我真的不知道会发生什么，我可以建立项目但是当我在手机或模拟器上运行应用程序时，我得到了这个！ 如果有人知道解决方案，那就太棒了！

尝试在MainActivity扩展程序中将Activity更改为AppCompatAvtivity。
如果仍无法正常工作，请将父主题更改为AppTheme
<style name="Base.AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

我找到了解决方案，并且在你的styles-v21.xml中创建了以下主题（如果你导入了示例文件它应该已经存在了，但是如果它不存在，请创建它）：
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style
＆GT; 并在主要活动部分的清单中调用它，如下所示（删除我之前突出显示的行并将其放在其位置）：
android:theme="@style/AppTheme.NoActionBar">
