After clicking on any ListActivity item, the first record is always loaded

Good people, I'm having a problem loading a record from a ListActivity .

When I click on any item in ListActivity , my application should open the registration screen so that I can edit some data. So far, okay .. the problem is that it always loads the first item of ListActivity . It does not matter if there are 100 items, after clicking on any one, always the first one is loaded.

If anyone has any idea of what is being done wrong (or is not being done) and can help there ..

If you need any other information or code, just say.

Thank you!

// File ConsClient.java

@Override
protected void onListItemClick(ListView list, View v, int position, long id) {
    super.onListItemClick(list, v, position, id);

    TextView tvCliente = (TextView) findViewById(R.id.tvCodigo);
    TextView tvNome = (TextView) findViewById(R.id.tvNomeLinha);
    TextView tvCnpj = (TextView) findViewById(R.id.tvCNPJLinha);
    TextView tvEmail = (TextView) findViewById(R.id.tvEmail);

    Intent it = new Intent(this, CadCliente.class);  
    Bundle params = new Bundle();

    String codigoCli = tvCliente.getText().toString();
    String nomeCli = tvNome.getText().toString();
    String cnpjCli = tvCnpj.getText().toString();
    String emailCli = tvEmail.getText().toString();


    params.putString("codigoCli", codigoCli);
    params.putString("nomeCli", nomeCli);
    params.putString("cnpjCli", cnpjCli);
    params.putString("emailClie", emailCli);


    it.putExtras(params);
    startActivity(it);
