Android - 刪除viewpager中的額外空間

Question

我的ViewPager中有一個片段，但我希望它佔用所有空間。現在有一些空間（我將背景設置爲淡黃色），我猜想它可能是viewpager添加的默認填充，但我不確定。

我試圖將ViewPager上的填充設置爲-10dp，但它只能在左/右，而不是頂/底上工作，並且在某些設備上完全不起作用。

從根RelativeLayout（一合併標籤後）

<RelativeLayout 
     android:id="@+id/appointment_gallery_toolbar" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     android:layout_alignParentBottom="true" 
     android:background="#22000000" 
     >
