I am trying to achieve below shown effect on page swapping:
my code is:
public class DepthPageTransformer implements ViewPager.PageTransformer {
private static float MIN_SCALE = 1.0f;
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();
if (position < -1) {
// This page is way off-screen to the left.
view.setAlpha(0);
} else if (position <= 0) {
// Use the default slide transition when moving to the left page
view.setAlpha(1);
view.setTranslationX(0);
view.setScaleX(1);
view.setScaleY(1);
} else if (position <= 1) {
// Counteract the default slide transition
view.setTranslationX(-1 * view.getWidth() * position);
// Scale the page down (between MIN_SCALE and 1)
float scaleFactor = MIN_SCALE
+ (1 - MIN_SCALE) * (1 - Math.abs(position));
view.setScaleX(scaleFactor);
view.setScaleY(scaleFactor);
} else {
// This page is way off-screen to the right.
view.setAlpha(0);
}
}
}
Please mention changes which transform to similar as shown in image.
