creating a menu after a long click event on a list view

Instead of using onItemLongClick you can use

public void onCreateContextMenu(final ContextMenu menu, 
                    final View v, final ContextMenuInfo menuInfo) {
 ...
}

where you setup the options for edit and delete or whatever you need to.

The actions for the item selected from the context menu can be processed in

public boolean onContextItemSelected(final MenuItem item)

For more information on context menu see here.

Edit The second link is broken as it was quite old. But I guess you can refer one of the other highly voted answer to see all the steps involved,

First you need to register your context menu on list view.

lv = (ListView) findViewById(R.id.list_view);
registerForContextMenu(lv);

Then, just override activity methods.

/**
 * MENU
 */

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
      super.onCreateContextMenu(menu, v, menuInfo);
      if (v.getId()==R.id.list_view) {
          MenuInflater inflater = getMenuInflater();
          inflater.inflate(R.menu.menu_list, menu);
      }
}

@Override
public boolean onContextItemSelected(MenuItem item) {
      AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
      switch(item.getItemId()) {
         case R.id.add:
         // add stuff here
            return true;
          case R.id.edit:
            // edit stuff here
                return true;
          case R.id.delete:
        // remove stuff here
                return true;
          default:
                return super.onContextItemSelected(item);
      }
}

Here is an example of menu_list.xml file (you have to put the file in the res/menu folder).

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">

       <item android:id="@+id/add"
              android:icon="@android:drawable/ic_menu_add"
              android:title="@string/menu_add" />

      <item android:id="@+id/edit"
              android:icon="@android:drawable/ic_menu_edit"
              android:title="@string/menu_edit" />

       <item android:id="@+id/delete"
            android:icon="@android:drawable/my_icon_delete"
             android:title="@string/menu_delete" />

</menu>

Hope it will help.
