Working sample of fragment inside CoordinatorLayout

gistfile1.xml

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
    </android.support.design.widget.AppBarLayout>

    <fragment
        android:id="@+id/some_fragment"
        android:name="de.no.no.fragments.SomeFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layout="@layout/some_fragment"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        />

</android.support.design.widget.CoordinatorLayout>

Fragment layout behavior not work.

@LuizGadao the fragment must be inside a nestesscrollview... or a framelayout, w/ app:layout_behaviour in it.

Working for me

not working

wrapping in the nestedScrollview helps !!

<androidx.core.widget.NestedScrollView
                            android:layout_width="match_parent"
                            android:layout_height="0dp"
                            android:layout_weight="1"
                        android:fillViewport="true"
                        android:fitsSystemWindows="true"
                        app:layout_behavior="@string/appbar_scrolling_view_behavior">

                           <fragment
                                android:id="@+id/home_fragment"
                                android:name="de.no.no.fragments.SomeFragment"
                                android:layout_width="match_parent"
                                android:layout_height="match_parent"/>

                        </androidx.core.widget.NestedScrollView>
