Java 将Admob放入墙纸设置时出错

对不起，我是admob的新手，我把它放在了另一个简单的应用程序中，但我不能把它放在LiveWallper中。我得到一个com.google.android.gms.ads.adView不能被转换为android.preference.preference

这是我的livewallpaper_settings.xml：

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:key="livewallpaper_settings"
    android:title="@string/livewallpaper_settings" >

    <ListPreference
        android:entries="@array/livewallpaper_testpattern_names"
        android:entryValues="@array/livewallpaper_testpattern_prefix"
        android:key="livewallpaper_testpattern"
        android:summary="@string/livewallpaper_settings_summary"
        android:title="@string/livewallpaper_settings_title" />

    <CheckBoxPreference
        android:key="livewallpaper_movement"
        android:summary="@string/livewallpaper_movement_summary"
        android:summaryOff="Still test pattern"
        android:summaryOn="Moving test pattern"
        android:title="@string/livewallpaper_movement_title" />

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />

</PreferenceScreen>

除了首选项屏幕中的首选项之外，您不能有任何类型的视图。 建议不是一种偏好

此外，您的用户真的会将所有时间都花在应用程序的首选屏幕上吗？

谢谢您提供的信息！我不知道。。我如何将这类应用程序货币化？威廉
