我认为在使用以下代码使用片段时按下后退按钮时系统会在后台堆栈上反转动画：

FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.setCustomAnimations(R.anim.slide_in, R.anim.hyperspace_out);
ft.replace(R.id.viewContainer, new class(), "layout").addToBackStack(null).commit();

根据自定义动画的android文档：

改变：

ft.setCustomAnimations(R.anim.slide_in, R.anim.hyperspace_out);

到：

ft.setCustomAnimations(R.anim.slide_in, R.anim.hyperspace_out, R.anim.hyperspace_in, R.anim.slide_out );

现在后台动画 - 反向！

使用正确的动画我使用了以下动画，它的工作就像一个魅力

slide_in_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_mediumAnimTime" >
    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="1000"
        android:valueTo="0"
        android:valueType="floatType" />
</set>

slide_in_right.xml

 <?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_mediumAnimTime" >

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="0"
        android:valueTo="1000"
        android:valueType="floatType" />

</set>

slide_out_left.xml

   <set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_mediumAnimTime" >

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="0"
        android:valueTo="-1000"
        android:valueType="floatType" />

</set>

slide_out_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_mediumAnimTime" >

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="-1000"
        android:valueTo="0"
        android:valueType="floatType" />

</set>

然后在添加片段时使用以下

setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_left,
                                R.anim.slide_out_right, R.anim.slide_in_right)

它会 100% 工作

就我而言

fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right, 
                       R.anim.slide_in_right, R.anim.slide_out_left);

将创造完美的动画。

slide_in_right

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="50%p" android:toXDelta="0"
               android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
           android:duration="@android:integer/config_mediumAnimTime" />
</set>

slide_out_left

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="0" android:toXDelta="-50%p"
               android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
           android:duration="@android:integer/config_mediumAnimTime" />
</set>

.setCustomAnimations(R.animator.fragment_fade_in,
        R.animator.fragment_fade_out,
        R.animator.fragment_fade_p_in,
        R.animator.fragment_fade_p_out)

将以上内容替换为：

mFragmentManager.beginTransaction()
    .setCustomAnimations(R.animator.fragment_fade_in,
            R.animator.fragment_fade_out,
            R.animator.fragment_fade_p_in,
            R.animator.fragment_fade_p_out)
    .replace(R.id.main_container, FragmentPlayerInfo.getInstance(data))
    .addToBackStack(FragmentPlayerInfo.TAG)
    .commit();

正如 Fragment Transaction 类中提到的那样。

/**
     * Set specific animation resources to run for the fragments that are
     * entering and exiting in this transaction. The <code>popEnter</code>
     * and <code>popExit</code> animations will be played for enter/exit
     * operations specifically when popping the back stack.
     *
     * @param enter An animation or animator resource ID used for the enter animation on the
     *              view of the fragment being added or attached.
     * @param exit An animation or animator resource ID used for the exit animation on the
     *             view of the fragment being removed or detached.
     * @param popEnter An animation or animator resource ID used for the enter animation on the
     *                 view of the fragment being readded or reattached caused by
     *                 {@link FragmentManager#popBackStack()} or similar methods.
     * @param popExit An animation or animator resource ID used for the enter animation on the
     *                view of the fragment being removed or detached caused by
     *                {@link FragmentManager#popBackStack()} or similar methods.
     */
    @NonNull
    public abstract FragmentTransaction setCustomAnimations(@AnimatorRes @AnimRes int enter,
            @AnimatorRes @AnimRes int exit, @AnimatorRes @AnimRes int popEnter,
            @AnimatorRes @AnimRes int popExit);

所以最后你可以使用这样的方法

 mFragmentManager.beginTransaction()
                        .replace(R.id.container, fragment)
                        .setCustomAnimations(R.anim.slide_left,//enter
                                             R.anim.slide_out_left,//exit
                                             R.anim.slide_right,//popEnter
                                             R.anim.slide_out_right)//popExit
                        .addToBackStack(fragment.toString())
                        .commit();

这对我有用！这段代码片段！如果要在活动中使用此代码，请在开头删除getActivity()！

getActivity().getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.fade_out,android.R.anim.slide_in_left, android.R.anim.fade_out)
        .replace(R.id.fragment_container, new YourFragment)
        .addToBackStack(null)
        .commit();

祝你好运！！
