如何在Android上使用gps输出位置

我试图将位置输出到textview。 我使用了locationManager.toString（），但它只给我输出android.location.LocationManager@44ee7718。 我想输出像洛杉矶，CA 90501这样的位置。

LocationManager的代码：

LocationManager lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); //conversion Criteria criteria = new Criteria(); String bp = lm.getBestProvider(criteria, false); Location location = lm.getLastKnownLocation(bp); double lat = location.getLatitude(); double lon = location.getLongitude(); Geocoder gc = new Geocoder(this, Locale.getDefault()); List
 addresses = null; try{ addresses = gc.getFromLocation(lat, lon, 1); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } Address address = addresses.get(0); final String ad = address.getAddressLine(0); //ends here 

按钮的代码：

 Red.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub Intent intent = new Intent (Intent.ACTION_VIEW); intent.putExtra("sms_body", ad); intent.setType("vnd.android-dir/mms-sms"); startActivity(intent); } });

请尝试以下代码

 try { // Get the location manager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); Criteria criteria = new Criteria(); bestProvider = locationManager.getBestProvider(criteria, false); Location location = locationManager .getLastKnownLocation(bestProvider); double lat = location.getLatitude(); double lon = location.getLongitude(); Geocoder gc = new Geocoder(this); List
 lstAdd = gc.getFromLocation(lat, lon, 1); Address ad = lstAdd.get(0); String str = ad.getAddressLine(0); Toast tst = Toast.makeText(this, "Your current location is " + str, Toast.LENGTH_LONG); tst.show(); } catch (Exception e) { Toast tst = Toast.makeText(this,"Please check your gps settings", Toast.LENGTH_LONG); tst.show(); } 

希望这可以帮助。

调用适当的位置方法（getLatitude（），getLongitude（））

另外，为了转换为人类可读的名称，您需要使用GeoCoding
