Android ListView Dynamic Load List entry implementation code _android

Recently a dynamic Loading ListView class table items, sharing out everyone learn to learn, talk about this example of the implementation process, first of all to limit the load of the list item data for 10 data, when the drag ListView scroll to the last data when loading 10, and displays the load prompt below the listview.

Here is my Java source code:

private void Showcontent () {ListView = (ListView) Findviewbyid (R.id.journals_list_one); 
  LoadData (); 
 
  adapter = new Mylistadapter (this, data); 
  Footerview = View.inflate (testlayout.this, R.layout.journal_listitem_loading_bar, NULL); 
 
  Listview.addfooterview (Footerview, NULL, TRUE); 
  Listview.setadapter (adapter); 
 Listview.setonscrolllistener (listener); Private Abslistview.onscrolllistener listener = new Abslistview.onscrolllistener () {@Override public void ONSC 
    Rollstatechanged (abslistview view, int scrollstate) {if (view.getlastvisibleposition () = = View.getcount ()-1) { 
    LoadData (); 
   Adapter.notifydatasetchanged (); @Override public void Onscroll (Abslistview view, int firstvisibleitem, int visibleitemcount, int total 
 
 ItemCount) {}};  
    /** * Construct list data/private void LoadData () {if (Data.size () <=) {for (int i = 0; i < i++) { map<string, string> map = new HASHMAp<string, string> (); 
    Map.put ("title", GetString (R.string.title)); 
    Map.put ("desc", GetString (r.string.content)); 
   Data.add (map); 
  } else {Listview.removefooterview (Footerview);  } 
 }

Implementation of this function is mainly to add ListView Onscrolllistener listening, to determine whether the list items to the most one, if the last one to load data. The load effect when loading data is that the Listview.addfooterview () method implement this method must be useful before listview.setadapter (). When all the data loading is complete, call Listview.removefooterview to remove Footerview.
