how to select from resources randomly (R.drawable.xxxx)

Question

I want to display a random image from the bunch of images i have stored in res/drawable.

The only technique that I know is to access a particular image if you know its r

Answer 1

If you knew you had X images to choose from could use random.nextInt(X) to randomly generate an integer between 0 (inclusive) and X (exclusive), then switch on it to pick your resource:

Random mRand = new Random();
            int x = mRand.nextInt(8);
            switch (x) {
            case 0:
                mResource = R.id.someresource1
            case 1:
                mResource = R.id.someresource2
            ...
            case X:
                mResource = R.id.someresourceX

            }
