需要 Android 上的 GPS 定位帮助

我需要一个简单的代码片段,可以执行以下操作。 我需要一个可以执行以下操作的函数。

  1. 检查 GPS 是否启用。如果未启用,则启用它。
  2. 检查当前位置,即获取经度和纬度
  3. 禁用 GPS。

我不需要像 LocationListener 那样持续更新位置。 15 分钟一次就可以了。 有人可以为此提供工作代码片段吗?

I need a simple code snippet which can do the following.
I need a function which can do the following.

  1. check if GPS is enabled. If not enabled, then enable it.
  2. check for the current location, i.e get longitude and latitude
  3. Disable the GPS.

I don't need the continuous location update like LocationListener. Just once in 15 mins is ok.
can anybody provide me working code snippet for this?

启用 GPS:

private void turnGPSOn(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

        if(!provider.contains("gps")){ //if gps is disabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3")); 
            sendBroadcast(poke);
        }
    }

禁用 GPS

 private void turnGPSOff(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

        if(provider.contains("gps")){ //if gps is enabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3")); 
            sendBroadcast(poke);
        }
    }

检查 GPS 是否打开。

if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
        buildAlertMessageNoGps();
    }

用于获取当前位置。

public void getCurrentLocation() {
        LocationManager locationManager;
        String context = Context.LOCATION_SERVICE;
        locationManager = (LocationManager) getSystemService(context);
        Criteria crta = new Criteria();
        crta.setAccuracy(Criteria.ACCURACY_FINE);
        crta.setAltitudeRequired(false);
        crta.setBearingRequired(false);
        crta.setCostAllowed(true);
        crta.setPowerRequirement(Criteria.POWER_LOW);
        String provider = locationManager.getBestProvider(crta, true);

        locationManager.requestLocationUpdates(provider, 1000, 0,
                new LocationListener() {
                    @Override
                    public void onStatusChanged(String provider, int status,
                            Bundle extras) {
                    }

                    @Override
                    public void onProviderEnabled(String provider) {
                    }

                    @Override
                    public void onProviderDisabled(String provider) {
                    }

                    @Override
                    public void onLocationChanged(Location location) {
                        if (location != null) {
                            double lat = location.getLatitude();
                            double lng = location.getLongitude();
                            if (lat != 0.0 && lng != 0.0) {
                                System.out.println("WE GOT THE LOCATION");
                                System.out.println(lat);
                                System.out.println(lng);
                                getAddress();                           
                            }
                        }

                    }

                });
    }

For enabling GPS:

private void turnGPSOn(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

        if(!provider.contains("gps")){ //if gps is disabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3")); 
            sendBroadcast(poke);
        }
    }

For disabling GPS

 private void turnGPSOff(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

        if(provider.contains("gps")){ //if gps is enabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3")); 
            sendBroadcast(poke);
        }
    }

To check GPS is on or not.

if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
        buildAlertMessageNoGps();
    }

For getting current location.

public void getCurrentLocation() {
        LocationManager locationManager;
        String context = Context.LOCATION_SERVICE;
        locationManager = (LocationManager) getSystemService(context);
        Criteria crta = new Criteria();
        crta.setAccuracy(Criteria.ACCURACY_FINE);
        crta.setAltitudeRequired(false);
        crta.setBearingRequired(false);
        crta.setCostAllowed(true);
        crta.setPowerRequirement(Criteria.POWER_LOW);
        String provider = locationManager.getBestProvider(crta, true);

        locationManager.requestLocationUpdates(provider, 1000, 0,
                new LocationListener() {
                    @Override
                    public void onStatusChanged(String provider, int status,
                            Bundle extras) {
                    }

                    @Override
                    public void onProviderEnabled(String provider) {
                    }

                    @Override
                    public void onProviderDisabled(String provider) {
                    }

                    @Override
                    public void onLocationChanged(Location location) {
                        if (location != null) {
                            double lat = location.getLatitude();
                            double lng = location.getLongitude();
                            if (lat != 0.0 && lng != 0.0) {
                                System.out.println("WE GOT THE LOCATION");
                                System.out.println(lat);
                                System.out.println(lng);
                                getAddress();                           
                            }
                        }

                    }

                });
    }
