解决方案

替换你的 xml ->

<android.support.design.widget.AppBarLayoutandroid:id="@+id/appbar"android:layout_width="match_parent"android:layout_height="wrap_content"><android.support.v7.widget.Toolbarandroid:id="@+id/main_activity_toolbar"android:layout_width="match_parent"android:layout_height="?attr/actionBarSize"android:background="?attr/colorPrimary"app:layout_scrollFlags="scroll|enterAlways"></android.support.v7.widget.Toolbar></android.support.design.widget.AppBarLayout><android.support.v4.view.ViewPagerandroid:id="@+id/容器"android:layout_width="match_parent"android:layout_height="match_parent"app:layout_behavior="@string/appbar_scrolling_view_behavior"/><线性布局android:layout_width="match_parent"android:layout_height="match_parent"机器人:方向=垂直"><android.support.design.widget.CoordinatorLayoutandroid:layout_width="match_parent"android:layout_height="0dp"机器人:layout_weight="1"android:id="@+id/placeSnackBar"><android.support.v4.view.ViewPagerandroid:id="@+id/view_pager"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"/><android.support.design.widget.FloatingActionButtonandroid:id="@+id/fab"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="结束|底部"android:layout_margin="@dimen/fab_margin"android:src="@drawable/ic_menu_gallery"/></android.support.design.widget.CoordinatorLayout><android.support.design.widget.TabLayoutandroid:id="@+id/tab_layout"android:layout_width="match_parent"android:layout_height="56dp"android:background="?attr/colorPrimary"/></LinearLayout></android.support.design.widget.CoordinatorLayout>

和 Snackbar 代码将是

Snackbar.make(findViewById(R.id.placeSnackBar), "用你自己的动作替换", Snackbar.LENGTH_LONG).setAction("Action", null).show();

I am facing some problems with new bottom bar.
I can't force to move the snackbar above the bottom bar (this is how design guideline told me should be https://www.google.com/design/spec/components/bottom-navigation.html#bottom-navigation-specs).

This is my activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">

<include
    layout="@layout/app_bar_main_activity"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_main_activity"
    app:menu="@menu/activity_main_drawer" />

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

This is my app_bar_main_activity.xml

<?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="test.tab_activity">

<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/MyAppTheme.NoActionBar.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/main_activity_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/MyAppTheme.NoActionBar.PopupOverlay">

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

</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" />

<LinearLayout 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:orientation="vertical">

    <android.support.v4.view.ViewPager
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_add_white_24dp" />

    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        style="@style/AppTabLayout"
        android:layout_width="match_parent"
        android:layout_height="56dp"
        android:background="?attr/colorPrimary"
        />

</LinearLayout>

The snackbar in main_activity.java looks like this

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(findViewById(R.id.main_content), "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });

解决方案

replace your xml ->

<?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="test.tab_activity">

    <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/main_activity_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways">

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

    </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" />

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

        <android.support.design.widget.CoordinatorLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:id="@+id/placeSnackBar">

            <android.support.v4.view.ViewPager
                android:id="@+id/view_pager"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1" />

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

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

        <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:background="?attr/colorPrimary" />

    </LinearLayout>

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

and The Snackbar code will be

Snackbar.make(findViewById(R.id.placeSnackBar), "Replace with your own action", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show();
