Probably the easiest way is a ViewFlipper w/left & right transition
animations:
1) extend a ViewFlipper
2) make 4 TranslateAnimations (inFromLeft, outToLeft, inFromRight,
outToRight, adjust the constructors as necessary)...
private final TranslateAnimation mInFromLeft =
new TranslateAnimation(Animation.RELATIVE_TO_PARENT,-1.0f,
Animation.RELATIVE_TO_PARENT,0.0f,
Animation.RELATIVE_TO_PARENT,0.0f,
Animation.RELATIVE_TO_PARENT,0.0f
);
3) add a GestureDetector to catch flings. In the OnGestureListener
method, set the appropriate animations for the ViewFlipper's
setInAnimation() and setOutAnimation() methods, then call the
ViewFlipper's showPrevious()/showNext() methods based on the direction
of the fling (or movement)
4) if you want "book-ends" like the home screen, check for the
displayed child index before you call showPrevious()/showNext() in the
OnGestureListener method body. Otherwise, you can just blindly call
showPrevious()/showNext() for a "carousel" effect, the ViewFlipper
will automatically "wrap" back to the first index when it reaches the
end.
Or, dig into the "Home" source which is included w/the SDK (platforms
\android-1.5\samples\Home\src\com\example\android\home)
