Android ArrayList, HashMap and Clickable ListView

I am coding a delete screen for the Android W.A.R. app. Get it here at Google Play before I break it.

Meanwhile, in order to list the geotags that can be deleted, I will need a list of geotags with "id" as the key.

So first, I use an Async task to make the HTTP call to my server and select geotags by "id". I will not show that proprietary code here, but I can show the Async's onPostExecute method where the following occurs:

Receive a table with two columns: id and title

Populate a HashMap with the columns named: "id" and "title"

Assign the HashMap values to an ArrayList

Send the ArrayList to a clickable ListView that uses android.R.layout.simple_list_item_2

Convert the ArrayList row back to a HashMap to retrieve "Id".

There must be a more elegant way to do this, but you get what you pay for. I do this for fun and for free.

Just the bare bones...

@Override
protected void onPostExecute(String[][] result)
{
final ArrayList> alist = new ArrayList>();
int size = result.length;
for (int i = 0; i < size; i++) {
  HashMap cols = new HashMap();
  cols.put("id", result[i][0]);
  cols.put("title",result[i][1]);
  alist.add(cols);
}
// release result table
result = null;
//Identify the column names
String[] from = { "id", "title" };
//Send corresponding values to fields in android.R.layout.simple_list_item_2
int[] to = { android.R.id.text1, android.R.id.text2 };
ListView delview = (ListView) findViewById(R.id.list3);
//Set up the adapter to hold the two column table
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), alist,
      android.R.layout.simple_list_item_2, from, to);
delview.setAdapter(adapter);
adapter.notifyDataSetChanged();
//The Click Listener on each row
delview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view, int position1, long id) {
    Map mid = alist.get(position1);
    String sid = mid.get("id");
    Toast.makeText(getBaseContext(), "Clicked on tag Id: "+sid,
    Toast.LENGTH_SHORT).show();
});
return;
}
