我已尝试按照 stackover 答案中的描述使用 Base.AppTheme 更改 Apptheme，但它不起作用。该应用正在显示 Youtube 片段、带有缩略图和标题的 recyclerview，但没有响应点击事件。
【问题讨论】：
【参考方案1】：您的应用程序有一个 AppCompat 主题
<application
android:theme="@style/AppTheme">
但是，您使用不是 AppCompat 主题后代的主题覆盖了 Activity（它扩展了 AppCompatActivity）
您可以像这样定义自己的全屏主题（注意父项中的 AppCompat=）
<style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
然后在 Activity 上设置它。
<activity android:name=".MainActivity"
android:theme="@style/AppFullScreenTheme" >
