Something like this:

B4X:

Panel1.Color = Colors.ARGB(50, 128, 45, 50)

You can create a transparent panel with an ImageView. You will then be able to change the ImageView image.

Create a transparent panel and add an ImageView over it.

You can draw a semitransparent color over a bitmap and then call rv.SetImage to update the ImageView.

This works fine here:

pnlBlack is used to dimm effect over Main Panel...

B4X:

    pnlBlack1.Initialize("pnlBlack1")
    pnlBlack1.Color=Colors.ARGB(0,0,0,0)
    'Activity.AddView(pnlBlack1,0,Panel1.Top+Panel1.height+1dip,100%x,100%y-Panel1.Top+Panel1.height)
    pnlMain.AddView(pnlBlack1,0,Panel1.Top+Panel1.height+1dip,100%x,100%y-Panel1.Top+Panel1.height)
    pnlBlack1.BringToFront

B4X:

Sub fadeTimer_Tick()


 
    If fd>dimValue Then
        fd=dimValue
        pnlBlack1.Color=Colors.ARGB(fd,0,0,0)
        fadeTimer.Enabled=False
        'pnlBlack2.Color=Colors.ARGB(fd,0,0,0)
        fd=0
    Else
 
        fd=fd+2
        If fd>dimValue Then fd=dimValue
        pnlBlack1.Color=Colors.ARGB(fd,0,0,0)
        'pnlBlack2.Color=Colors.ARGB(fd,0,0,0)

    End If


End sub

FORGET THIS - I didn't see that you asked for a widget (remote view)!

The question is about a home screen widget, not regular activity.
