    public class MyListFragment1 extends ListFragment {

ImageView back;
String url = Main.url;
String Qrimage;
Bitmap bmp;
ListView  list ;

AppetiserFragment adapter;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    return inflater.inflate(R.layout.applistviewfragment, container, false);

}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    // back=(ImageView)findViewById(R.id.backfoodmenu);
    /*
     * back.setOnClickListener(new OnClickListener() {
     * 
     * public void onClick(View v) { // TODO Auto-generated method stub
     * Intent intent=new Intent(getApplicationContext(),FoodMenu.class);
     * intent.putExtra("url", url); startActivity(intent); } });
     */
    ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();

    InputStream is = null;
    String result = "";
    JSONObject jArray = null;
    try {
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url + "test.php3");
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
    } catch (Exception e) {
        // TODO: handle exception
        Log.e("Log", "Error in Connection" + e.toString());

        // Intent intent = new Intent(ViewQRCode.this, PimCarder.class);

        // startActivity(intent);

    }
    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        result = sb.toString();
        jArray = new JSONObject(result);

        JSONArray json = jArray.getJSONArray("appetiser");

        Context context = null;
        context = this.getActivity().getApplicationContext();
                   //(Here i want give lisid from xml)
                     list=(Listview)findViewById(R.id.list);//i type here it shows an error
        adapter = new AppetiserFragment(context, json);

        context = getActivity().getApplicationContext();
        list.setAdapter(adapter);

    } catch (Exception e) {
        // TODO: handle exception
        Log.e("log", "Error in Passing data" + e.toString());
    }
}

}

    return view;
}


static class ViewHolder {

    protected TextView text, price, desc, appitemnum;
    protected ImageView image;

}

 }

i can able to print json data in base adpater class . Now i want pass json data in to text,image. i thought getview method is not calling . please help me

Answer 1

You can also user ListActivity instead of ListFragment. It will behave like normal activity and you can find all the list related methods easily.

like this..,

 public class MainActivity extends ListActivity {
oncreate() {
** code
ListView list = getListView();

 **code
}
}
