❓ Usage

Just create an object of either BookFlipPageTransformer or CardFlipPageTransformer and assign it to your ViewPager object by calling ViewPager#setPageTransformer(true, myTransformerObject).

? Card Flip Example

// Get ViewPager and Set Adapter
myViewPager = findViewById(R.id.myViewPager);
pagerAdapter = new MyPagerAdapter(this);
myViewPager.setAdapter(pagerAdapter);

// Create an object of page transformer
CardFlipPageTransformer cardFlipPageTransformer = new CardFlipPageTransformer();

// Enable / Disable scaling while flipping. If false, then card will only flip as in Poker card example. 
// Otherwise card will also scale like in Gallery demo. By default, its true.
cardFlipPageTransformer.setScalable(false);

// Set orientation. Either horizontal or vertical. By default, its vertical.
cardFlipPageTransformer.setFlipOrientation(CardFlipPageTransformer.VERTICAL);

// Assign the page transformer to the ViewPager.
myViewPager.setPageTransformer(true, cardFlipPageTransformer);
Java

? Book Flip Example

// Get ViewPager and Set Adapter        
myViewPager = findViewById(R.id.myViewPager);
pagerAdapter = new MyPagerAdapter(this);
myViewPager.setAdapter(pagerAdapter);

// Create an object of page transformer
BookFlipPageTransformer bookFlipPageTransformer = new BookFlipPageTransformer();

// Enable / Disable scaling while flipping. If true, then next page will scale in (zoom in). By default, its true.
bookFlipPageTransformer.setEnableScale(true);

// The amount of scale the page will zoom. By default, its 5 percent.
bookFlipPageTransformer.setScaleAmountPercent(10f);

// Assign the page transformer to the ViewPager.
myViewPager.setPageTransformer(true, bookFlipPageTransformer);
