它运行良好的应用程序，但在我放置了setContentView（R.layout.activity_main）＆＃39;在我的班级设置内容和显示图像告诉我错误：
android.view.InflateException: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout
我是AndARActivity的继承人，为标记识别做了一个简单的应用程序。
有问题的XML是：
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

我做错了什么？
