Android - 删除viewpager中的额外空间
问题描述:
我的ViewPager中有一个片段,但我希望它占用所有空间。现在有一些空间(我将背景设置为淡黄色),我猜想它可能是viewpager添加的默认填充,但我不确定。Android - 删除viewpager中的额外空间
我试图将ViewPager上的填充设置为-10dp,但它只能在左/右,而不是顶/底上工作,并且在某些设备上完全不起作用。
我主要布局

<RelativeLayout
android:id="@+id/appointment_gallery_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"

android:background="#22000000"
