implement AsyncTask in Fragment android

There is easy step to crate asyntask within fragment

in your fragment place code on activityCreateview

new MyAsyncTask(getActivity(), mListView).execute("");

getActivity() is method to communicate with fragment and activity

in asynstak on post

context.mListView.setArrayAdapter(...........)

here is

public class SalesFragment extends Fragment {
GridView gridView;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View gv = inflater.inflate(R.layout.hot_sales, null);
       gridView = (GridView) gv.findViewById(R.id.grid_view);
        bindGridView()
        return gv;
        //return super.onCreateView(inflater, container, savedInstanceState);
    }

public void bindGridview()
{

   new MyAsyncTask(getActivity(), gridView).execute("");
}

class MyAsyncTask extends AsyncTask<String, String, String>
{
    GridView mGridView;
    Activity mContex;
   public  MyAsyncTask(Activity contex,GridView gview)
    {
     this.mGridView=gview;
     this.mContex=contex;
    }

   protected String doInBackground(String... params)
    {

       //fetch data
    }

   @Override
    protected void onPostExecute(String result) {
      {   

        for(Sales sales : this.response.sales){
            HashMap<String, String> hm = new HashMap<String,String>();

            if (sales.getCategories1().contains("12")){
                //hm.put("sale_title", "" + sales.getShort_title());
                for(Shop shop : this.response.shops){
                    String image_file = new String(        Environment.getExternalStorageDirectory().getAbsolutePath()
                            + "/images/" + shop.getImage());
                    if(shop.getId().equals(sales.getShop_id())){
                        hm.put("shop_image", image_file );
                        System.out.println(shop_image);
                    }
                }
            }
        }
               if(hm.size()>0)
              mcontext.mGridView.setAdapter(new ImageAdapter(mContext),hm);
      }

before fetching data make it model like

public class ImageModel
    {
        String title;
        String img;
    }


ArrayList<ImageModel> arrayList=new ArrayList<ImageModel>();

fill array list with required data
then

mcontext.mGridView.setAdapter(new ImageAdapter(mContext),hm,arrayList);

//in image adapter

public class ImageAdapter extends ArrayAdapter<String> {

public ImageAdapter(Context context, HashMap<String, String> hm,ArrayList<ImageModel> images ) 
        {
            super(context, R.layout.activity_t);

        }
//--code
   }

use hash map in adapter and assign images with position
set data and fetch value from model
