由于某种原因,onLocationChanged不刷新,我只做了一次GPS应用,它只在应用启动时运行一次。onLocationChanged只调用一次,不刷新
这里是我的代码: “位置已更改”
public BackgroundLocationService() {
super("myintentservice");
locManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
Criteria crt = new Criteria();
crt.setAccuracy(Criteria.ACCURACY_FINE);
String bestProvider = locManager.getBestProvider(crt, true);
boolean gps_enabled;
boolean network_enabled;
boolean best_enabled;
gps_enabled = locManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
best_enabled = locManager.isProviderEnabled(bestProvider);
if (best_enabled) {
locManager.requestLocationUpdates(bestProvider, 15000, 20, locListener);
Log.i(TAG, "Best enabled: " + bestProvider);
} else {
Log.i("Location Provider: ", "best not enabled: " + bestProvider);
if (gps_enabled) {
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
Log.i(TAG, "gps enabled!");
}
if (network_enabled) {
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
Log.i(TAG, "network enabled!");
}
}
}
class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
if (location != null) {
//locManager.removeUpdates(locListener);
longitude = Double.toString(location.getLongitude());
latitude = Double.toString(location.getLatitude());
Log.i(TAG,"Location has CHANGED!");
}
}
public void onProviderDisabled(String arg) {}
public void onProviderEnabled(String arg) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
}
的消息仅在每个应用程序启动时显示一次。 即时消息在办公室,但我可以移动距离我的位置至少5-10米,并且所有提供商都已启用,因此它必须正常,不是吗?
任何想法?
我认为你应该指定较少米:locManager.requestLocationUpdates(bestProvider,15000,5,locListener); (例如) – SolArabehety
