Question

我在自己的应用中集成Google AdMob广告时遇到问题。我使用导航抽屉布局，如下所示：

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<fragment
    android:id="@+id/navigation_drawer"
    android:name="pl.ntimobile.personalcoach.NavigationDrawerFragment"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:layout_gravity="start" />

当我将google AdMob广告放在片段下方时，就像这样：

(...)
android:layout_gravity="start" />

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

我在课堂上正确启动它，效果很好，但广告显示在屏幕中间，2）在导航抽屉上方，所以当我显示导航抽屉时，我无法点击任何一个内容。因此，当我尝试将广告和片段放在线性布局中时，我得到ClassCastException ...我的布局看起来像：

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <fragment
        android:id="@+id/navigation_drawer"
        android:name="pl.ntimobile.personalcoach.NavigationDrawerFragment"
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="match_parent"
        android:layout_gravity="start" />

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

我得到了，在我的logcat中：

Answer 1

好的，明白了。我正在尝试（通过mystake）使用NavigationDrawerFragment将广告放入LinearLayout，而不是使用容器。在RelativeLayout中放置带容器的广告可以解决问题：

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_ad_unit_id" >
    </com.google.android.gms.ads.AdView>

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@id/adView" />
</RelativeLayout>

<fragment
    android:id="@+id/navigation_drawer"
    android:name="pl.ntimobile.personalcoach.NavigationDrawerFragment"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:layout_gravity="start" />

就像我想要的那样工作。

Answer 2

使用

import android.widget.LinearLayout

而不是

import android.support.v4.widget.LinearLayout

将AdMob广告集成到导航栏中时出现ClassCastException
