GPS位置更新参数

Question

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

此代码用于使用GPS获取位置但当两个条件获得满意（1秒和1米）或仅一个时，它会更新位置吗？

Answer 1

阅读javadoc，它说：

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

Answer 2

正如Tooltip / Javadoc所说：

 Parameters
       provider  the name of the provider with which to register 
       minTime  minimum time interval between location updates, in milliseconds 
       minDistance  minimum distance between location updates, in meters 

让我们看看你的价值观：1s，1m：
如果最后一秒和现在之间的距离大于一米，则位置每秒更新一次 位置每米更新一次，如果最后一次更新是至少一秒钟。

TL; DR：这是AND，只有两者都是真的才会更新位置。
