Is it possible to set all scrollview innerpanel elements with the same backgound image.

Then put some other images (which have transparent backgounds but have some drawings) on this backgrounds...

B4X: 
    For i = 0 To Bitmaps.Size - 1
        Dim iv As ImageView 'create an ImageView for each bitmap
        iv.Initialize("")
        Dim bd As BitmapDrawable
        bd.Initialize(Bitmaps.Get(i))
        iv.Background = bd 'set the background of the imageView.
        scrl_allNotes.Panel.AddView(iv, 30, 120  + i * 60, 480, 40)
    Next

as it is seen in the code above we are already using background property to set images in every row... Then how can I we overlap two images (one of them transparent mostly)?

You can put a second ImageView or a Panel on top of the previous Imageviews.

Thank you klaus,
But at that time i had to initialize same images many times.
My list is already containing more than 50 images.
And more 50 for backgrounds. At total = more than 100 images. I dont want app to become so source hungry.

Is there any way of using same imageview as an element of scrollview many times ?

B4X: 
        '###Header Of ScrollView
        Dim h_iv As ImageView 
        h_iv.Initialize("") 
        Dim h_bd As BitmapDrawable
        h_bd.Initialize(LoadBitmap(File.DirAssets, "allnotesheader.png"))
        h_iv.Background = h_bd 
        scrl_allNotes.Panel.AddView(h_iv, 0, 0, 480, 120)
    
    For i = 0 To Bitmaps.Size - 1 '###size of bitmap is more than 50
    
        '###Repeating Elements That Will Be Used As Backgrounds
        Dim s_iv As ImageView 
        s_iv.Initialize("") 
        Dim s_bd As BitmapDrawable
        s_bd.Initialize(LoadBitmap(File.DirAssets, "notelistsatir.png"))
        s_iv.Background = s_bd 
    
        '###Rows Of Bitmap Files That Will Be Used As Foreground Layer
        Dim iv As ImageView
        iv.Initialize("")
        Dim bd As BitmapDrawable
        bd.Initialize(Bitmaps.Get(i))
        iv.Background = bd 
        scrl_allNotes.Panel.AddView(s_iv, 0, 120  + i * 40, 480, 40) '###Background Layer
        scrl_allNotes.Panel.AddView(iv, 30, 120  + i * 40, 480, 40)  '###Foreground Layer
    Next
