Code Description:
1. Here we use the built-in switching effects @ android: anim/slide_in_left and @ android: anim/slide_out_right.
2. Prepare your own test images.
Java
Bottom = (ViewSwitcher) findViewById (R. id. bottom );
// Switch to the first
Bottom. setDisplayedChild (0 );
// Switch to the next
// Bottom. showNext ()
