android - fragment : Unknown animation name objectanimator

我正在尝试使用以下方法在两个片段之间做一张翻转卡片动画，例如-> Displaying Card Flip Animations:

private void switchFragment(Fragment fragment) {
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction();

        if ((fragment != null) && !(fragment.equals(currentFragment))) {

            if (transactionByMenu) {
                fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
                        android.R.anim.fade_out);
            } else {
                fragmentTransaction.setCustomAnimations(
                        R.animator.card_flip_right_in,
                        R.animator.card_flip_right_out);
            }

            Fragment nextFragment = fragment;
            fragmentTransaction.hide(currentFragment);
            fragmentTransaction.show(nextFragment);

            currentFragment = nextFragment;
        }
        fragmentTransaction.commit();
    }

if(transactionByMenu){...}中的事务有效，但else{...}中不起作用

我会检查自己的库文件和东西，目前的目标位置是api 11，但我仍然收到此错误消息:

我已经坚持了两天，在此先谢谢您。

最佳答案

我相信您正在尝试在支持片段库中使用objectAnimator，但这是在Android Api 11级中添加的。
