How To Implement A Proper Scroll In List View To Implement Pagination On Fragment Activity?

I am building an application like techcrunch. I am fetching data from server in JSON format and displaying the data in list view like article title,author name and image. I have ap

Solution 1:

You can try this (I added a line to set the new list position in the last line of onStart())

With this line you can set the new position_

listView.setSelectionFromTop(newPosition, 0); With the first parameter you set the position, and with the second you set the distnace from the top of the list

@OverridepublicvoidonStart(){
super.onStart();
// calling adapter changes here, just// to avoid getactivity()null// increment current page
current_page += 1;

// Next page requestURL = "http:url&page=" + current_page;
//adapter = new CustomListAdapter(this, movieList);// changing action bar color//getActivity().getActionBar().setBackground(//new ColorDrawable(Color.parseColor("#1b1b1b")));// Creating volley request objJsonArrayRequest movieReq = newJsonArrayRequest(URL,
        newResponse.Listener<JSONArray>() {
            @OverridepublicvoidonResponse(JSONArray response) {
                Log.d(TAG, response.toString());
                hidePDialog();

                // Parsing jsonfor (int i = 0; i < response.length(); i++) {
                    try {

                        JSONObject obj = response.getJSONObject(i);
                        Movie movie = newMovie();
                        movie.setDate(obj.getString("date"));
                        movie.setId(obj.getString("id"));

                        movieList.add(movie);
                        int currentPosition = listView.getFirstVisiblePosition();

                        adapter = newCustomListAdapter(getActivity(), movieList);
                        adapter.notifyDataSetChanged();

                        listView.setAdapter(adapter);
                        listView.setSelectionFromTop(currentPosition + 1, 0);
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }                       
            }
        },newResponse.ErrorListener() {
            @OverridepublicvoidonErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());
                newAlertDialog.Builder(getActivity())
                .setTitle("No Connectivity ")
                .setMessage("Please check your internet connectivity!")
                .setPositiveButton(android.R.string.yes, newDialogInterface.OnClickListener() {
                    publicvoidonClick(DialogInterface dialog, int which) { 
                        // continue with delete
                    }
                 })
                //.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {//public void onClick(DialogInterface dialog, int which) { // do nothing//}//})
                .setIcon(android.R.drawable.ic_dialog_alert)
                 .show();
                hidePDialog();

            }
        });
AppController.getInstance().addToRequestQueue(movieReq);    
listView.setAdapter(adapter);
//Set the new position
listView.setSelectionFromTop(currentPosition  + 1, 0);
 }
