You should use LocationManager and LocationListener classes. Use it like at Google Developers API Guide: create a LocationManager class:
您应该使用LocationManager和LocationListener类。像在Google Developers API指南中一样使用它：创建一个LocationManager类：
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
Create LocationListener with overriding onLocationChanged() method, that calls every time you change location:
创建LocationListener并覆盖onLocationChanged（）方法，每次更改位置时调用：
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
Register the LocationListener in LocationManager:
在LocationManager中注册LocationListener：
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
Notice, onLocationChanged() is called at the first time, when you register it with LocationManager
注意，当您使用LocationManager注册onLocationChanged（）时，第一次调用onLocationChanged（）
