Generate Random Numbers and Set a Random Resource as Background for a View in Android?

This code generates a random integer using Android's Random class, and sets a randomly selected drawable as background for a View.

Place your images into /res/drawable/ and update private int pics[] with the drawables from which you want to pick one randomly

private int pics[]=  {R.drawable.p1, R.drawable.p2, R.drawable.p3, R.drawable.p4, R.drawable.p5};

private Random rand = new Random();

public int set_rand_pic() {

    int pos = rand.nextInt(pics.length-1);

    mycard.setBackgroundResource(pics[pos]);

    return pos; 

}
