<blockquote>

</blockquote>

No and yes. Use a timer if you're implementing it in a <a href="http://developer.android.com/reference/android/app/Service.html" rel="nofollow"><code>Service</code></a> or in an <a href="http://developer.android.com/reference/android/app/IntentService.html" rel="nofollow"><code>IntentService</code></a>. Otherwise, don't.

<blockquote>
 In every function where the user interacts with the app (basically all event handlers), call a method that resets the timer.
</blockquote>

That solution would be hard to maintain. 

You should have an <code>IntentService</code> (demonstrating article <a href="http://developer.android.com/guide/topics/fundamentals/services.html" rel="nofollow">here</a>) running in the background that can easily implement a <a href="http://developer.android.com/reference/java/util/TimerTask.html" rel="nofollow"><code>TimerTask</code></a> or a <a href="http://developer.android.com/reference/android/os/Handler.html" rel="nofollow"><code>Handler</code></a> and make the runnable code inside it fire a broadcast to your activities. In your activities you can easily add a <a href="http://developer.android.com/reference/android/content/BroadcastReceiver.html" rel="nofollow"><code>BroadcastReciever</code></a> and in that case you can log out the user if time is out. You can start your service when your application isn't visible to the user.

blocks|key|2814414|text|我就是这样做的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2814415|1)创建一个全局变量来表示时间日志|2814416|2)在每个活动的onStop调用期间，用当前时间更新全局变量。|2814417|3)在对每个活动进行onResume调用期间，将当前时间与全局变量时间进行比较，以查看已经过去了多少时间|2814418|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

This is how I would go about this:

1) Create a global variable to represent a time log

2) During the onStop call for each activity, update the global variable with the current time.

3) During the onResume call for each activity, compare the current time with the global variable time to see how much time has passed

blocks|key|2455615|text|这是我想为自己实现的东西。这里是我创建的一个“库”：https://github.com/zoltanersek/android-timeout-activity|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2455616|用法：|2455617|public+class+TestActivity+extends+TimeoutActivity+{

This is something that I wanted to implement for myself.
Here is a "library" I made: <a href="https://github.com/zoltanersek/android-timeout-activity" rel="nofollow">https://github.com/zoltanersek/android-timeout-activity</a>

Usage:

<pre><code>public class TestActivity extends TimeoutActivity {

@Override protected void onTimeout() {
 // logout
}

@Override protected long getTimeoutInSeconds() {
 return 15 * 60; // 15 minutes
}

}
</code></pre>

I'm looking to implement a feature that logs out the user after X minutes of inactivity. After going through a similar answer on SO, the suggested method seems to be to -

<ul>
<li>Have a timer running in the background. Schedule it to timeout after x minutes.</li>
<li>In every function where the user interacts with the app (basically all event handlers), call a method that resets the timer.</li>
</ul>

I can't think of anything better than this myself, but it's seems to be a huge pain even for a medium sized application that has 6-7 different screens and a whole bunch of UI components. Is there a better way to handle this?

Thanks, 
Teja.

我希望实现一个功能，在X分钟的不活动之后将用户注销。经过类似的回答后，建议的方法似乎是-让计时器在后台运行。把它安排在x分钟后超时。在用户与应用程序交互的每个函数中(基本上都是事件处理程序)，调用一个重置计时器的方法。我自己想不出比这更好的东西了，但即使对于一个拥有6-7个不同屏幕和大量UI组件的中型应用程序来说，这似乎也是一个巨大的痛苦。有更好的方法来处理这件事吗？谢谢,提亚。
