你有没有这样尝试过:

<ScrollView
   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_height="match_parent"
   android:layout_width="match_parent"
   tools:context=".MainActivity"
   app:layout_behavior="@string/appbar_scrolling_view_behavior" >

或者添加 android:layout_below="+@id/toolbar" 或类似 android:layout_below="+@id/appbarlayout"
