如何在线程中调用requestLocationUpdates?
问题描述:
我想从一个线程获取我的位置。 我代码:如何在线程中调用requestLocationUpdates?
LocationManager locationManager;
GeoPoint p;
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria cri = new Criteria();
String tower = locationManager.getBestProvider(cri, false);
Location location = locationManager.getLastKnownLocation(tower);
但如何调用requestLocationUpdates
更新的位置? 你能帮我吗?
答
您拥有开发者文档中的所有内容:Requesting Location Updates。
// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// 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 listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
如果在线程中调用LocationListener locationListener = new LocationListener(),则显示excel。 – mum
你会得到什么例外? Post logcat –
java.lang.RuntimeException:无法在未调用Looper.prepare()的线程内创建处理程序() – mum
