Append or prepend listView

Question

How is best method to append or prepend ListView ?

A starting point is this tutorial.

http://www.androidbegin.com/tutorial/android-parse-com-listview-load-more-using-onscrolllistener-tutorial/

    adapter = new ListViewAdapter(MainActivity.this, numberlist);

// Binds the Adapter to the ListView listview.setAdapter(adapter);

But i think this method is reloading the list.

There are other ways of implementing or it would be best?

then you can add to list using `numberlist.add(yourObjects)` then call `adapter.notiftDataSetChanged()` — Mohammad Ersan, Jan 19 '15 at 00:11

i think thats the best way to pupulate listview and setAdapter is not for reloading the list that is to Sets the data behind this ListView

notiftDataSetChanged() method is to reload the list if you update the list.

one more thing if you want to use custome layout for your list then what your are doing is the best way but if you want to use default layout that android provides then

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
          android.R.layout.simple_list_item_1, android.R.id.text1, values);  
      // Assign adapter to ListView
        listView.setAdapter(adapter);

I have a list of 100 results. In this list want to look for a method to add one or more elements at the beginning or end of the list. – Valy Dvweb Jan 18 '15 at 17:50
How may refer to certain positions ? – Valy Dvweb Jan 18 '15 at 17:51
if you want to do that then update your list and the call adapter.notifyDataSetCanged(); and it will update your list – Moubeen Farooq Khan Jan 18 '15 at 17:52

OK ... so the position is defined by the ArrayList that has to be updated? – Valy Dvweb Jan 18 '15 at 18:04
my pleasure ... if your are satisfied w ith the answer kindly accept it – Moubeen Farooq Khan Jan 18 '15 at 18:07
Note that ArrayAdapter has 'add' and 'addAll' methods similar to those of List, and allow for adding items dynamically to the ListView, without having to maintain a List yourself. You will still have to call notifyDataSetChanged afterwards. – 2Dee Jan 20 '15 at 12:36
