意向的onDestroy（）一直被称为与后退按钮 [英] Intent onDestroy() always being called with back button

问题描述

我似乎有相反的问题的话题我所遇到的所有其他职务。其他人发现的onDestroy（）并不总是叫，但我觉得它的总是并立即

I appear to have the opposite issue to every other post on the topic I have come across. Others find that onDestroy() is not always called but I find it always and immediately is.

我检查是否被调用以下内容：

I am checking whether it is called with the following:

@Override
protected void onDestroy() {
    super.onDestroy();
    Log.d(TAG, "onDestroy");
}

本日志code要么单击后退或使用我的动作条按钮，这只是调用家庭活动作为一个意图后，立即触发。

This log code is triggered immediately after either clicking back or using my actionbar button which just calls the home activity as an intent.

我环顾四周，但大家都说生命周期应该是这样的：的http：//开发商。 android.com/images/activity_lifecycle.png

I have looked around but everyone says the lifecycle should look like this: http://developer.android.com/images/activity_lifecycle.png

此行​​为并不局限于单一的应用程序;我曾尝试下载一些例如code和增加在上面调试code才发现相同的行为。它也并不限于单个机器人版本;我曾尝试在模拟器中2.1和2.3，也4.0.2物理设备上。

This behaviour is not limited to a single app; I have tried downloading some example code and adding in the above debugging code only to find the same behaviour. It is also not limited to a single android version; I have tried 2.1 and 2.3 in the emulator and also 4.0.2 on a physical device.

什么，我可能是做错了任何想法？

Any ideas of what I might be doing wrong?

推荐答案

pressing 返回键居然挑起完成（）方法上您的活动，并导致你的活动是 paused-> stopped->摧毁的

pressing back key actually provokes finish() method on your activity, and it causes your activity to be paused->stopped->destroyed

所以在技术上如预期这种行为的功能。

so technically this behavior is functional as expected.
