AS的设计面板显示不出界面
报错原因是说：在我V7.jar没有Toolbar_buttonGravity这个文件。
解决方法：
修改APP的依赖文件，将不同版本的改成同一版本
例其中一个依赖包是 compile 'com.android.support:appcompat-v7:24.3.0' compile 'com.android.support:recyclerview-v7:23.3.0' compile 'com.android.support:design:25.3.0' 另一个是 compile 'com.android.support:appcompat-v7:25.3.0' 统一改成 25.3.0就好了
