Java 为什么我的GridView在最后被切断？

在上图中，底部的项目像红色箭头一样被切断。 也许Gridview的大小就是整个屏幕，而NavigationBottomView似乎覆盖了Gridview的一部分。我想指定GridView从屏幕顶部到BottomNavigationView顶部的高度

下面是我的xml代码

1> 带有NavigationBottomView（Home.xml）的主屏幕xml代码

5> 通过自定义ArrayAdapter（SiteAdapter.java）创建的SideAdapter代码

如果您能阅读我提出的问题并给他们一些建议，我将不胜感激。

之所以如此，是因为您用xml设置了FrameLayout height 520dp

设置frameLayout高度匹配，并使用上面的android:layout=“@+id/navigation”

试试这个代码

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       android:layout_above="@+id/navigation"
        android:orientation="horizontal">
       <OtherViews.../>
    </FrameLayout>
    <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="?android:attr/windowBackground"
        app:menu="@menu/navigation">
    </android.support.design.widget.BottomNavigationView>
</RelativeLayout>

我想要的部分已解决。非常感谢。但是为什么主屏幕会像上面显示的链接图片一样被破坏呢？
