Question

我正在使用HTML5WebView。

https://code.google.com/p/html5webview/source/browse/#svn%2Ftrunk%2FHTML5WebView%253Fstate%253Dclosed

我在HTML5WebView的底部添加了Google AdView，但AdView正在HTML5WebView的顶部显示。我希望HTML5WebView在获取AdView后只占用屏幕的其余部分。

我可以知道如何更改布局。我试过这样可能但没有运气。以下是AdView与HTML5WebView重叠的最新结果。

谢谢，亚历

这是我的

像这样包装LinearLayout和AdView：

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

    <LinearLayout android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="vertical"  >        
        <ProgressBar 
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_width="match_parent"
            android:layout_height="5dp"
            android:layout_gravity="center_vertical|center_horizontal"
            android:indeterminate="true"
               android:id="@+id/webViewProgressBar"/>

        <LinearLayout 
            android:id="@+id/error_console"
            android:orientation="vertical"          
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
        />
        <FrameLayout android:id="@+id/main_content"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
        />          
    </LinearLayout>

    <com.google.ads.AdView          
             android:id="@+id/adView"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             ads:adUnitId="a15302d1a9e05e7"
             ads:adSize="BANNER"
             ads:testDevices="TEST_EMULATOR"
             ads:loadAdOnCreate="true"/>

</LinearLayout>
