【Android运行时错误】Error inflating class CollapsingToolbarLayout

近期在调试代码时，突然遇到这样的一个错误，Error inflating class CollapsingToolbarLayout，这里记录一下。

刚开始并不知道问题所在，以为是自己的代码出问题了，因为毕竟报的错误是代码中的

java.lang.RuntimeException: Unable to start activity ComponentInfo

自然而然，我就去查找自己的xml文件，到底有什么错误了

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clickable="true"
            app:contentScrim="@color/blue"
            app:statusBarScrim="@color/blue_dark"
            app:layout_scrollFlags="scroll|exitUntilCollapsed|snap"
            >

         //...省略

        </android.support.design.widget.CollapsingToolbarLayout>

看着xml代码很正常，那么我们还是返回问题本身，错误日志里面是说CollapsingToolbarLayout控件解析异常，那么是否是android.support包导入有问题？
最终，尝试在 gradle文件中，添加v4的支持，运行正常了。

compile ('com.android.support:support-v4:23.4.0'){
    
    
    force = true;
}
