片段动画无法正常使用 support-v4:27.1.0

getSupportFragmentManager()
       .beginTransaction()
       .setCustomAnimations(ENTER_ANIM , LEAVE_ANIM)
       .replace(R.id.main_activity_fragment_place_holder, fragment)
       .addToBackStack(tag)
       .commitAllowingStateLoss();

进入动画

<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="500" />

离开动画

<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0"
android:duration="500" />
