/**
* Creates a new 3D rotation on the Y axis. The rotation is defined by its
* start angle and its end angle. Both angles are in degrees. The rotation
* is performed around a center point on the 2D space, definied by a pair
* of X and Y coordinates, called centerX and centerY. When the animation
* starts, a translation on the Z axis (depth) is performed. The length
* of the translation can be specified, as well as whether the translation
* should be reversed in time.
*
* @param fromDegrees the start angle of the 3D rotation
* @param toDegrees the end angle of the 3D rotation
* @param centerX the X center of the 3D rotation
* @param centerY the Y center of the 3D rotation
* @param reverse true if the translation should be reversed, false otherwise

ViewPager 实现 3D 翻转动画 文件
public class ThreeDPageTransformer implements ViewPager.PageTransformer {
private final static String TAG = "FunnyPageTransformer";
private final static float DEFAULT_MAX_ROTATION = 30.0f;
@Override
public void transformPage(View page, float position) {
int pageWidth = page.getWidth();
int pageHeight = page.getHeight();
if (position < -1) { // (-Infinity, -1)
// This page is way off-screen to the left.
page.setRotationY(0.0f);
} else if (position <= 0) { // [-1, 0]
page.setPivotX(pageWidth);
page.setPivotY(pageHeight / 2);
page.setRotationY(DEFAULT_MAX_ROTATION * position);
} else if (position <= 1) { // (0, 1]
page.setPivotX(0);
page.setPivotY(pageHeight / 2);
page.setRotationY(DEFAULT_MAX_ROTATION * position);
} else { // [1, +Infinity)
// This page is way off-screen to the right.

adapter 文件
public class TabFragmentPagerAdapter extends FragmentPagerAdapter {
private FragmentManager mfragmentManager;
private List<Fragment> mlist;

this.mlist = list;
}
@Override
public Fragment getItem(int position) {
return mlist.get(position);
}
@Override
public int getCount() {
return mlist.size();
}
}
添加动画到 viewpager 中
public class Rotate3DTwoActivity extends AppCompatActivity {
private static final String TAG = "Rotate3DTwoActivity";
private ViewPager mViewPager;
// private ViewPagerForScrollerSpeed mViewPager;
private List<Fragment> list;
private TabFragmentPagerAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_rotate3_dtwo);
if (getSupportActionBar() != null){
getSupportActionBar().hide();
}
initVideoData();
mViewPager = (ViewPager)findViewById(R.id.viewPager);
// mViewPager = (ViewPagerForScrollerSpeed)findViewById(R.id.viewPager);
mViewPager.setPageTransformer(true, new ThreeDPageTransformer());
adapter = new TabFragmentPagerAdapter(getSupportFragmentManager(), list);
mViewPager.setAdapter(adapter);
mViewPager.setCurrentItem(0);
mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
private void initVideoData() {
list = new ArrayList<>();
OneFragment oneFragment = new OneFragment();
TwoFragment twoFragment = new TwoFragment();
ThreeFragment threeFragment = new ThreeFragment();
list.add(oneFragment);
list.add(twoFragment);
list.add(threeFragment);
}
@Override
protected void onDestroy() {
super.onDestroy();
}
}
