How to enable back button of phone to go back to previous activity without enabling back button icon on action bar?
问题
假设我从当前活动切换到另一个活动，然后需要通过手机上原本存在的返回按钮回到先前的活动，同时还有一个主页按钮和菜单按钮。我已经禁用了我的操作栏，并且不想启用它。我也不想在我的活动中创建一个代表返回的图标。
请帮忙！

Suppose I move to another activity from my current one and then I need to go back to previous activity by pressing the back button originally present in the phone along with a home button and menu button. I have disabled my Action Bar and I don't want to enable it. Nor I want to create an icon in my activity that represents back.
Please Help!
