Question

看到几个类似的线程，但没有相同或解决方案。

尝试将一个简单的示例项目放在一起，以了解navigationView的实现。

错误是按照标题，我被告知我必须使用appcompat主题。但据我所知，我正在使用一个！？

在我的样式文件中，＆＃34; Theme.AppCompat.Light.NoActionBar＆＃34;，并在清单中引用。

我确定我错过了一些简单的东西，但作为所有这个java-android malarkey的菜鸟，我的目光还没有看到它。

非常感谢有人指出我错过了什么!!

旁注...... 对我来说，一个样式问题导致我的应用程序崩溃似乎很奇怪，不应该是样式出现＆＃39;外观＆＃39;不是＆＃39;功能＆＃39; ？

Answer 1

您的基地res\values\styles.xml

还需要以下内容

<!-- Main Theme -->
    <style name="MainTheme" parent="Theme.AppCompat.Light.NoActionBar"
...
 >

Answer 2

发现它！因此，在创建我的应用程序的某个时刻，似乎出现了一个新文件夹：＆＃34; res / values-v21 / stles.xml＆＃39; 我不知道发生过这种情况，所以如果我的帖子在没有列出的情况下误导，那就道歉了。在那里，＆＃39; AppTheme＆＃39;再次定义，推翻我在res / values / styles.xml中创建的定义。

从那时起谷歌搜索并找到了关于此的文档.. https://developer.android.com/training/material/compatibility.html#Theme

感谢问谁提出了建议，希望我没有浪费你的时间。也许会有一些其他的菜鸟会发现这很有用！

你需要使用theme.appcompat主题 - 但我是，不是吗？
