I know how to apply a theme to the entire app, but where would I apply a theme to just one activity?
Solutip
You can apply a theme to any activity by including android:theme inside <aktivitas> the manifest file. For example:
<activity android:theme="@android:style/Theme.Dialog"><activity android:theme="@style/CustomTheme">
And if you want to set the theme programmatically, use it setTheme() before calling the method setContentView() and super.onCreate() inside the method onCreate().
