 错误信息如上：view与BottomSheetBehavior不匹配？？？

这是什么鬼呢？？？

由于BottomSheetBehavior填充的view需要为 android.support.design.widget.CoordinatorLayout 的一个子view，这时候，比如view在布局中为一个相对布局，需要这样写：

 <RelativeLayout
        android:id="@+id/layout_bottom_sheet"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        android:background="@android:color/white"
        android:elevation="8dp"
        app:behavior_hideable="true"
        app:behavior_peekHeight="90dp"
        app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

        <TextView
            android:id="@+id/text_view_sheet_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="@dimen/activity_vertical_margin"
            android:text="点击叫车,上滑选车"
            android:textSize="14sp" />

    </RelativeLayout>

 注意红色声明，这时候用BottomSheetBehavior填充这个view的时候才是正确的.
