为什么AD不能位于Android Tabbed活动的屏幕顶部？

概述我创建了一个标签式活动,我使用 android：layout_alignParentTop =“true”设置了位于屏幕顶部的名为android：id =“@ id / adView”的AD. 运行应用程序后,我发现四个选项卡位于屏幕顶部.如何让AD位于Tab的上方？谢谢！ 当前 我希望 activity_main.xml中 <RelativeLayout xmlns:android="http 我创建了一个标签式活动,我使用 android：layout_alignParenttop =“true”设置了位于屏幕顶部的名为androID：ID =“@ ID / adVIEw”的AD.

解决方法 原因是您的布局位于Actionbaractivity内部,当您设置布局时,它将始终位于 *** 作栏中(在您的情况下是标题栏和选项卡). 要实现您想要的功能,请创建自己的自定义标题栏和标签. 总结
