Android 支持库中的FloatingActionButton导致异常。为什么？

我有以下布局活动_fab.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:elevation="20dp"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <android.support.design.widget.CoordinatorLayout
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >


        <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|right"
        android:layout_marginBottom="10dp"
        android:layout_marginRight="10dp"
        android:src="@drawable/ic_info_outline_white_36dp" />

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

</LinearLayout>

这是一个非常简单的例子。但是，它仍然会因logcat的以下输出而崩溃：

我不能，因为类型不可见。这是否意味着我的suuport库版本（23.0.1）的访问修饰符有问题？ 为什么会发生这种错误？如何修复

编辑： 在大众的需求，我也张贴我的风格和主题

这个@RestrictTo（GROUP_ID）注释是否可能限制类的可见性？

于是出现了一个子问题？如何找到特定版本的支持库的源代码？

你能发布你的应用级别

build.gradle

？我没有使用gradle。还是日食。安卓工作室是一种慢用的方式。那个么你们可能就不走运了。谷歌在2015年发布了Eclipse。不管怎样，我最初的想法是，如果您还没有包括设计支持库，那么您可能还需要基本支持库。是什么让您留在Eclipse上，您是否厌倦了成为Eclipse工程师，Eclipse有问题，请将my man更新到安卓studio，否则我们可能会在来世找到你LOL@Lutaaya我们之所以继续使用这个版本的支持库，有一些原因，就eclipse而言，android studi的ozr测试非常不令人满意。慢，一些缺少的功能，慢，它使用了很多ram，所以很难打开所有其他需要的东西，我是不是说android studio非常慢。你能发布你的应用程序级别
