android - 使所有 fragment 位于横幅广告上方

Question

我在 MainActivity 中有 3 个 Fragments，它们都显示在 MainActivity 布局中，我在进度条下方有一个横幅广告(均位于底部) ，所以我想要的是所有fragment都放在banner和进度条上方，有什么解决办法吗？？

这是完整的activity_main布局(以及我在评论部分描述的解决方案):

<android.support.v4.widget.DrawerLayout

            </android.support.v7.widget.Toolbar>

            <android.support.design.widget.TabLayout

                </com.google.android.gms.ads.AdView>
            </LinearLayout>


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


    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/primary_color"
        app:headerLayout="@layout/nav_header"

        app:itemTextColor="@color/text_drawer_color"
        app:menu="@menu/drawer_menu" />
</android.support.v4.widget.DrawerLayout>

这是 fragment 的完整布局:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="@color/tan_background"
>



<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    android:layout_margin="4dp"

    >

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
    android:background="@color/tan_background"
    android:divider="@color/tan_background"
    android:dividerHeight="8dp"
    android:drawSelectorOnTop="true"
    android:focusable="true"
    android:orientation="vertical"
    android:nestedScrollingEnabled="true"

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

感谢您的帮助:)

既然您发布了更多代码，我发现它比我想象的还要容易。您根本不需要 RelativeLayout 。您可以使用单个 LinearLayout，并将 ViewPager 设置为权重 1，以便它填充空白空间。这是代码(未经测试，因此可能有拼写错误)。
