【總結備用】 Android中通過GPS或NetWork擷取當前位置的經緯度

今天在Android項目中要實現一個通過GPS或NetWork來擷取當前移動終端裝置的經緯度功能。要實現該功能要用到Android Framework 中的 LocationManager 類。下面我就直接貼上主要的代碼說明如何?通過GPS或NetWork來擷取即時位置的經緯度。

private double latitude=0.0;private double longitude =0.0;LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location != null){latitude = location.getLatitude();longitude = location.getLongitude();}}else{LocationListener locationListener = new LocationListener() {// Provider的狀態在可用、暫時不可用和無服務三個狀態直接切換時觸發此函數@Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {}// Provider被enable時觸發此函數，比如GPS被開啟@Overridepublic void onProviderEnabled(String provider) {}// Provider被disable時觸發此函數，比如GPS被關閉 @Overridepublic void onProviderDisabled(String provider) {}//當座標改變時觸發此函數，如果Provider傳進相同的座標，它就不會被觸發 @Overridepublic void onLocationChanged(Location location) {if (location != null) {   Log.e("Map", "Location changed : Lat: "  + location.getLatitude() + " Lng: "  + location.getLongitude());   }}};locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,1000, 0,locationListener);   Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);   if(location != null){   latitude = location.getLatitude(); //經度   longitude = location.getLongitude(); //緯度}   }

同時別忘了在AndroidManifest.xml檔案中加入如下許可權：

<!-- 串連互連網Internet許可權 --><uses-permission android:name="android.permission.INTERNET" /><!-- GPS定位許可權 --><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
