scrollview在android中不起作用？

Question

我有根的佈局，我把背景圖像放到那個線性layout.I放置滾動視圖內線性layout.I想要內容在屏幕的底部，我也需要滾動視圖also.But我的內容總是起牀屏幕，無法獲取屏幕底部，我在滾動視圖中應用了權重，但是在滾動視圖中應用了權重，但滾動視圖無法正常工作。應如何處理scrollview.Thanks提前。 我在這裏嘗試下面的代碼。

你可以用這個試試。

<ScrollView 
     android:id="@+id/scrollView1" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:fillViewport="true" > 

讓我知道它是否有效。
