Did you try one of these :
yourLayout.setBackgroundColor(int color);
yourLayout.setBackgroundDrawable(Drawable d);
yourLayout.setBackgroundResource(int resid);
and if does not refresh on its own, this should give it a boost :
yourLayout.invalidate();

I'm at work right now, so I can't test this, but I believe this should work:
LinearLayout linLay = (LinearLayout) findViewById(R.id.theLinearLayoutId);
//set background to a color
linLay.setBackgroundColor(Color.parseColor("#404040"));
//set background to a drawable
linLay.setBackgroundDrawable(drawableItem);
//set background to a resource
linLay.setBackgroundResource(R.id.backgroundResource);

Bizon, from your comment, are you just trying to change to a different layout when the phone is switched to landscape mode versus portrait mode? If so, you should make a new layout.xml file, and place it under res/layout-land/ developer.android.com/guide/topics/resources/index.html

setBackgroundColor(...) is a integer method. You cannot pass a string a string argument to it.

setBackgroundColor(Color.parseColor("")); would work, just put the color string inside the parseColor method

@user413881, I hit the "Up Arrow" just now because I tried and it neither worked for me but, I looked my code again, and found that works, the issue was I have a customized ChipLayout (extends LinearLayout), and I only changed the background resource on the reference of the ChipLayout, but forgot to change the background resource of the ChipLayout itself, change to operate on the ChipLayout everything works. Hope this could be helpful to other.
