How do they do this? animated drawer rotation possible?

In the screenshots below, touching the ‘Touch’ circle at the bottom causes that circle to rotate around itself, and then 4 new navigation buttons come out that take me to other screens/activities in the app. I really want to have this in my app..

Is it a sliding drawer or some other strategy? BTW I am targeting android version 2.1

    It looks as if it’s mainly a animation that rotates an image. Once the animation has finished, the buttons are activated.

    ImageView discsAndButtons = (ImageView) findViewById(R.id.discsAndButtons);

Animation anim = new RotateAnimation(0.0f, 90.0f, 0.0f, 480.0f);
anim.setDuration(600);
anim.setFillAfter(true);
anim.setAnimationListener(this);

discsAndButtons.setAnimation(anim);

...

void onAnimationEnd(Animation animation) {
   ViewGroup buttonLayer = (ViewGroup) findViewById(R.id.buttonLayer);
   buttonLayer.setVisibility(View.VISIBLE);
}

    Visually, the buttons are part of the image. But the effective buttons are probably on a separate layer above the image and only made visible after the animation has finished (except for the TOUCH button).
