How to apply a fade-in/fade-out animation when replacing a fragment
提问by Qadeer Hussain
I am replacing a fragment with another fragment. I want the first fragment to disappear with a fade-out effect and second fragment to appear with fade-in effect. How is this done?
我正在用另一个片段替换一个片段。我希望第一个片段以淡出效果消失，第二个片段以淡入效果出现。这是怎么做的？

With addition to @MD code
除了@MD 代码
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction ft = manager.beginTransaction();
ft.setCustomAnimations(R.anim.fade_in,
R.anim.fade_out);
ft.replace(R.id.realtabcontent, fragment);
ft.commit();
and When you Pop Fragment then apply animation like:
当你弹出片段然后应用动画，如：
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction ft = manager.beginTransaction();
ft.setCustomAnimations(R.anim.fade_out, R.anim.fade_in);
ft.replace(R.id.realtabcontent, fragment);
ft.commit();
and XML for fadeIn
和用于淡入的 XML
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="@android:integer/config_mediumAnimTime" />
</set>
and XML for fadeOut
和用于淡出的 XML
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
android:duration="@android:integer/config_mediumAnimTime" />
</set>

It is worth adding that setCustomAnimations can also have 4 arguments:
值得补充的是 setCustomAnimations 也可以有 4 个参数：
FragmentTransaction setCustomAnimations (int enter,
int exit,
int popEnter,
int popExit)
Set specific animation resources to run for the fragments that are entering and exiting in this transaction. The popEnter and popExit animations will be played for enter/exit operations specifically when popping the back stack.
设置特定动画资源以运行此事务中进入和退出的片段。popEnter 和 popExit 动画将在弹出返回堆栈时专门针对进入/退出操作播放。
