java - AdView 未出现在应用底部

Question

我正在尝试将 AdView 放在我的应用程序的底部。但是，当我测试我的应用时，我没有看到广告，也没有看到 AdView。

在我的 MainActivity 中，我用 2 个 fragment 替换 2 个 FrameLayout。因此 AdView 应出现在第三个 fragment 之后。

这是我的 main_activity.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/layout_id"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <FrameLayout
        android:id="@+id/fragment_content"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

    <FrameLayout
        android:id="@+id/fragment_content2"
        android:layout_width="fill_parent"
        android:layout_height="500dp" />

    <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:adSize="BANNER"
         ads:adUnitId="app_id"/>
</LinearLayout>

Main_activity.java

@Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main_activity);

        adView = (AdView) findViewById(R.id.adView);

        AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("5554:Perfect_One")
        .build();

        // Start loading the ad in the background.
        adView.loadAd(adRequest);

        myContext = this;

        fragmentManager = this.getFragmentManager();

        Fragment frag = new SortFeature();
        FragmentTransaction ft = fragmentManager.beginTransaction();
        ft.replace(R.id.fragment_content, frag);
        ft.commit();

        Fragment frag2 = new CardListView();
        FragmentTransaction ft2 = fragmentManager.beginTransaction();
        ft2.replace(R.id.fragment_content2, frag2);
        ft2.commit();

这是 CardListView fragment 使用的布局。

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listview"
android:layout_width="match_parent"
android:layout_height="500dp"
android:background="@drawable/background" />

这是我的日志:

Answer 1

最后，我成功了。问题是没有足够的空间来展示广告。

我的 CardListView fragment 的高度是 500dp。实在是太多了。我将其降低到 300dp，现在我可以正确地看到我的 Adview。
