Android implementing LISTVIEW with context menu trying to add "Favorites"

Hello I am a beginner in android programming. I have this recipe app with sqlite database. I am already done making the context menu with add to favorites on it. My problem is that I do not know how I to put the selected recipe to my dbase table named "favorites".. based on the TOAST. I am already getting the position of the listview.

@SuppressLint("ShowToast")
@Override
public boolean onContextItemSelected(MenuItem item) {
  // TODO Auto-generated method stub
  AdapterContextMenuInfo info =(AdapterContextMenuInfo)item.getMenuInfo();
  itemPos = info.position;
  ContentValues values = new ContentValues();
  switch (item.getItemId()) {
    case R.id.addtofavorites:
      Toast.makeText(getBaseContext(), "Added to Favorites"+itemPos, Toast.LENGTH_SHORT).show();
      return true;
    default:
      return super.onContextItemSelected(item);
  }
}
