On long click delete item

I have ListView which is saving all data to database. For adding i have simple button and textBox which adds to database, and show to listView. Now i want thath on long item click (hold on item) will delete the selected item from list. How is possible to do thath (actualy what method to call for long click).

Here is current code:

import java.util.List;
import java.util.Random;

import android.app.ListActivity;
import android.os.Bundle;
import android.text.Editable;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;

public class Announce extends ListActivity{
    private CommentsDataSource datasource;
    EditText edit;
    ListView list;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.announce);

        datasource = new CommentsDataSource(this);
        datasource.open();

        List<Comment> values = datasource.getAllComments();

        ArrayAdapter<Comment> adapter = new ArrayAdapter<Comment>(this,
                android.R.layout.simple_list_item_1, values);
        setListAdapter(adapter);
    }


    public void onClick(View view) {
        @SuppressWarnings("unchecked")
        ArrayAdapter<Comment> adapter = (ArrayAdapter<Comment>) getListAdapter();
        Comment comment = null;
        switch (view.getId()) {
        case R.id.add:
            edit = (EditText)findViewById(R.id.editTxt);
            Editable txt=(Editable)edit.getText();
            String input = txt.toString();          
            comment = datasource.createComment(input);
            adapter.add(comment);
            break;  
        }
        adapter.notifyDataSetChanged();
    }



    @Override
    protected void onResume() {
        datasource.open();
        super.onResume();
    }

    @Override
    protected void onPause() {
        datasource.close();
        super.onPause();
    }

}
