  <p><strong>my code is:</strong></p>
  
  <pre><code>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 &lt; -1) { 
  
              // This page is way off-screen to the left.
              view.setAlpha(0);
  
          } else if (position &lt;= 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 &lt;= 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);
          }
      }
  }
