What you are looking for is ViewPager.PageTransformer
.
With a PageTransformer
, you can zoom the View as it is being swiped into view.
Here's an example of one that will zoom the way you want. Try this to start:
public static class PageTransformer implements ViewPager.PageTransformer {
@Override
public void transformPage(View page, float position) {
// this part changes the scale, which is the zoom part
page.setScaleX(1.0F - .33F * Math.abs(position));
page.setScaleY(1.0F - .33F * Math.abs(position));
// this part sets up so the page zooms from the center
page.setPivotX(page.getWidth() / 2.0F);
page.setPivotY(page.getHeight() / 2.0F);
}
}
To set it up:
viewPager.setPageTransformer(false, new PageTransformer());
