package com.li.gprs;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

public class MyGPSDemo extends Activity {
private TextView msg = null;
private LocationManager locationManager = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.main);
this.msg = (TextView) super.findViewById(R.id.msg);
this.locationManager = (LocationManager) super
.getSystemService(Context.LOCATION_SERVICE);
this.locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, 1000, 1,
new LocationListenerImpl());
}
private class LocationListenerImpl implements LocationListener {
public void onLocationChanged(Location location) { // 位置改变
MyGPSDemo.this.msg.setText("用户位置发生改变，新的数据：\n" + "经度："
