Java 如何将片段插入到布局xml文件中？

我有一个Android布局文件和一个片段类。如何将片段添加到布局文件中

Android布局文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="346dp"
    android:layout_height="match_parent"
    android:background="@drawable/botonera_registradora_bg"
    android:gravity="center_horizontal">
...
==> here I need to put my fragment
...
</RelativeLayout>

XML中的FrameLayout。然后，您必须以编程方式在活动中添加片段

该活动将与您的RelativeLayout关联，片段将有自己的布局

这样,

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="346dp"
 android:layout_height="match_parent"
 android:background="@drawable/botonera_registradora_bg"
 android:gravity="center_horizontal">

  <FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/frameLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="346dp"
 android:layout_height="match_parent"
 android:background="@drawable/botonera_registradora_bg"
 android:gravity="center_horizontal">

  <FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/frameLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

</RelativeLayout>

     ItemDetailFragment itemDetailFragment=new ItemDetailFragment();

      FragmentTransaction transaction = 
  getFragmentManager().beginTransaction();

transaction.setCustomAnimations(animSlideIn, animSlideOut, animSlideIn, animSlideOut);
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN).replace(R.id.frameLayout, itemDetailFragment)
        .commitAllowingStateLoss();`
