i need to populate a list view with json data and also give a pagination feature to that screen. the listView should show 5 datas at a time and on clicking the pagination button the listview should show the next 5 datas.

here is the code that i have used

try {
                    Toast.makeText(getApplicationContext(), response, Toast.LENGTH_SHORT).show();
                    JSONObject obj = new JSONObject(response);
                    JSONArray jsonArray = obj.getJSONArray("contacts");
                    int length = jsonArray.length();
                    if (length != 0)
                    {
                        for (int i = 0; i < length; i++)
                        {
                            JSONObject user = jsonArray.getJSONObject(i);
                            for (int l = 1; l <= 5; l++)
                            {
                                preference_array.add(user.getString("id").toString());
                            }
                        }
                    }
                        int rem = preference_array.size() % rowSize;
                        if (rem > 0) {
                            for (int k = 0; k < rowSize - rem; k++) {
                                preference_array.add("");
                            }

                            addItem(0);

                            int size = preference_array.size() / rowSize;

                            for (int j = 0; j < size; j++) {
                                final int k;
                                k = j;
                                final Button btnPage = new Button(MainActivity.this);
                                LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(120, ViewGroup.LayoutParams.WRAP_CONTENT);
                                lp.setMargins(5, 5, 5, 5);
                                btnPage.setTextColor(Color.WHITE);
                                btnPage.setTextSize(20.0f);
                                btnPage.setId(j);
                                btnPage.setText(String.valueOf(j + 1));
                                mLinearScroll.addView(btnPage, lp);
                                btnPage.setOnClickListener(new View.OnClickListener() {
                                    @Override
                                    public void onClick(View v) {
                                        // TODO Auto-generated method stub
                                        /**
                                         * add arraylist item into list
                                         */
                                        addItem(k);
                                    }
                                });
                            }
                        }
                       
                        display();
                 
                } 

private void addItem(int i) {
        // TODO Auto-generated method stub
        preference_array_temp.clear();
        i = i * rowSize;

        /**
         * fill temp array list to set on page change
         */
        for (int j = 0; j < rowSize; j++) {
            preference_array_temp.add(j, preference_array.get(i));
            i = i + 1;
        }

        // set view
        display();
    }

    private void display() {
        adapter = new CustomBaseAdapter(MainActivity.this, preference_array);
        fav.setAdapter(adapter);
    }

i am able to populate the listview and display the pagination button. but the listview repeats the all the data 5 times and loads all 13*5 times data in the listView.

i need to be able to click the 2nd pagination button and show the next 5 datas. where could i have gone wrong. please give guidance.
