Android GPS定位仪

此代码用于使用GPS获取位置，但当两个条件都满足（1秒和1米）或仅满足一个条件时，它将更新位置？阅读javadoc，它说：

glocManager  = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        glocListener = new MyLocationListenerGPS();
        glocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                1000 * 1,  // 1 Sec        
                1,         // 1 meter           
                glocListener);

正如工具提示/Javadoc所说：

The minDistance parameter can also be used to control the frequency of location updates. 
If it is greater than 0 then the location provider will only send your application an update when the location has changed by at least minDistance meters, 
AND at least minTime milliseconds have passed

让我们看看你的价值观：1秒，1米：
如果上一秒到现在的距离大于一米，则位置每秒更新一次。
如果上次更新至少在一秒钟前，则位置每米更新一次

TL；医生：而且，只有当两者都是真的时，位置才会更新。

这意味着当双方都满意时，我才会得到更新
