问题描述
我有像这样实现 ViewPager 的 Android 应用程序:
I have Android application with ViewPager implemented like this :

我不知道如何在 ViewPager 下实现 AdView.我试图以编程方式和 xml 将 AdView 放在 ViewPager 下面.没有错误,但没有展示广告.
I don't know how to implement AdView below the ViewPager. I have tried to put AdView below the ViewPager programmatically and in xml. There is no errors but ads are not showing.
我的 xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_alignParentBottom="top"
android:layout_height="0dp"
android:layout_weight="1"/>
<com.google.ads.AdView
android:id="@+id/ad"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_below="@+id/pager"
ads:adSize="BANNER"
ads:adUnitId="@string/admob_publisher_id"
ads:loadAdOnCreate="true" >
</com.google.ads.AdView>
推荐答案
好的,你有几个问题.
- 方向仅与 LinearLayout 相关.
- layout_alignParentBottom 需要一个布尔值而不是top"
- layout_weight 仅与 LinearLayout 或 RelativeLayout 相关
您有 2 个选项.使用 RelativeLayout 但首先定义 AdView 并在上面定义 ViewPager 或使用 LinearLayout 并让 ViewPager 使用 layout_weight 填充未使用的空间.
You have 2 options. Use a RelativeLayout but define the AdView first with the ViewPager being defined as above it OR use a LinearLayout and have the ViewPager fill the unused space using layout_weight.
作为相对布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<com.google.ads.AdView
android:id="@+id/ad"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
ads:adSize="BANNER"
ads:adUnitId="@string/admob_publisher_id"
ads:loadAdOnCreate="true" />
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentTop="true"
android:layout_above="@+id/ad"
/>
</RelativeLayout>
或作为线性布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<com.google.ads.AdView
android:id="@+id/ad"
android:layout_width="match_parent"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="@string/admob_publisher_id"
ads:loadAdOnCreate="true" />
</LinearLayout>
我个人会选择 LinearLayout,感觉更简单.
Personally I'd go with the LinearLayout it feels simpler.
