Give an Id to your LinearLayoutlike this:
给你一个LinearLayout像这样的ID ：
<LinearLayout android:id="@+id/laidout"
...>
and then from your java class say:
然后从你的java类说：
...
case R.id.Button03:
//text.setText("Button 3 was clicked");
.................... // ?
mlayout= findViewById(R.id.laidout);
// set the color
mlayout.setBackgroundColor(Color.WHATEVER);
// you can use setBackgroundResource() and pass appropriate ID
// if you want a drawable bundled as resource in the background
mlayout.setBackgroundResource(R.drawable.background_img);
break;
...

If you want to change the background dynamically, use
如果要动态更改背景，请使用
YourView.setBackgroundColor(Color.argb(255, 255, 255, 255));
