TabLayout inside Toolbar

问题

I want to achieve a certain look with the new Design Support Library and I can't stop seeing a weird bug.

Here's the screencast with the desired output (not done with DSL) And the ouput I get using DSL.

The toolbar+tabs is in an activity with a viewpager, and the recyclerView is inside a fragment within the viewpager (the adapter actually, but you get my point)

Code for the activity :

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:fab="http://schemas.android.com/apk/res-auto"
    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.support.v7.widget.Toolbar
            android:id="@+id/toolbar_main"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:elevation="4dp"
            app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_scrollFlags="scroll|enterAlways">

            <android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:tabIndicatorColor="@color/white"
                app:tabTextColor="@color/selected_text"
                app:tabSelectedTextColor="@color/white"/>

        </android.support.v7.widget.Toolbar>

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

    <android.support.v4.view.ViewPager
        android:id="@+id/main_pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

    <android.support.design.widget.SupportFloatingActionsMenu
           ...>
           /* Code for a fancy fab w/ menu */

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

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

For the fragment containing the recyclerView :

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.insa.burnd.view.MainActivity.NewsfeedFragment"
    android:id="@+id/fragment_newsfeed">

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipe_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </android.support.v4.widget.SwipeRefreshLayout>

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

The java code is pretty standard, I bing the viewpager to the tabs... etc.

Thank you in advance for your help :) !

This and many other bug fixes were fixed in version 22.2.1 of the Design Library. Please make sure your build.gradle file references the newest version.
