Question

我为Admob编写了代码。这是我的layout.xml文件代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:id="@+id/relativeLayoutHomeParent"
tools:context=".Home" xmlns:app="http://schemas.android.com/apk/lib/com.google.ads">

<RelativeLayout
    android:id="@+id/relativeLayoutHomeTopBar"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true" >

    <TextView
        android:id="@+id/textView1"
        android:text="Home"
        style="@style/screen_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <ImageView
        android:id="@+id/imageViewHomeSettings"
        android:layout_width="22dp"
        android:layout_height="22dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:src="@drawable/set_settings"
        android:layout_marginRight="10dp" />

</RelativeLayout>

<View
    android:id="@+id/view1"
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:layout_below="@+id/relativeLayoutHomeTopBar"
    android:background="@drawable/shadow" />

<ListView
    android:id="@+id/listViewHome"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="#BDBDBD"
    android:dividerHeight="1dp"
    android:layout_below="@+id/view1" >
</ListView>

<com.google.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    app:adSize="BANNER"
    app:adUnitId="a1512f50d8c3692"
    app:loadAdOnCreate="true"
    app:testDevices="TEST_EMULATOR, TEST_DEVICE_ID" >
</com.google.ads.AdView>

        adView.destroy();

    super.onDestroy();
}
}

我想要屏幕底部的顶部栏（是黑色栏）。我也写了它，但它显示输出为上图。

另外，我不明白哪一个是admob横幅，顶部还是底部？任何人都可以解释这两个酒吧的区别。其实我是新手。这是我第一次为admob编写代码。请帮我学习一下。

Answer 1

两者都是admob banner。如果您希望在底部显示广告，请从Activity中删除以下代码，因为您已在xml中为底部添加了代码。

adView = new AdView(this, AdSize.BANNER, "a1512f50d8c3692");
RelativeLayout layout = (RelativeLayout)findViewById(R.id.relativeLayoutHomeParent);
layout.addView(adView);
adView.loadAd(new AdRequest());

Answer 2

只需删除它：

adView = new AdView(this, AdSize.BANNER, "a1512f50d8c3692");
RelativeLayout layout = (RelativeLayout)findViewById(R.id.relativeLayoutHomeParent);
layout.addView(adView);
adView.loadAd(new AdRequest());

您的xml布局中已经有了一个adView。

相反，这样做：

adView = (AdView) findViewById(R.id.adView);
adView.loadAd(new AdRequest());

但是，您可能希望在加载广告之前修改该AdRequest。这实际上是可选的，取决于您，但如果您这样做，您的收入（据称）会增加。

而且，在SO中复制粘贴代码之前，请先格式化它。在Eclipse中，您只需按Ctrl + Shift + F

即可

Admob横幅不在屏幕的底部
