Bottomsheet Error：该视图不是CoordinatorLayout的子级

Question

我想创建一个布局，其中80％的屏幕包含单独的布局，而20％的屏幕垂直包含底部的页面。但是，当我尝试执行此操作时，出现错误“视图不是CoordinatorLayout的子级”。我得到了错误，但是我想不出其他方法来做到这一点。有人可以帮我实现它吗？帮助将不胜感激。

您能以这种方式尝试吗？

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/bottomSheetLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:behavior_peekHeight="90dp"
    app:layout_behavior="@string/bottom_sheet_behavior">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="230dp"
        android:background="@color/colorPrimary"
        android:orientation="vertical"
        android:padding="@dimen/activity_vertical_margin">
             ...
    </LinearLayout>

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

我所做的就是将以后将要用作其底页的id放在根元素中（顺便说一下，如果需要，可以是ConstraintLayout），您会注意到，该根元素的父元素将自动为CoodinatorLayout。第二件事是将该元素的高度设置为wrap_content布局行为也应该在根元素中。 app:layout_behavior="@string/bottom_sheet_behavior"
