我是 Android 编程新手，遇到了一个简单的 XML 问题。我正在尝试将我的一项空 Activity 变成全屏 Activity 。我尝试添加这行代码 android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 进入我的 android list 文件，最终导致我的应用程序在启动时崩溃。
如果这也有帮助，我的受影响 Activity 的 java 文件将扩展 AppCompatActivity。我看到其他一些帖子提到这会产生问题，但我无法解决我的问题。
请帮我解决这个问题，同时让 Activity 全屏显示。任何帮助表示赞赏。谢谢!
XML
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"

android:theme="@style/Theme.AppCompat.Light">

android:label="Marks Calculator">
