Dynamic add Lsitview code instance in Android development

This is very simple to explain don't forget adapter.notifydatasetchanged ();

Wake up, in fact, this wake-up call is used under the button or in other controls down use if it's under the GetView, it's not necessary.

Java code:

public class Dynamiclistitems extends Listactivity {

private static final String Item_key = "KEY";

arraylist

Private Simpleadapter adapter;

Private EditText newvalue;

@Override

public void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (r.layout.dynamic_list);

NewValue = (edittext) Findviewbyid (R.id.new_value_field);

Setlistadapter (this, list, R.layout.row, new string[] {Item_key}, new int[] {r.id.list_value}) (new Simpleadapter);

((ImageButton) Findviewbyid (R.id.button)). Setonclicklistener (Getbtnclicklistener ());

}

Private Onclicklistener Getbtnclicklistener () {

return new Onclicklistener () {

public void OnClick (view view) {

try {

hashmap<string, string> item = new hashmap<string, string> ();

Item.put (Item_key, Newvalue.gettext (). toString ());

List.add (item);

Adapter.notifydatasetchanged ();

catch (NullPointerException e) {

LOG.I ("[Dynamic Items]", "tried to add null value");

}

}

};

}

}
