推荐答案

在Android的活动都存储在堆栈叫活动栈，当你去到下一个活动它添加到堆栈，当你回到你弹出最后一个元素从堆栈中并没有什么点它了，所以不破坏只是浪费空间！

Activities in android are stored in a Stack called activity-stack, when you go to next Activity it's added to the stack, when you go back you pop last element from stack and nothing points at it any more, so not destroying is just waste of space!

即使你覆盖后退按钮启动previous活性 noHistory 或 clearTop 标志，目前活动将被销毁。

Even if you override the back button to launch previous activity with noHistory or clearTop flag, current activity would be destroyed.

我建议你阅读更多关于活动周期

I suggest that you read more on activity lifecycle
