推荐答案
pressing返回键杀死你当前活动。用户不希望它被保存为有没有办法去前进。
Pressing the back key kills your current activity. A user would not expect it to be saved as there is no way to go "Forward" .
您可以保存您的活动的共享preferences的重要组成部分或一个数据库时，你preSS回来了，它恢复到previous状态，当活动下次启动它将使IM pression，它是保存
You can save the important parts of your activity in SharedPreferences or a database when you press back and restore it to its previous state when the activity next starts which would give the impression that it was "saved"
