You can start the GPS by using

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    LocationListener locationListener = new CTLocationListener();
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 1.0f, locationListener);

To stop the gps provider use

locationManager.removeUpdates(locationListener);

I researched about this subject on all web sites. and I found this code like below. I tried its working.

Method-1

Enable GPS
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);
Disable GPS
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", false);
sendBroadcast(intent);

Method-2

 // If GPS is OFF
    private void turnGPSOn(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        if(!provider.contains("gps")){
            final Intent intent = new Intent();
            intent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
            intent.addCategory(Intent.CATEGORY_ALTERNATIVE);
            intent.setData(Uri.parse("3"));
            sendBroadcast(intent);
        }
    }
    // If GPS is ON
    private void turnGPSOff(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        if(provider.contains("gps")){
            final Intent intent = new Intent();
            intent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
            intent.addCategory(Intent.CATEGORY_ALTERNATIVE);
            intent.setData(Uri.parse("3"));
            sendBroadcast(intent);
        }
    }
