It is a combination of layout gravity and anchor gravity together with playing with the margins (of the anchored item) that can make it work, have a look at the xml below which I have used successfully:

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_dialog_info" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="top|end"
    android:layout_marginBottom="0dp"
    android:layout_marginEnd="0dp"
    android:layout_marginLeft="0dp"
    android:layout_marginRight="0dp"
    android:layout_marginStart="0dp"
    android:layout_marginTop="0dp"
    android:src="@android:drawable/ic_media_play"
    app:layout_anchor="@id/fab"
    app:layout_anchorGravity="top" />

Solution 2

Try to use this app:useCompatPadding="true"

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fabBottom"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:tint="@android:color/white"
    android:src="@mipmap/ic_search"
    app:fabSize="normal"
    android:scaleType="center"
    app:layout_anchor="@+id/bottomSheet"
    app:layout_anchorGravity="top|end"
    app:useCompatPadding="true"/>

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fabTop"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:tint="@color/accent"
    android:src="@mipmap/ic_location_on"
    app:backgroundTint="@android:color/white"
    app:fabSize="normal"
    android:scaleType="center"
    android:layout_gravity="top|end"
    app:layout_anchor="@+id/fabSearch"
    app:layout_anchorGravity="top|end"
    android:layout_margin="12dp"/>

Here is my solution, just put an invisible fab between the two fabs, and works well with CoordinatorLayout.

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:src="@drawable/ic_check" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_invisible"
    android:layout_width="@dimen/fab_margin"
    android:layout_height="@dimen/fab_margin"
    android:layout_gravity="top|end"
    android:layout_margin="@dimen/fab_margin"
    android:visibility="invisible"
    app:layout_anchor="@id/fab"
    app:layout_anchorGravity="top" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_follow"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="top|end"
    android:layout_margin="@dimen/fab_margin"
    android:src="@drawable/ic_gps_fixed_follow"
    app:backgroundTint="@android:color/white"
    app:layout_anchor="@id/fab_invisible"
    app:layout_anchorGravity="top" />

I can't believe no one has posted the correct answer.

Wrap the buttons in a ViewGroup and apply the dodgeInsetEdges layout parameter so that the buttons move up with the bottom sheet. For the above use case, we can use a LinearLayout with the XML attribute app:layout_dodgeInsetEdges="bottom".

Note that we can apply this to any view in a CoordinatorLayout.

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

    <!-- We can use any ViewGroup here. LinearLayout is the
         obvious choice for the questioner's use case. -->
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:orientation="vertical"
        app:layout_dodgeInsetEdges="bottom">

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/upperFab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="@dimen/fab_margin"
            android:src="@drawable/upper_fab_icon" />

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/lowerFab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/lower_fab_icon" />

    </LinearLayout>

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

Solution 5

This works for me - FABs are embedded in Relative layout:

<?xml version="1.0" encoding="utf-8"?>
<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:fitsSystemWindows="true"
    tools:context="com.github.openeet.openeet.SaleDetailActivity">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/appbar_padding_top"
        android:theme="@style/AppTheme.AppBarOverlay">

        <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/AppTheme.PopupOverlay">

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

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

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

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

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_margin="@dimen/fab_margin"
        android:layout_gravity="end|bottom" >


        <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab_share"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="end|bottom"
            android:src="@android:drawable/ic_menu_share"
            android:layout_alignParentBottom="true"
            android:layout_alignLeft="@+id/fab_print"
            android:layout_alignStart="@+id/fab_print" />

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab_print"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="end|bottom"
            android:src="@android:drawable/ic_media_next"
            android:layout_above="@+id/fab_share"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginBottom="46dp" />

    </RelativeLayout>

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

The material design documentation has an example of Google Maps showing two floating action buttons next to one another (actually, one above the other).

enter image description here

How is this done? I have two FAB's in a coordinator layout, but they end up on top of one another, so you only see one button.

<?xml version="1.0" encoding="utf-8"?>
<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">

    <!-- Use ThemeOverlay to make the toolbar and tablayout text
             white -->
    <android.support.design.widget.AppBarLayout
        android:id="@+id/abl_top"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:fitsSystemWindows="true"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
    </android.support.design.widget.AppBarLayout>

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

        <ImageView
            android:id="@+id/img_photo"
            android:layout_width="match_parent"
            android:layout_height="256dp"
            android:background="#C5C5C5"/>
        <EditText
            android:id="@+id/text_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/img_baby"
            android:layout_alignParentStart="true"

            android:drawablePadding="20dp"
            android:textAppearance="?android:attr/textAppearanceSmall" />
        <TextView
            android:id="@+id/text_dob"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/text_name"
            android:layout_alignParentStart="true"
            android:layout_alignParentLeft="true"
            android:hint="Date of birth"
            android:drawableLeft="@drawable/ic_cake"
            android:drawablePadding="20dp"
            style="@android:style/Widget.Holo.Spinner"/>

    </LinearLayout>
