Gps简单更新

package gps.test;

import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.Toast;

public class GPS extends Activity {
private LocationManager lm;
private LocationListener locationListener;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

// ---use the LocationManager class to obtain GPS locations---
lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

locationListener = new MyLocationListener();

lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1,
locationListener);
}

private class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location loc) {
if (loc != null) {
Toast.makeText(
getBaseContext(),
"Location changed : Lat: " + loc.getLatitude()
+ " Lng: " + loc.getLongitude(),
Toast.LENGTH_SHORT).show();
}
}

@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}

@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
}
你一定记得要移动一下啊，不过最好还是设置一下参数该成1秒1000 另一个为0也可以
