondo me dovresti usare NON ImageView ma B4XImageView, che fa parte della libreria XUI Views, come già detto (e ovviamente anche dichiararla come B4XImageView)

Il tuo rar b4a non va, b4i non ce l'ho, ergo...!

Intanto questo Sub non ti serve.
B4X: 
Sub AlignImageCenter(img As ImageView)
    Dim ImageView As ImageView
    ImageView = img.Parent
    If ImageView.IsInitialized Then
        Dim centerX As Int = (ImageView.Width - img.Width) / 2
        Dim centerY As Int = (ImageView.Height - img.Height) / 2
        img.Left = centerX
        img.Top = centerY
    End If
End Sub

Scrivi nel designer queste 2 rige, e non si deforma niente.
B4X: 
logo.HorizontalCenter = 50%x
logo.Height = 141 * logo.Width / 240

Nota, 141 è l'altezza e 240 è la lungezza impostata da te nel designer.
