Android Question Resize panel does not resize bitmap

[tsteward]

I am using SimpleMediaManager to load an image onto a panel that is declared as a b4xview.

When I resize the panel the image does not resize with it. I need it to.

Assign the image

Private Sub ShowMedia (Result As MediaChooserResult)
    If Result.Success Then
        smm.SetMediaFromFile(PanelBase, Result.MediaDir, Result.MediaFile, Result.Mime, Null)
    Else
        'Panel1.RemoveAllViews
    End If
End Sub

Resize like this

Private Sub btnZoomOutHor_Click
    PanelBase.SetLayoutAnimated(0,PanelBase.Left,PanelBase.Top,PanelBase.Width - zoomFactor,PanelBase.Height)
End Sub

Private Sub btnZoomInHor_Click
    PanelBase.SetLayoutAnimated(0,PanelBase.Left,PanelBase.Top,PanelBase.Width + zoomFactor,PanelBase.Height)
End Sub

Private Sub btnZoomOutVert_Click
    PanelBase.SetLayoutAnimated(0,PanelBase.Left,PanelBase.Top,PanelBase.Width,PanelBase.Height - zoomFactor)
End Sub

Private Sub btnZoomInVert_Click
    PanelBase.SetLayoutAnimated(0,PanelBase.Left,PanelBase.Top,PanelBase.Width,PanelBase.Height + zoomFactor)
End Sub

Maybe I don't understand you completely, but in the main properties you can turn automatic resizing on or off. So if you don't resize the main, but only a panel, then that is not a resize of the main. You will have to do that yourself in that case.

where do you see this in B4A?

My solution was to put a B4XImageView onto the panel and resize that with the panel

You have now linked the B4XImageView (the child) to the panel (the parent) which, according to the Common properties, recalculates the dimensions based on the vertical and horizontal Anchors. You can deviate from this (or even confuse it) by using a script in the Common Properties. Sometimes it also helps to force the screen display to refresh with a sleep(0) command.
