我有一个带有PageTransformer实现的ViewPager,它为ViewPager的下一页做了一些时髦的东西.我的实现看起来像这样:

class ZoomOutPageTransformer implements ViewPager.PageTransformer {
private static final float MIN_SCALE = 0.85f;
private static final float MIN_ALPHA = 0.5f;

@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 <= 0) { // [-1,0]
        // Use the default slide transition when moving to the left page


    } else if (position < 1) { // (0,1]
      do …
