获取当前位置的经度和纬度的android [英] getting current location longitude and latitude in android
本文介绍了获取当前位置的经度和纬度的android的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我与这我得到位置的经度和纬度位置一流，但我的问题是，如果我改变我的当前位置的经度和纬度值不更新。
如果我存储我的家的位置在我的设备，然后我的应用程序正在采取一切相同的经度和纬度值是不听我的当前位置信息的时间。例如：我今天是在纽约，我发起了一个应用程序，该位置是我的家在新泽西州。

THis is my location class with this i am getting location longitude and latitude, but my problem is if i change my current location the longitude and latitude values are not updating.
if i store my home location in my device, then my app is taking every time the same longitude and latitude values it is not taking my current location details. ex: I was in new york today and I launched a app and the location was my home in new jersey.
public class GetLocation extends Activity {
protected LocationManager locationManager;
protected Button retrieveLocationButton;
Context mContext;
Double Longitude, Latitude;
String NetworkErrmsg = "", GpsErrmsg = "", ProviderErrmsg = "", NoNetworkmsg = "", GpsSuccesmsg = "", NetworkSuccesmsg = "";
public GetLocation(Context mContext) {
// TODO Auto-generated constructor stub
this.mContext = mContext;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void getLocationDetails() {
locationManager = (LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10, 100, new MyLocationListener());
boolean gps_enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean network_enabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!gps_enabled) {
GpsErrmsg = "No Gps Connectivity";
} else {
showCurrentLocation(LocationManager.GPS_PROVIDER);
GpsSuccesmsg = "Gps Enabled";
}
if (network_enabled && !gps_enabled) {
showCurrentLocation(LocationManager.NETWORK_PROVIDER);
NetworkSuccesmsg = "Network Provider Enabled. Please Enable your GPS settings to get exact onaround you list";
}
if (!gps_enabled && !network_enabled) {
NoNetworkmsg = "Please Enable your Network/GPS settings to get onaround you list";
}
}
protected void showCurrentLocation(String provider) {
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
Longitude = location.getLongitude
Latitude = location.getLatitude();
} else {
NoNetworkmsg = "Please Enable your Network/GPS settings to get onaround you list";
Longitude=null; Latitude=null;
}
}
private class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location location) {
System.out.println("Longitude " + location.getLongitude());
}
@Override
public void onStatusChanged(String s, int i, Bundle b) {
// Toast.makeText(GetLocation.this, "Provider status changed", Toast.LENGTH_LONG).show();
}
@Override
public void onProviderDisabled(String s) {
// Toast.makeText(GetLocation.this, "Provider disabled by the user. GPS turned off",Toast.LENGTH_LONG).show();
}
@Override
