我做了一个 geolocation 程序，该程序能正常运行，但总是循环持续显示toast。代码如下：package com.application.geocoding;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
import android.app.Activity;
import android.os.Bundle;
import android.content.Context;
import android.location.Address;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.widget.TextView;
import android.widget.Toast;
public class main extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
geoLocation();
}
public void geoLocation()
{
LocationManager locationManager =(LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
//makeUseOfNewLocation(location);
updateWithNewLocation(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {
Toast.makeText(main.this,"Network Enabled",Toast.LENGTH_SHORT ).show();
}
public void onProviderDisabled(String provider) {
Toast.makeText(main.this,"Network Disabled",Toast.LENGTH_SHORT ).show();
}
};
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
}谁知道我应该把这一行放在哪儿？locationManager.removeUpdates(locationListener);那么它就会只运行一次？
