Question

我正在使用这个库'com.mahc.custombottomsheetbehavior:googlemaps-like:0.9.1'来创建BottomSheet，除了layout_behavior之外，每件事都没问题，当我添加它时，会出现渲染问题

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/ma_bottom_sheet"
    android:background="@android:color/white"
    android:layout_gravity="bottom"
    app:behavior_hideable="true"
    app:behavior_peekHeight="100dp"
    app:layout_behavior="@string/BottomSheetBehaviorGoogleMapsLike"
   >

    <include
        layout="@layout/bottom_sheet_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"/>

</android.support.v4.widget.NestedScrollView>
