这是我Detailactivity我爬MenuitemCompat它说,它无法解析符号错误“MenuitemCompat”MenuItemCompat无法解决
这是我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>
谁能帮我并向我解释我在做什么错是错的
解决:我对这篇文章使用了第二个答案 Want to use ViewPager, cannot get android.support.* to be recognized?
新增V4,V7和V13 libary的,并与我的一切都进口一些小的调整工作
以及进口android.support.v4.view。我得到一个未使用的导入和MenuItemCompat我仍然得不到解决符号 –
它适用于我。确保将其添加到您创建“ShareActionProvider”的活动中。 – krrish
我更新帖子我张贴洞活动,现在你可以看到我使用进口jet我得到的错误我告诉你的导入和MenuItemCompat –
