android webview将无法正常工作

Question

当我在android webview中加载YouTube视频网址时，我有点挣扎。我将该特定YouTube视频链接的嵌入代码加载到网络视图中。我成功加载。这里我的问题是，我必须加载超过10个链接，所以我使用scrollview（我也使用listview）来显示加载的链接。当我滚动的布局，它放置在页眉布局，也没有正确加载。在这里我发布我的代码与我的输出截图任何一个请帮我解决这个问题。提前致谢。

改为RelativeLayout使用LinearLayout（垂直视图）。

 <?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

<TextView 
    android:id="@+id/header_backButton" 
    android:layout_width="fill_parent" 
    android:layout_height="60dip" 
    android:background="#333322" 
    android:gravity="center_horizontal" 
    android:text="HOME" 
    android:textStyle="bold" 
    android:textSize="30sp" 
    android:textColor="#FFFFFF" 
    /> 

    <ScrollView 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@+id/header" 
     android:scrollbars="none" > 

     <LinearLayout 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:orientation="vertical" 
      android:layout_marginTop="2dip" > 

      <WebView 
       android:id="@+id/web" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" /> 

      <WebView 
       android:id="@+id/web1" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:layout_below="@+id/web" /> 

      <WebView 
       android:id="@+id/web2" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:layout_below="@+id/web1" /> 

      <WebView 
       android:id="@+id/web3" 
       android:layout_width="fill_parent"

     </LinearLayout> 
    </ScrollView> 

</LinearLayout>
