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?
