android - RequestLocationUpdates参数android

Question

我对这个参数感到困惑

locationManager.requestLocationUpdates(provider, 
                60000,
                10,
                listener);

下面是它如何执行location update listener。if time = 60000 AND distance = 10 那么它将执行或if time = 60000 OR distance = 10 然后它会执行。请帮我解决这个困惑。

Answer 1

根据 the docs :

The elapsed time between location updates will never be less than minTime

因此 minTime 优先。进一步说:

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

所以它应该是 if(time >= minTime AND dist >= minDistance)，意思是如果太早就不会检查距离。但是不要太认真地对待这些参数before JellyBeans .
