java - 将 adView 嵌入 ListView fragment 中的 android 逻辑错误 - 最新的 admob sdk - 使用 XML 和 Java 进行了修订

Question

我终于让我的广告在我的 ListView fragment 中运行，但现在我遇到了一个奇怪的逻辑错误。问题似乎与跟踪广告的位置(位置 0)和列表中的其余项目有关。第一个项目被添加替换，点击列表中的任何项目进行更新，然后返回到项目列表。列表名称似乎乱序。

以下是我使用 adMob XML 代码和我的 ListFragment 类中的几行 java 所做的修订，

我的XML代码如下:

  <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      >
    <LinearLayout 
      android:id="@+id/adsContainer"
      android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"/>
    <com.google.android.gms.ads.AdView
      xmlns:ads="http://schemas.android.com/apk/res-auto"
      android:id="@+id/adView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      ads:adUnitId="ca-app-pub-9999999999999999999999999"
      ads:adSize="BANNER"/>
    <ListView
      android:id="@android:id/list"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      >
     </ListView>
     <ListView
       android:id="@android:id/empty"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:paddingLeft="4dp"
       android:paddingRight="4dp"
       android:text="@string/new_empty_desc" 
      >
      </ListView>
</

在我的类(class)公共(public)类 BxListFragment extends SherlockListFragment :

我正在尝试在上面的 ListFragment 中添加这段代码。目前我收到语法错误 findVuewById(int) undefined。我的问题是在我的 listfragment 中哪里可以最好地插入这段代码以将广告放置在上面的 XML 中？

<pre><code> /* * New ads Logic */ AdView adView = (AdView)this.findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .addTestDevice("TEST_DEVICE_ID") .build(); adView.loadAd(adRequest); </code></pre>

问题可能与使 0 成为特例有关，但数据源也有零元素。列表和适配器不再对齐。

将广告 View 放在页眉中可能会奏效。看这里: https://developer.android.com/reference/android/widget/ListView.html#addHeaderView%28android.view.View,%20java.lang.Object,%20boolean%29
