以requestLocationUpdates为单位的更新间隔

Question

如何更新时间和距离间隔，或以不同的间隔再次调用requestLocationUpdates？

我的代码：

LocationManager locationManager = (LocationManager) activityObject.getSystemService(Context.LOCATION_SERVICE);

    cll = new CheckinLocationListener();

    LocationProvider gps = locationManager.getProvider(LocationManager.GPS_PROVIDER);

    // GPS

    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, timeDelay, distanceDelay, cll);

    Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

onLocationChanged：

if(location.getSpeed()>=0 && location.getSpeed()<= 3)
            {
                LocationsModel.this.distanceDelay = 25;
                LocationsModel.this.timeDelay = 10000;
            }
            else if(location.getSpeed()>=3 && location.getSpeed()<= 17)
            {
                LocationsModel.this.distanceDelay = 150;
                LocationsModel.this.timeDelay = 60000;
            }
            else if(location.getSpeed()>=17)
            {
                LocationsModel.this.distanceDelay = 300;
                LocationsModel.this.timeDelay = 240000;
            }

我想在下一次测量时使用新的间隔。

您需要首先调用locationManager.removeUpdates( cll );，然后使用新的时间间隔重新注册以获取更新。
