Question

下面的代码将AdView放在ListView的顶部，但我想要的是让屏幕底部的AdView和ListView占据屏幕的其余部分。

<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"

    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <!-- As the main content view, the view below consumes the entire
         space available using match_parent in both dimensions. -->
    <FrameLayout android:id="@+id/container" android:layout_width="match_parent"
        android:layout_height="match_parent" >


        <ListView
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:background="@color/lst_viw_bg"
            android:clipToPadding="false"
            android:id="@+id/listView"
            android:layout_gravity="center_horizontal|top"
            android:dividerHeight="10dp"
            android:divider="@android:color/transparent"
            android:scrollbarStyle="outsideOverlay"
            android:smoothScrollbar="true"
            android:scrollingCache="false"
            android:animationCache="false" />

        <com.google.android.gms.ads.AdView
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal|bottom"
            ads:adSize="BANNER"
            ads:adUnitId="@string/banner_ad_unit_id">
        </com.google.android.gms.ads.AdView>


        <ProgressBar
            android:id="@+id/progressBar"
            style="?android:attr/progressBarStyle"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_gravity="bottom|center_horizontal"
            android:visibility="gone"
            android:indeterminate="true" >
        </ProgressBar>

    </FrameLayout>


    <fragment android:id="@+id/navigation_drawer"
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:name="NavigationDrawerFragment"
        tools:layout="@layout/fragment_navigation_drawer" />

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

我希望它如下图所示：

将FrameLayout更改为RelativeLayout会导致我的应用程序在使用以下崩溃日志填充ListView时崩溃：

Answer 1

FrameLayout让您的视图可以互相叠加。我认为你应该改为使用RelativeLayout：

1 - 将FrameLayout更改为RelativeLayout

2 - 将此参数添加到AdView和ProgressBar：android：layout_below =“@ + id / listView”

如何将ListView下方的AdView对齐，两者都包含在FrameLayout中
