You can use location state changed receiver to know when user manually turns of location GpsReceiver.java

public class GpsReceiver extends BroadcastReceiver {
    private final LocationCallBack locationCallBack;

    /**
     * initializes receiver with callback
     * @param iLocationCallBack Location callback
     */
    public GpsReceiver(LocationCallBack iLocationCallBack){
            this.locationCallBack = iLocationCallBack;
    }

    /**
     * triggers on receiving external broadcast
     * @param context Context
     * @param intent Intent
     */
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().matches("android.location.PROVIDERS_CHANGED")) {
            locationCallBack.onLocationTriggered();
        }
    }
}

Create an interface to communicate GPS changes to Activity

public interface LocationCallBack {
    /**
     * on Location switch triggered
     */
    void onLocationTriggered();
}

Register receiver in onCreate() of Activity to start listening to GPS state changes

public void onCreate(Bundle savedInstance){
//---
registerReceiver(new GpsReceiver(new LocationCallBack() {
            @Override
            public void onLocationTriggered() {
                //Location state changed
            }
        }), new IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION));
//---
}
