按网上的说法，要使用CoordinatorLayout，应该直接在build.gradle中添加依赖 compile 'com.android.support:design:26.1.0' 便可：
可是添加后在布局文件中引用时，却出现无法预览的问题：
后来百度了一下，说是要修改主题为AppTheme中的其中一种，但是默认不就是AppTheme吗，好吧，改：
改完之后还是不行，预览没问题了，但是编译会闪退报错，即报了开头日志的错误，又搜了半天，发现要在AndroidManifest.xml中进行修改才行，直接将主题替换为：android:theme="@style/Theme.AppCompat.Light.NoActionBar"，然后build一下项目或者重启就可以了。要用design包下的东西，基本上都要改这个。
