[Android] ViewPager Animation적용하기

애니메이션 적용

viewpager.setPageTransformer(false, new ViewPager.PageTransformer() {  @Override     public void transformPage(View page, float position) {         // do transformation here         } }); -------------------------------------------------------------------- page Apply the transformation to this page position Position of page relative to the current front-and-center  position of the pager.  0 is front and center. 1 is one full page position to the right, and -1 is one page position to the left.

Now you have a variable that goes from 0 to 1 (and the other way, respectively) if the user scrolls the ViewPager. What you do with it is up to your imagination; here are some basic examples. First, we’ll fade the pages in and out: @Override public void transformPage(View page, float position) {     final float normalizedposition = Math.abs(Math.abs(position) - 1);     page.setAlpha(normalizedposition); } These lines perform a scaling effect from and to 50%: @Override public void transformPage(View page, float position) { final float normalizedposition = Math.abs(Math.abs(position) - 1); page.setScaleX(normalizedposition / 2 + 0.5f); page.setScaleY(normalizedposition / 2 + 0.5f); } The last example rotates the pages around their Z axis by 30 degrees; you don’t need to normalize for this one. The effect is similar to the cover flow UI pattern: @Override public void transformPage(View page, float position) { page.setRotationY(position * -30); }
