I have a listview where people name and when I click on a person I use the adapter.getitem(position) that takes the person's name, however, I needed to get the id of the person and not the name. Does anyone know how I can do this? Briefly I need to bring 2 database data, the name and the id, however only present the name in the listView and get the id when clicking. there are similar names, so I need the id.

obs: I'm currently doing something I do not know if it's gambiarra or it's smart. list the names and when I click on the name use the option to get the id. It's working right now but it's not good practice.

When you query to get the names and popular the listview, create a ArrayList and populate it with the ids of the names.

In the OnClick event of the listview, you can return the id of the name clicked like this:

seuListView.setOnItemClickListener(new OnItemClickListener() {

  @Override
  public void onItemClick(AdapterView<?> parent, View view,
    int position, long id) {

   //retornando o id do nome clicado a partir do ArrayList já populado
   String id= arrayDeId.get(position);

  }
});

Hello

You can create a CustomAdapter for your ListView using a BaseAdapter. With it created, you can add each Person entity and in the listview click retrieve only the person ID. Here has an example of how to create a custom with BaseAdapter.

I hope to have helped, any questions leave a comment.
