android.view.InflateException: Binary XML file line #2: Error inflating class android.support.constraint.RelativeLayout

您有一个布局资源，其中有一个名为android.support.constraint.RelativeLayout的XML元素。 Android中没有这样的类。 RelativeLayout可以在您的布局中简称为RelativeLayout。

您可以发布开发应用程序的API吗？ 你做过任何更新？检查你的SDK包，

或者

使用一个线性布局或相对布局创建一个activity2.xml，并通过删除u setContentView中的旧activity1.xml来申请活动，然后运行应用程序..

试试这个
