SQL Datein in GridView

[Didi95]

Hi,
ich habe folgendes Problem:
Meine App fragt Serverdaten aus einer SQL Datenbank ab und gibt sie mir bislang in einer ListView untereinander aus. Nun muss ich diese Daten aber nebeneinander angezeigt bekommen. Ist es da sinnvoll eine Gridview zu nehmen oder kann ich einfach auch mehrere Listviews nebeneinander setzen und sie mir dann so anzeigen lassen?

Hier der Codefür die ListView:

package com.example.vertretung;



import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import org.apache.http.NameValuePair;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import com.example.vertretung.R;
import android.app.ListActivity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class AlleVertretungen extends ListActivity {
	// Progress Dialog
		private ProgressDialog pDialog;

		// Creating JSON Parser object
		JSONParser jParser = new JSONParser();

		ArrayList<HashMap<String, String>> productsList;

		// url to get all products list
		private static String url_all_products = "http://yourcloud.eichsfeld-gymnasium.de/app_neu/get_all_products.php?id=23";

		// JSON Node names
		private static final String TAG_SUCCESS = "success";
		private static final String TAG_PRODUCTS="products";

			// Hashmap for ListView
			productsList = new ArrayList<HashMap<String, String>>();

			// Loading products in Background Thread

		}
