AndroidManifest.xml 增加 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> public class ditu extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LocationManager locationManager; String serviceName=Context.LOCATION_SERVICE; locationManager=(LocationManager)this.getSystemService(serviceName); //查询条件 Criteria criteria=new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); criteria.setAltitudeRequired(false); criteria.setBearingRequired(false); criteria.setCostAllowed(true); criteria.setPowerRequirement(Criteria.POWER_LOW); String provider=locationManager.getBestProvider(criteria,true); Location location=locationManager.getLastKnownLocation(provider); updateWithNewLocation(location); //设置监听器，自动更新的最小时间为间隔1秒，最小位移变化超过5米 locationManager.requestLocationUpdates(provider, 1000, 5, locationListener); } private final LocationListener locationListener=new LocationListener(){ public void onLocationChanged(Location location) { updateWithNewLocation(location); } public void onProviderDisabled(String provider) { updateWithNewLocation(null); } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; private void updateWithNewLocation(Location location){ String latLongString; TextView myLocationText; myLocationText=(TextView)this.findViewById(R.id.myLocationText); if(location!=null){ double lat=location.getLatitude(); double lng=location.getLongitude(); latLongString="维度："+lat+"\n经度"+lng; }else{ latLongString="无法获取地理信息"; } myLocationText.setText("您所在位置为："+latLongString); } } 哈哈，只要手机开了GPS,你就能随时定位自己的位置，可惜显示出来的是经纬度，如果结合google API，那就能显示在地图上了。
