how to display fetched json data into listview using baseadapter

Question

I am new to android and java.Recently I am having problem with displaying fetched json data into listview using baseadapter. At first I have used this code

Answer 1

First u need t create row_listitem.xml file like:

Now, u need to create Custom BaseAdapter like:

  public class BaseAdapter2 extends BaseAdapter {

private Activity activity;
// private ArrayList<HashMap<String, String>> data;
private static ArrayList title,notice;
private static LayoutInflater inflater = null;

public BaseAdapter2(Activity a, ArrayList b, ArrayList bod) {
    activity = a;
    this.title = b;
    this.notice=bod;

    inflater = (LayoutInflater) activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}

public int getCount() {
    return title.size();
}

public Object getItem(int position) {
    return position;
}

public long getItemId(int position) {
    return position;
}

public View getView(int position, View convertView, ViewGroup parent) {
    View vi = convertView;
    if (convertView == null)
        vi = inflater.inflate(R.layout.row_listitem, null);

    TextView title2 = (TextView) vi.findViewById(R.id.txt_ttlsm_row); // title
    String song = title.get(position).toString();
    title2.setText(song);


    TextView title22 = (TextView) vi.findViewById(R.id.txt_ttlcontact_row2); // notice
    String song2 = notice.get(position).toString();
    title22.setText(song2);

return vi;

}

}

Now, u can set up your main activity like:

public class MainActivity extends Activity {

ArrayList title_array = new ArrayList();
ArrayList notice_array = new ArrayList();
ListView list;
BaseAdapter2 adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    list = (ListView) findViewById(R.id.listView1);
    new TheTask().execute();
}

class TheTask extends AsyncTask {

    @Override
    protected String doInBackground(Void... params) {
        String str = null;
        try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(
                    "http://10.0.2.2/BSDI/show.php");
            HttpResponse response = httpclient.execute(httppost);
            str = EntityUtils.toString(response.getEntity());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return str;

    }



@Override
protected void onPostExecute(String result) {

    super.onPostExecute(result);

    String response = result.toString();
    try {


        JSONArray new_array = new JSONArray(response);

        for (int i = 0, count = new_array.length(); i < count; i++) {
            try {
                JSONObject jsonObject = new_array.getJSONObject(i);
                title_array.add(jsonObject.getString("title").toString());
                notice_array.add(jsonObject.getString("notice").toString());

            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

        adapter = new BaseAdapter2(MainActivity.this, title_array, notice_array);
        list.setAdapter(adapter);

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        // tv.setText("error2");
    }

}
}

 }
