尝试在LinearLayout设置正marginTop并从FAB中删除负值：

<?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:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/floatingActionButtonAdd"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|top"
        android:src="@drawable/ic_add_white_48dp"
        app:backgroundTint="@color/colorPrimary"
        app:borderWidth="0dp"
        app:elevation="4dp"
        app:fabSize="normal"/>

    <LinearLayout

        android:layout_marginTop="32dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:id="@+id/linear_layout_bottom_sheet">

        <!-- include bottom sheet -->
        <include layout="@layout/bottom_sheet_peek" />

        <!-- include main content -->
        <include layout="@layout/bottom_sheet_content" />

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