  <version>2.0.0</version>
  <type>pom</type>
</dependency>

❓ Usage

ViewPager

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

ViewPager2

Use these new PageTransformer classes for ViewPager2 instance: BookFlipPageTransformer2 or CardFlipPageTransformer2

💳 Card Flip Example

// Get ViewPager2 and Set Adapter
myViewPager2 = findViewById(R.id.myViewPager2);
pagerAdapter = new MyPagerAdapter(this);
myViewPager2.setAdapter(pagerAdapter);

// Create an object of page transformer
CardFlipPageTransformer2 cardFlipPageTransformer = new CardFlipPageTransformer2();

// 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);

// Assign the page transformer to the ViewPager2.
myViewPager2.setPageTransformer(cardFlipPageTransformer);

📄 Book Flip Example

// Get ViewPager2 and Set Adapter        
myViewPager2 = findViewById(R.id.myViewPager2);
pagerAdapter2 = new MyPagerAdapter(this);
myViewPager2.setAdapter(pagerAdapter);

// Create an object of page transformer
BookFlipPageTransformer2 bookFlipPageTransformer = new BookFlipPageTransformer2();

// 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 ViewPager2.
myViewPager2.setPageTransformer(bookFlipPageTransformer);
