Android 如何在父片段中添加子片段？

我有主布局。我想在主线布局中添加片段。但若我想在主片段中添加子片段，它当前是存在的并且是可见的

<LinearLayout
    android:id="@+id/linearlayout_fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/footer"
    android:layout_below="@id/header"
    android:orientation="vertical" >
</LinearLayout>

现在我想在当前主片段中添加子片段：

FragmentManager fragmentManager = getChildFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

RepairFragment repairFragment = RepairFragment.newInstance();
repairFragment.setRetainInstance(true);
fragmentTransaction.add(R.id.linearlayout_fragment, repairFragment);
fragmentTransaction.commit();

但我有个例外：

我试过：

fragmentTransaction.replace(getParentFragment().getId(), repairFragment);
fragmentTransaction.replace(getView().getId(), repairFragment);

因此，请尝试另一种xml

       <FrameLayout
            android:id="@+id/linearlayout_fragment"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_above="@+id/footer"
            android:layout_below="@id/header" >

        </FrameLayout>

已解决。刚刚为父片段布局分配了id

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearlayout_repair_fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textview_repair"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="repair" />

    <TextView
        android:id="@+id/textview_repair_1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="repair 1 " />

</LinearLayout>

那个么你们想把碎片分成碎片，变成碎片活动吗？不，碎片中的碎片在碎片活动中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearlayout_repair_fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textview_repair"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="repair" />

    <TextView
        android:id="@+id/textview_repair_1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="repair 1 " />

</LinearLayout>

fragmentTransaction.replace(R.id.linearlayout_repair_fragment, repairFragment);
