片段:未知动画名称 objectanimator [英] Fragment : Unknown animation name objectanimator

问题描述

我正在尝试在两个片段之间进行翻转卡片动画，例如 --> 使用以下方法显示卡片翻转动画:

I'm trying to do a flipping card animation between two fragment like in --> Displaying Card Flip Animations by using:

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){...} 中的事务有效但在 else{...}

我会检查我的库和东西，我目前的目标高于 api 11 但我仍然有这个错误消息:

I'd check my libs and stuff and i'm currently target higher than api 11 but I still have this error message:

我已经被困了两天了，提前谢谢你.

It's been two day I'am stuck with this, thank you in advance.

推荐答案

我相信您正在尝试在支持片段库中使用 objectAnimator，但它是在 Android Api 级别 11 中添加的.

I believe you are trying to use objectAnimator in support fragments library, but it was added in Android Api level 11.
