Android - How to make fragment transition animation with toolbar using getChildFragmentManager

Question

I try to implement a navigator object. It has own stack.

My activity layout hierarchy is below:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<FrameLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

My fragment hierarchy is here:

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/fragmentRootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:elevation="4dp"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@color/colorPrimary" />

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbar"
    android:id="@+id/fragmentContentLayout">
</FrameLayout>

To replace fragmentA and fragmentB with animation, toolbar is animated when I use getSupportFragmentManager of activity.

But this is not fit for my requirement. Because I want each navigator to has a different stack. So, I use below code with animation(right to left)

getChildFragmentManager().beginTransaction().replace(R.id.fragmentRootLayout, fragment);

But toolbar doesn't slide right to left.
