为标签RelativeLayout找到了意外的命名空间前缀“app” – Android?

前端之家收集整理的这篇文章主要介绍了为标签RelativeLayout找到了意外的命名空间前缀“app” – Android?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我需要在ScrollView中使用BottomSheetBehavior但是我说:
Unexpected namespace prefix "app" found for tag RelativeLayout

app:behavior_hideable="true"
app:behavior_peekHeight="80dp"

这是我的xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.CoordinatorLayout>

解决方法

我有同样的问题.只需将底页布局分成单独的文件即可.并通过“include”标签将其包含在主布局中.
