How do I dynamically add items to a ListView in Android?

Question

I am using custom adapter to display a ListView.

It is working fine.

But i need to add three items to the ListView. How do I add them and have them display?

I tried notifydatasetchanged() method that is not working.

You have to add items to your list using list.add(...) then you tell the adapter with adapter.notifyDataSetChanged().

For adding item into the listview you must use the List/ArrayList object. Using this you can perform add/edit/delete operation on listview item data and this list set into your adapter to get the data from list/arraylist and set into list item.

Ok now suppose I have listview and want to add new item just add item into the list/arraylist object and notify to the adapter like this

List<String> myList = new ArrayList<String>();
ArrayAdapter<String> adapter;

oncreate(){
   // initi listview, adapter and set the myList object into adapter object and then set the adapter into listview


}

// on button click from somewhere
public void onClick(View view){
    myList.add("hello friends");// you can add your data here into list object
    adapter.notifyDataSetChanged();
}
