我试图动画片段之间的过渡.我从以下Android片段和动画中得到了答案

FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);

DetailsFragment newFragment = DetailsFragment.newInstance();

ft.replace(R.id.details_fragment_container, newFragment, "detailFragment");

// Start the animated transition.
ft.commit();

还有我的R.anim.slide_in_left

<?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>

但当我尝试这个时,它表明了

我想通过动画在一个活动中交换两个片段.假设PageA用于屏幕A和左侧屏幕,PageB用于片段B,即屏幕右侧.现在我希望当我点击pageA上的一个按钮时,PageA将移动到屏幕的右侧,带有一些过渡动画.

我尝试了以下代码来替换位置

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.container, new FragB());
fragmentTransaction.commit();

寻找一些线索.

提前致谢.

我正在使用支持包v4的Google API 8(Android 2.2).

它不会给出任何错误或动画.

交易:

FragmentTransaction transaction = manager.beginTransaction();       
transaction.replace(R.id.content, myFragment);
transaction.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
transaction.commit();

动画:

slide_in_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="700"
        android:fromXDelta="-100%"
        android:toXDelta="0%" >
    </translate>
</set>

slide_out_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="700"
        android:fromXDelta="0%"
        android:toXDelta="100%" >
    </translate>
</set>

有谁知道这里发生了什么？
