我需要在 ActivityRecognition 检测用户状态(每 3 分钟调用一次)之后获取用户的位置(通过 fusedlocation API)，例如 IN_VEHICLE、ON_FOOT、RUNNING 等。
在每个事件中，我需要定期间隔后的用户位置例如:
如果用户还在，则 setInterval(5*60*60*1000); 并检查下一个位置
不早于 5 小时更新。但是 ActivityRecognation 会每 3 分钟调用一次。
如果用户正在运行，则 setInterval(2*60*1000); 并在 2 分钟之前/之后检查下一次位置更新。但是 ActivityRecognation 会每 3 分钟调用一次。
如果用户正在运行，则每 1 分钟发送一次位置 如果用户正在驾车，则每 15 分钟发送一次位置。
我试图在类级别将 onConnected 中的 boolean 值 false 设置为 false 和 true。但它总是变为 true，因为整个 Intent 服务在 3 分钟后被调用。
if (startLocationFirst){
requestLocatonSetting(5*60*60*1000,3*60*60*1000,LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationAPIclient.connect();// RequestLocation and GoogleAPIClient won't call until device comes from another ActivityRecognation State running,walking etc. And keep Updating location every 5 hours.
}
我目前遇到的问题
startLocationFirst boolean 值，直到它来自另一个 ActivityRecognation 状态并继续更新 startLocationFirst 中设置的位置这是带有 FusedLocation 的 IntentService

最佳答案
我在与上面相同的代码中添加几行后执行此代码。
IntentService 中的类级别声明了 static int，因为 DectectedActivity.getType() 返回 int。 static int detectedActivity;if (activity.getConfidence() >= 75 && activity.getType()!=detectedActivity)就是这样。感谢@Pablo Baxter，他给了我一些应用逻辑。我在 IntentService 上测试了这个，但我需要在服务上测试它，这样我才能更新位置。很快就会更新.

我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
给定这段代码defcreate@upgrades=User.update_all(["role=?","upgraded"],:id=>params[:upgrade])redirect_toadmin_upgrades_path,:notice=>"Successfullyupgradeduser."end我如何在该操作中实际验证它们是否已保存或未重定向到适当的页面和消息？ 最佳答案 在Rails3中，update_all不返回任何有意义的信息，除了已更新的记录数(这可能取决于您的DBMS是否返回该信息)。http://ar.ru
我将应用程序升级到Rails4，一切正常。我可以登录并转到我的编辑页面。也更新了观点。使用标准View时，用户会更新。但是当我添加例如字段:name时，它不会在表单中更新。使用devise3.1.1和gem'protected_attributes'我需要在设备或数据库上运行某种更新命令吗？我也搜索过这个地方，找到了许多不同的解决方案，但没有一个会更新我的用户字段。我没有添加任何自定义字段。 最佳答案 如果您想允许额外的参数，您可以在ApplicationController中使用beforefilter，因为Rails4将参数
我真的很习惯使用Ruby编写以下代码:my_hash={}my_hash['test']=1Java中对应的数据结构是什么？ 最佳答案 HashMapmap=newHashMap();map.put("test",1);我假设？ 关于java-等价于Java中的RubyHash，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/22737685/
当我的预订模型通过rake任务在状态机上转换时，我试图找出如何跳过对ActiveRecord对象的特定实例的验证。我想在reservation.close时跳过所有验证!叫做。希望调用reservation.close!(:validate=>false)之类的东西。仅供引用，我们正在使用https://github.com/pluginaweek/state_machine用于状态机。这是我的预订模型的示例。classReservation["requested","negotiating","approved"])}state_machine:initial=>'requested
我正在尝试使用boilerpipe来自JRuby。我看过guide从JRuby调用Java，并成功地将它与另一个Java包一起使用，但无法弄清楚为什么同样的东西不能用于boilerpipe。我正在尝试基本上从JRuby中执行与此Java等效的操作:URLurl=newURL("http://www.example.com/some-location/index.html");Stringtext=ArticleExtractor.INSTANCE.getText(url);在JRuby中试过这个:require'java'url=java.net.URL.new("http://www
对于作为String#tr参数的单引号字符串文字中反斜杠的转义状态，我觉得有些神秘。你能解释一下下面三个例子之间的对比吗？我特别不明白第二个。为了避免复杂化，我在这里使用了'd'，在双引号中转义时不会改变含义("\d"="d")。'\\'.tr('\\','x')#=>"x"'\\'.tr('\\d','x')#=>"\\"'\\'.tr('\\\d','x')#=>"x" 最佳答案 在tr中转义tr的第一个参数非常类似于正则表达式中的括号字符分组。您可以在表达式的开头使用^来否定匹配(替换任何不匹配的内容)并使用例如a-f来匹配一
我目前正在使用以下方法获取页面的源代码:Net::HTTP.get(URI.parse(page.url))我还想获取HTTP状态，而无需发出第二个请求。有没有办法用另一种方法做到这一点？我一直在查看文档，但似乎找不到我要找的东西。 最佳答案 在我看来，除非您需要一些真正的低级访问或控制，否则最好使用Ruby的内置Open::URI模块:require'open-uri'io=open('http://www.example.org/')#=>#body=io.read[0,50]#=>"["200","OK"]io.base_ur
