android webview將無法正常工作

Question

當我在android webview中加載YouTube視頻網址時，我有點掙扎。我將該特定YouTube視頻鏈接的嵌入代碼加載到網絡視圖中。我成功加載。這裏我的問題是，我必須加載超過10個鏈接，所以我使用scrollview（我也使用listview）來顯示加載的鏈接。當我滾動的佈局，它放置在頁眉佈局，也沒有正確加載。在這裏我發佈我的代碼與我的輸出截圖任何一個請幫我解決這個問題。提前致謝。

改爲RelativeLayout使用LinearLayout（垂直視圖）。

 <?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

     android:scrollbars="none" > 

     <LinearLayout

      android:layout_marginTop="2dip" > 

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

       android:layout_below="@+id/web" /> 

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

     </LinearLayout> 
    </ScrollView> 

</LinearLayout>
