Layout Edtior未显示工具栏-NegativeArraySizeException

在手机和emulator上一切正常,但我无法在Android Studio中使用布局编辑器,因为我遇到以下错误:

无法实例化以下类:

• android支持。v7.widget。工具栏(打开类、显示异常、清除缓存)

我在另一个布局中使用ConstraintLayout时也会得到同样的结果。

想象一下它的样子:

工具栏的我的布局XML:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:theme="?attr/toolbarTheme"
    app:popupTheme="?attr/toolbarPopupTheme"/>

“支持库”的渐变:

// Support Library  
implementation "com.android.support:support-core-utils:${supportLibVersion}"
implementation "com.android.support:appcompat-v7:${supportLibVersion}"
implementation "com.android.support:gridlayout-v7:${supportLibVersion}"
implementation "com.android.support:cardview-v7:${supportLibVersion}"
implementation "com.android.support:design:${supportLibVersion}"
implementation "com.android.support:recyclerview-v7:${supportLibVersion}"
implementation 'com.android.support.constraint:constraint-layout:1.0.2'

supportLibVersion='27.0.2'

我使用Android Studio版本 3.0.1 !

我在其他StackOverflow线程中已经做了哪些工作并发现了哪些问题:
-无效缓存并重新启动
-清理项目和重建项目
-我使用的主题从父级“Theme.AppCompat”更改为“Base.Theme.AppCompat”
