            app:fabSize="normal">

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

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

我希望带有数据的线性布局位于“textViewAppBar”下方。我试图实现一个RelativeLayout，但它不起作用。现在，数据显示为完整布局，但我希望将其放在“textViewAppBar”下方，但 SwipeRefreshLayout 应为 match_parent，有什么建议吗？谢谢:-)

app:layout_behavior 应该添加到 CoordinatorLayout 的直接子级中。

所以你应该将 app:layout_behavior="@string/appbar_scrolling_view_behavior" 从 NestedScrollView 移动到 SwipeRefreshLayout。

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

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

    <android.support.v4.widget.SwipeRefreshLayout 
        android:id="@+id/swipe_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fillViewport="true">
            ...
        </android.support.v4.widget.NestedScrollView>

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

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