List<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();HashMap<String, String> map = new HashMap<String, String>();map.put("tv", "tv");list.add(map);list.add(map);list.add(map);list.add(map);list.add(map);list.add(map);

<span style="white-space:pre"></span>SimpleAdapter sa = new SimpleAdapter(this, list, R.layout.item_lv,<span style="white-space:pre"></span>new String[] { "tv" }, new int[] { R.id.tv });

<span style="white-space:pre"></span>lv.setAdapter(sa);

5. Set the item Click Event

Lv. setOnItemClickListener (new OnItemClickListener () {@ Overridepublic void onItemClick (AdapterView <?> Arg0, View arg1, int position, long id) {// position if the first of headview position = 0 is headviewToast. makeText (MainActivity. this, "position:" + position, Toast. LENGTH_SHORT ). show (); // id: If headview or footview exists, the IDs of these two views are-1if (id =-1) {Toast. makeText (MainActivity. this, "head:" + id, Toast. LENGTH_SHORT ). show ();} else {Toast. makeText (MainActivity. this, "id:" + id, Toast. LENGTH_SHORT ). show ();}}});
