java - requestLocationUpdates 参数

Question

这就是 requestLocationUpdates 的样子(我使用它的方式):

requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)

我的问题是 minTime 和 minDistance 之间的逻辑关系是 OR 还是 AND。如果 minTime 已经过去，它是否会等待 minDistance？

或或与

Answer 1

documentation on requestLocationUpdate()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

因此，如果您指定非 0 值，则必须满足这两个参数才能收到更新。
