Most likely you forgot to add required dependency into your build.gradle script:

implementation 'com.google.android.material:material:1.1.0-alpha10'

You need to add dependencies :

implementation 'androidx.coordinatorlayout:coordinatorlayout:x.x.x'
implementation 'com.google.android.material:material:x.x.x'

Then add the code to your fragment layout xml, like so:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <androidx.appcompat.widget.Toolbar
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="0"
                app:layout_scrollFlags="scroll|enterAlways" />

            <android.support.design.widget.TabLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                app:layout_scrollFlags="scroll|enterAlways" />

        </com.google.android.material.appbar.AppBarLayout>

    </androidx.coordinatorlayout.widget.CoordinatorLayout>

</LinearLayout>

Make sure you have implemented your dependencies and xml correctly. That is it.
