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 获取位置但是当两个条件都满足（1 秒和 1 米）或只有一个时它会更新位置？

正如工具提示/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

让我们取你的值：1s，1m：
如果上一秒和现在之间的距离大于一米，则位置每秒更新一次。
如果上次更新至少在一秒前，则位置每米更新一次。

TL;DR：它是 AND，如果两者都为真，则仅更新位置。

阅读它说的javadoc：

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
