How do you randomly change the relative layout background with a picture?

Question

I am making an app similar to the Fun Facts app but in this one instead of changing the background color i want to change it with a picture.
So I made an array of pictures:
 public int[] mFondo = {
           R.drawable.heart,
           R.drawable.housecane,
           R.drawable.housecaricatura,
           R.drawable.vicodin,
           };
And this is my getBackground method:
 public int getBackground(){
   Random generator = new Random();
int randomNumber = generator.nextInt(mBackground.length);
  return mBackground[randomNumber];
    }
But how do i make this:
relativeLayout.setBackgroundColor(color);
With a picture?

Hello,
I haven't tried this out myself, but a quick search pulled up a question on stackoverflow (http://stackoverflow.com/questions/4906422/setting-background-image-for-relative-layout).  I suggest reading the post, but essentially, you need to do the following:
```java
relativeLayout.setBackgroundResource(getBackground());
```
This is the second suggestion, there are a few others that can work as well.
