指定位置管理器在 Android 中广播当前位置的时间间隔
有没有办法指定位置管理器广播当前位置的时间间隔？
我正在使用一种名为 startListening 的方法：
public void startListening() {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0,
this
);
}
谢谢
Is there any way to specify the time intervals that the Location Manager broadcasts the current location?
I am using a method called startListening:
public void startListening() {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0,
this
);
}
Thanks

public void requestLocationUpdates (Stringprovider, long minTime, float minDistance, LocationListenerlistener, Looperlooper)注册当前活动，由指定的提供程序定期通知。将定期使用当前位置或状态更新来调用所提供的 LocationListener。
可能需要一段时间才能收到最新位置。如果需要立即位置，应用程序可以使用 getLastKnownLocation(String) 方法。
如果用户禁用提供程序，更新将停止，并且将调用
onProviderDisabled(String)方法。一旦再次启用提供程序，就会调用 onProviderEnabled(String) 方法，并且位置更新将再次开始。可以使用
minTime和minDistance参数控制通知的频率。如果minTime大于 0，LocationManager 可能会在位置更新之间休息minTime毫秒以节省电量。如果minDistance大于 0，则仅当设备移动minDistance米时才会广播位置。要尽可能频繁地获取通知，请将这两个参数都设置为 0。后台服务应谨慎设置足够高的
minTime，以便设备不会因保持 GPS 或无线电而消耗太多电量一直开着。特别是，不建议使用低于 60000ms 的值。提供的Looper用于实现回调机制。

Periodically, the supplied LocationListener will be called with the current Location or with status updates.
It may take a while to receive the most recent location. If an immediate location is required, applications may use the getLastKnownLocation(String) method.
In case the provider is disabled by the user, updates will stop, and the
onProviderDisabled(String)method will be called. As soon as the provider is enabled again, the onProviderEnabled(String) method will be called and location updates will start again.The frequency of notification may be controlled using the
minTimeandminDistanceparameters. IfminTimeis greater than 0, the LocationManager could potentially rest forminTimemilliseconds between location updates to conserve power. IfminDistanceis greater than 0, a location will only be broadcasted if the device moves byminDistancemeters. To obtain notifications as frequently as possible, set both parameters to 0.Background services should be careful about setting a sufficiently high
minTimeso that the device doesn't consume too much power by keeping the GPS or wireless radios on all the time. In particular, values under 60000ms are not recommended.The supplied Looper is used to implement the callback mechanism.

Throws
IllegalArgumentExceptionif provider is null or doesn't existIllegalArgumentExceptionif listener is nullIllegalArgumentExceptionif looper is nullSecurityExceptionif no suitable permission is present for the provider.minTime ：通知的最小时间间隔，以毫秒为单位。该字段仅用作节省电量的提示，位置更新之间的实际时间可能大于或小于该值。
minDistance：通知的最小距离间隔，以米为单位
minTime : the minimum time interval for notifications, in milliseconds. This field is only used as a hint to conserve power, and actual time between location updates may be greater or lesser than this value.
minDistance: the minimum distance interval for notifications, in meters
// 60000 是 1 分钟，100 是公里
上面有 9000（九秒）和 500（如果位置移动超过 500 公里）
// 60000 Is 1 Minute and 100 is KM
Above you have 9000 (Nine Seconds) and 500 which is if the location has moved more than 500KM
