ViewPager.PageTransformer custom animation

CardTransformer.java

/*
  Usage:
  viewPager.setPageTransformer(true, new CardTransformer(0.7f));

public class CardTransformer implements PageTransformer {
 
	private final float scalingStart;

in this code what we can define mBluler and mDimp

@OverRide
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();

if (position < -1) { // [-Infinity,-1)
    // This page is way off-screen to the left.
    view.setAlpha(0);

} else if (position <= 1) { // [-1,1]
      view.findViewById(R.id.ViewPager2);

    mBlur.setTranslationX((float) (-(1 - position) * 0.5 * pageWidth));
    mBlurLabel.setTranslationX((float) (-(1 - position) * 0.5 * pageWidth));

    mDim.setTranslationX((float) (-(1 - position) * pageWidth));
    mDimLabel.setTranslationX((float) (-(1 - position) * pageWidth));

    mCheck.setTranslationX((float) (-(1 - position) * 1.5 * pageWidth));
    mDoneButton.setTranslationX((float) (-(1 - position) * 1.7 * pageWidth)); 
    // The 0.5, 1.5, 1.7 values you see here are what makes the view move in a different speed.
    // The bigger the number, the faster the view will translate.
    // The result float is preceded by a minus because the views travel in the opposite direction of the movement.

    mFirstColor.setTranslationX((position) * (pageWidth / 4));

    mSecondColor.setTranslationX((position) * (pageWidth / 1));

    mTint.setTranslationX((position) * (pageWidth / 2));

    mDesaturate.setTranslationX((position) * (pageWidth / 1));
    // This is another way to do it


} else { // (1,+Infinity]
    // This page is way off-screen to the right.
    view.setAlpha(0);
}
