try like this:

 //used for populate the listView
 private void populateListView(HashMap datas){
    if(mRecipeAdapter ==null){
       String[] keys = {KEY_TITLE};
       int[] ids = {R.id.list_recipe_title};
       mRecipeAdapter = new ExtendedSimpleAdapter(getContext(), datas, R.layout.itemlistrow, keys, ids);
       listView.setAdapter(mRecipeAdapter);
    }else
    {
      mRecipeAdapter.notifyDataSetChanged();
    }
 }
//create ListView Data::: i have removed your five last line, and repleced them by return mRecipePostData 
private ArrayList> getRecipeData() throws JSONException {
        JSONArray jsonPosts = mRecipeData.getJSONArray("posts");
        mRecipePostData = new ArrayList>();
        for (int i = 0; i < jsonPosts.length(); i++){
            JSONObject post = jsonPosts.getJSONObject(i);
            String title = post.getString(KEY_TITLE);
            title = Html.fromHtml(title).toString();
            String author = post.getJSONObject(KEY_AUTHOR).getString("name");
            author = Html.fromHtml(author).toString();
            String imgUrl = post.getJSONObject(KEY_IMG_URL).getJSONObject("full").getString("url");
            String recipeContent = post.getString(KEY_CONTENT);
            recipeContent = Html.fromHtml(recipeContent).toString();
            String recipeUrl = post.getString(KEY_RECIPE_URL);

            HashMap singleRecipePost = new HashMap<>();
            singleRecipePost.put(KEY_TITLE, title);
            singleRecipePost.put(KEY_AUTHOR, author);
            singleRecipePost.put(KEY_IMG_URL, imgUrl);
            singleRecipePost.put(KEY_CONTENT, recipeContent);
            singleRecipePost.put(KEY_RECIPE_URL, recipeUrl);

            mRecipePostData.add(singleRecipePost);
        }
       return mRecipePostData;
    } 

//after getData, i am populating ListView
private void handleRecipeData() {
        mProgressBar.setVisibility(View.INVISIBLE);
        if(mRecipeData == null){
            handleErrors();

        }else {
            try {
                HashMap datas=getRecipeData();
                populateListView(datas);

            } catch (JSONException e) {
                Log.e(LOG_TAG,"Exception Caught: ",e);
            }
        }
    }
