Android错误膨胀FloatingActionButton

Question

我开发和Android应用程序，一切都很完美，然后我有一个简单的代码，测试和无错误，然后当我尝试测试应用程序时，我的主屏幕活动开始抛出以下3个错误：

Caused by: android.view.InflateException: Binary XML file line #53: Error inflating class android.support.design.widget.FloatingActionButton

Caused by: java.lang.reflect.InvocationTargetException

Caused by: java.lang.IllegalAccessError: tried to access class android.support.v7.widget.AppCompatImageHelper from class android.support.design.widget.FloatingActionButton

ActivityMainScreen.java setContentView(R.layout.activity_main_screen);中的所有三个错误同时存在于同一行（onCreate()）中，问题是我所拥有的代码是一种不同的活动，甚至与主要的相关，所以我不知道它可能是什么，希望你能提供帮助，这是错误的代码：
