解决方法:

DanIEl Nugent是对的.你可以这样做：

只需将floatingActionbutton放在该mainlayout上就像这样：

<?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="close">    <androID.support.design.Widget.CoordinatorLayout        androID:ID="@+ID/coordinatorLayout"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"        androID:orIEntation="vertical">        <FrameLayout            androID:ID="@+ID/content_frame"            androID:layout_wIDth="match_parent"            androID:layout_height="match_parent"            app:layout_behavior="@string/appbar_scrolling_vIEw_behavior" />        <androID.support.design.Widget.AppbarLayout            androID:ID="@+ID/appbarLayout"            androID:layout_wIDth="match_parent"            androID:layout_height="wrap_content"            androID:fitsSystemwindows="true">            <include                androID:ID="@+ID/toolbar"                layout="@layout/toolbar" />        </androID.support.design.Widget.AppbarLayout>        <androID.support.design.Widget.floatingActionbutton            androID:ID="@+ID/action_edit"            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_mode_edit_48px"            app:backgroundTint="@color/PrimaryPurple"            app:layout_anchor="@ID/food_queue_recycle_List"            app:layout_anchorGravity="bottom|right|end"            app:layout_behavior="helpers.FABCoordinatorBehavior" />    </androID.support.design.Widget.CoordinatorLayout>    <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:theme="@style/NavigationDrawerStyle"        app:itemIconTint="@color/PrimaryPurple"        app:menu="@menu/activity_dasboard_drawer" /></androID.support.v4.Widget.DrawerLayout>

然后在Fragment中使用RecyclerVIEw：

<relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    xmlns:app="http://schemas.androID.com/apk/res-auto"    xmlns:card_vIEw="http://schemas.androID.com/apk/res-auto"    androID:ID="@+ID/coordinatorLayout"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    app:layout_behavior="@string/appbar_scrolling_vIEw_behavior">    <androID.support.v7.Widget.RecyclerVIEw        androID:ID="@+ID/food_queue_recycle_List"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"        androID:background="@color/Title_white" />    <!-- not sure about this, but, it shouldn't be here -->    <!--<androID.support.v7.Widget.CardVIEw        androID:ID="@+ID/card_vIEw_no_items"        androID:layout_wIDth="350dp"        androID:layout_height="200dp"        androID:layout_centerInParent="true"        androID:visibility="gone"        card_vIEw:cardCornerRadius="2dp"        card_vIEw:cardElevation="4dp">        <relativeLayout            androID:layout_wIDth="match_parent"            androID:layout_height="match_parent"            androID:gravity="center">            <ImageVIEw                androID:ID="@+ID/errorImageVIEw"                androID:layout_wIDth="match_parent"                androID:layout_height="wrap_content"                androID:layout_alignParenttop="true"                androID:layout_centerHorizontal="true"                androID:contentDescription="@string/empty_favourite_List"                androID:src="@drawable/food_icon_empty" />            <TextVIEw                androID:ID="@+ID/errorTextVIEw"                androID:layout_wIDth="match_parent"                androID:layout_height="wrap_content"                androID:layout_below="@+ID/errorImageVIEw"                androID:layout_margintop="@dimen/large_text_size"                androID:gravity="center"                androID:text="@string/empty_favourite_List"                androID:textAllCaps="true"                androID:textcolor="@color/SecondaryBlack"                androID:textSize="@dimen/medium_text_size"                androID:textStyle="bold" />        </relativeLayout>    </androID.support.v7.Widget.CardVIEw>--></relativeLayout>

我不确定那个CardVIEw,因为你将RecyclerVIEw设置为match_parent：

<androID.support.v7.Widget.RecyclerVIEw        androID:ID="@+ID/food_queue_recycle_List"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"        androID:background="@color/Title_white" />

所以,那些卡不应该在那里.(除非你需要将它显示为错误卡)通过将setVisibility设置为GONE,然后处理是否有错误,通过以下方式显示：setVisibility == VIEw.VISIBLE.
