Add custom layout to ActionBar/Toolbar with no margins

Question

I want to create a custom height toolbar and it works fine until I add content to it. Then my content is adjusted to be between the back arrow and the actionbar buttons.

I'm not sure if you still need help with this, but it has the most votes for an unanswered question in not only the android-5.0-lollipop tag, but also the android-toolbar tag right now. So, I thought I'd give it one.

This layout is pretty easy to achieve, especially with the new Design Support Library.

Implementation

The root of your hierarchy will need to be the CoordinatorLayout.

As per the docs:

Children of a CoordinatorLayout may have an anchor. This view id must correspond to an arbitrary descendant of the CoordinatorLayout, but it may not be the anchored child itself or a descendant of the anchored child. This can be used to place floating views relative to other arbitrary content panes.

So, we'll use this to position the FloatingActionButton where it needs to go.

The rest is pretty straightforward. We're going to use a vertical LinearLayout to position the Toolbar, text container, tab container, and then a ViewPager. So, the full layout looks like:

<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#181E80"
        android:orientation="vertical">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:minHeight="?attr/actionBarSize" />

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="48dp"
            android:paddingTop="8dp">

            <ImageView
                android:id="@android:id/icon"
                android:layout_width="54dp"
                android:layout_height="54dp"
                android:layout_alignParentStart="true"
                android:layout_marginStart="16dp"
                android:importantForAccessibility="no"
                android:src="@drawable/logo" />

            <TextView
                android:id="@android:id/text1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignTop="@android:id/icon"
                android:layout_marginStart="14dp"
                android:layout_toEndOf="@android:id/icon"
                android:text="Chelsea"
                android:textColor="@android:color/white"
                android:textSize="24sp" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignStart="@android:id/text1"
                android:layout_below="@android:id/text1"
                android:text="England - Premier League"
                android:textColor="@android:color/white"
                android:textSize="12sp" />

        </RelativeLayout>

        <FrameLayout
            android:id="@+id/tab_container"
            android:layout_width="match_parent"
            android:layout_height="90dp"
            android:background="#272F93">

            <android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"
                app:tabContentStart="70dp"
                app:tabGravity="center"
                app:tabIndicatorColor="#F1514A"
                app:tabMode="scrollable"
                app:tabSelectedTextColor="@android:color/white"
                app:tabTextColor="#99ffffff" />

        </FrameLayout>

        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </LinearLayout>

    <android.support.design.widget.FloatingActionButton
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_margin="16dp"
        android:src="@drawable/ic_star_white_24dp"
        app:backgroundTint="#F1514A"
        app:borderWidth="0dp"
        app:elevation="8dp"
        app:layout_anchor="@id/tab_container"
        app:layout_anchorGravity="top|right|end" />

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

There's not a whole lot more to add, the only other thing I'd mention is how to use the TabLayout. If you're using a ViewPager like we are, you'd probably call one of the two:

• TabLayout.setTabsFromPagerAdapter
• TabLayout.setupWithViewPager

Notes

I just kind of eyeballed the dimensions, trying to match the picture as much as possible.
