工具栏和选项卡之间的线 [英] Line coming between toolbar and Tabs

问题描述

如何去除工具栏和tablayout之间的深线，我在google上搜索了有人说，给工具栏和tablayout添加一些高程，我做了但是没有用，在从工具栏和tablyout中删除高程之后，它是也不工作.请帮帮我:

tablayout_xml:

解决方案
我遇到了同样的问题，我使用的是 android:elevation="0dp" 但它没有用.在 xml 中的 AppBarLayout 中，设置 app:elevation="0dp" 而不是 android:elevation="0dp".

解决方案
I had the same problem, i was using android:elevation="0dp" but it didn't work. To the AppBarLayout in xml, set app:elevation="0dp" instead of android:elevation="0dp".
