Did you try one of these :
您是否尝试过其中之一:
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 :
如果不自行刷新,这应该会提升它:
yourLayout.invalidate();

I'm at work right now, so I can't test this, but I believe this should work:
我现在正在工作,所以我无法测试这个,但我相信这应该有效:
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);
