这是我的 Detailactivity 我在 MenuitemCompat 上收到一个错误,它说它无法解析符号 'MenuitemCompat'
这是我的detailfragment.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:bwq="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_share"
android:title="@string/action_share"
android:showAsAction="always"
/>
</menu>
谁能帮我解释一下我做错了什么是错的
已解决:我在这个问题上使用了第二个答案post
Want to use ViewPager, cannot get android.support.* to be recognized?
添加了 v4、v7 和 v13 库,并对我的导入进行了一些小的调整,一切正常
如果您尚未将此导入添加到您的 Detailactivity,您可能会收到该错误。
