How to check if GPS is currently enabled or disabled

Using the method Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED), we can get the allowed location provider, GPS. To check if GPS is currently enabled or disabled, using the code:

        String GpsProvider = Settings.Secure.getString(getContentResolver(),
          Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        
        if(GpsProvider.equals("")){
         //GPS Disabled
         gpsState.setText("GPS Disable");
        }else{
         //GPS Enabled
         gpsState.setText("GPS Enable");
        }
