我怎么能getCurrent位置，也显示城市名 [英] how can i getCurrent location and display also city name
问题描述
我是新android系统中创建的当前位置，并显示其城市名称
i am new in android create current location and display its city name
我不知道关于code所以举一些例子说明创建当前位置，也显示城市名称thnks提前
i Have No idea About code so give some example to create current location and display also city name thnks in advance
推荐答案
使用此code从纬度和经度地名 STRONG>
Use this code to get location name from latitude and longitude:
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(context, Locale.getDefault());
try {
addresses = geocoder.getFromLocation(lat, lng, 1);
if(addresses.size()>0)
{
String cityName = addresses.get(0).getAddressLine(0);
String stateName = addresses.get(0).getAddressLine(1);
//Toast.makeText(getApplicationContext(),stateName , 1).show();
String countryName = addresses.get(0).getAddressLine(2);
}
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
用于获取当前位置使用以下步骤的纬度和经度：
for getting latitude and longitude of current location use following steps:
- 在您的项目名称创建新类它GPSTracker.java
-
复制和粘贴低于code到它
- Create new class in your project name it GPSTracker.java
copy and paste code below into it
公共类GPSTracker扩展服务实现LocationListener的{
public class GPSTracker extends Service implements LocationListener {
private final Context mContext;
// flag for GPS status
boolean isGPSEnabled = false;
// flag for network status
boolean isNetworkEnabled = false;
// flag for GPS status
boolean canGetLocation = false;
Location location; // location
double latitude=0;// latitude
double longitude=0; // longitude
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
// Declaring a Location Manager
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context;
getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) mContext
.getSystemService(LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
// no network provider is enabled
} else {
this.canGetLocation = true;
// First get location from Network Provider
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("Network", "Network");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Log.v("location ",""+location);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
// if GPS Enabled get lat/long using GPS Services
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
Log.v("location ",""+location);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return location;
}
/**
* Stop using GPS listener
* Calling this function will stop using GPS in your app
* */
public void stopUsingGPS(){
if(locationManager != null){
locationManager.removeUpdates(GPSTracker.this);
}
}
/**
* Function to get latitude
* */
public double getLatitude(){
if(location != null){
latitude = location.getLatitude();
}
// return latitude
return latitude;
}
/**
* Function to get longitude
* */
public double getLongitude(){
if(location != null){
longitude = location.getLongitude();
}
// return longitude
return longitude;
}
/**
* Function to check GPS/wifi enabled
* @return boolean
* */
public boolean canGetLocation() {
return this.canGetLocation;
}

现在，你想要得到的经度和纬度使用这种code：
Now where you want to get latitude and longitude use this code:
GPSTracker mTracker =新GPSTracker（MyActivity.this）;
双纬度= mTracker.getLatitude（）;
双LNG = mTracker.getLongitude（）;
GPSTracker mTracker = new GPSTracker(MyActivity.this); double lat = mTracker.getLatitude(); double lng = mTracker.getLongitude();
