How to Make a Custom ArrayAdapter for ListView

Question

I have to make a custom ArrayAdapter from the JSON response I'm getting. Here is my code from where I'm getting response and putting it in simple ArrayAdapter with android.R.layout.simple_list_item_1

ListView lv = (ListView) findViewById(R.id.list);

    try {

        HttpClient hClient = new DefaultHttpClient();
        HttpGet hGet = new HttpGet(
                "API HERE");
        ResponseHandler<String> rHandler = new BasicResponseHandler();
        data = hClient.execute(hGet, rHandler);

        JSONObject rootObj = new JSONObject(data);
        JSONObject searchObj = rootObj.getJSONObject("searchdata");
        JSONArray titlesObj = searchObj.getJSONArray("titles");
        JSONArray descsObj = searchObj.getJSONArray("desc");
        JSONArray linksObj = searchObj.getJSONArray("links");

        String[] a = new String[titlesObj.length()];

        String[] b = new String[descsObj.length()];

        String[] c = new String[linksObj.length()];

        for (int i = 0; i < titlesObj.length(); i++) {
            String title = titlesObj.getString(i);
            a[i] = title;
        }

        for (int i = 0; i < descsObj.length(); i++) {
            String desc = descsObj.getString(i);
            b[i] = desc;
        }

        for (int i = 0; i < linksObj.length(); i++) {
            String link = linksObj.getString(i);
            c[i] = link;
        }

        ArrayList<String> al = new ArrayList<String>();
        for (int i = 0; i < linksObj.length(); i++)

        {
            al.add(" " + a[i] + " " + b[i] + "" + c[i] + "");
        }
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                MainActivity.this, android.R.layout.simple_list_item_1, al);

        lv.setAdapter(adapter);

    } catch (Exception e) {

    }

Here, is the screenshot of my view:

OUTPUT of my CODE

I want to show the view which has three TextView one for the title, another one for URL and the last one for description.

Any help will be appreciated.

Make a Custom Adapter. Set that adapter to your listview. Your Adapter class should extend ArrayAdapter. In getView() inflate your custom xml with 3 textviews . Use a viewholder for performance.

Hers's an example http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/. Hers's a bit more to listview http://www.youtube.com/watch?v=wDBM6wVEO70.

how to set json parsed data in a listview and then adding search functionality in it. Have a look at the answer. I have used hashmap and displayed data in listview accordingly with search on listview items. Modify the same according to your needs.

The example of androidhive is using HashMap and the problem with hashmap is that it replaces the old value with the new one and by this example I get only the last value in the listview. Can you tell me how we can recover that problem. – Anupam Feb 28 '13 at 15:32

Anupam, you can place the small data like

   al.add(" " + apple + " " + ball + "" +cat + "");

in single row in single line. If u want to keep that much data(above mentioned in image in one single row) in single row in single line is not possible.
