how to set background in floating windows class?

B4X:

Sub Globals
dim drag1 As ClsFloatingWindow
dim panel1 as panel
end sub

Sub Activity_Create(FirstTime As Boolean)
  Activity.LoadLayout("game3")
   drag1.Initialize(Panel1, 5%x, 40%y, 30%x, 10%y, Me)
   drag1.EnableTitleBar(False)
   drag1.SetBackground(LoadBitmap(File.DirAssets,"g3 soal1 0.png")) ' getting error in here
end sub

As said by the function help text: Background = a valid drawable

B4X:

Dim bmpD As BitmapDrawable
bmpD.Initialize(LoadBitmap...)
drag1.SetBackground(bmpD)

or simpler, with AsPanel:

B4X:

drag1.AsPanel.SetBackgroundImage(LoadBitmap...)

Try so:

B4X:

Sub Activity_Create(FirstTime As Boolean)
  Activity.LoadLayout("game3")
   drag1.Initialize(Panel1, 5%x, 40%y, 30%x, 10%y, Me)
   drag1.EnableTitleBar(False)
   Dim BD As BitmapDrawable = LoadBitmap(File.DirAssets,"g3 soal1 0.png")
   drag1.SetBackground(BD) ' getting error in here
end sub

Without a project to test, it's hard to say.

That should not even compile. For the same reason as the initial post: a bitmap is not a drawable.

Using AsPanel does not seem to work, so use the first solution that I gave. It works.

You are right, it should be:

Dim BD As BitmapDrawable
BD.Initialize(LoadBitmap(File.DirAssets, "MyImage.png"))
