Android NavigationView显示在NavigationBar下，无法单击
如您所见，Android NavigationView显示在NavigationBar下，无法单击,android,material-design,navigationbar,navigationview,Android,Material Design,Navigationbar,Navigationview,如您所见，NavigationView的背景已设置为android:cliptoppadding='false'，可以在透明的NavigationBar下看到 但是NavigationView（NavigationDrawer）无法完全向上滚动到NavigationBar上方，如何解决这个问题 我希望列表项滚动到导航栏的顶部，这意味着最后一次发送不是在导航栏下方，而是在上方 layout/activity\u main.xml <?xml version="1.0" encoding

嗯，代码是这样运行的，我无法搜索有用的答案
欢迎任何意见，谢谢 您可以在导航中使用RecyclerView

多亏了mehrdad khosravi

然后，将布局文件从删除更改
name="android:windowTranslucentNavigation">true
从style.xml中的主题看一看“”@onurtaskin谢谢，根据代码计算确实是一个可行的解决方案，但是当用户隐藏/显示导航栏时会出现问题。它不能随NavigationBar
的隐藏/显示一起更改，因为我没有找到捕获NavigationBar
事件（t.t）的解决方案，所以我更愿意获得一个更改xml
文件的解决方案：）上面由onur taskin
创建的链接与我的问题不同，所以不能使用。您的意思是使用RecyclerView
保存NavigationView
中的所有项目？我想知道我可能需要处理所有项目的颜色一个接一个，就像？（因为每次点击后，项目都会改变颜色。）不管怎样，请在你高兴的时候写更多的细节，谢谢~是的。它的工作很好，而且吃饱了，但这是一条艰难的道路。为此，我编写了6个xml类和3个java类。当我不忙的时候，我会给你我的密码。你还需要那个答案吗？我没有更多的时间了
