Question

我的ViewPager中有一个片段，但是我想让它占用所有空间。现在有一些空间（我将背景设置为黄色），我怀疑它可能是viewpager添加的默认填充，但我不确定。

我尝试将ViewPager上的填充设置为-10dp，但它似乎只能在左/右，而不是顶部/底部工作，并且在某些设备上根本不起作用。

我的主要布局

从根padding（合并代码后面的那个）中删除RelativeLayout值

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