I think natually do it is straightforward, whether Intellij IDEA or Android Studio, I always click new Java class menu, and then typing the class name, press Enter to create. after that, I manually typing "extends Activity" in the class file, and then import the class by shortcut key. finally, I also manually override the onCreate() method and invoke the setContentView() method.

我认为自然是直截了当，无论是Intellij IDEA还是Android Studio，我总是点击新的Java类菜单，然后输入类名，按Enter键进行创建。之后，我在类文件中手动键入“extends Activity”，然后通过快捷键导入类。最后，我还手动覆盖onCreate（）方法并调用setContentView（）方法。
