made a search on my list however it needs me to click enter to complete the search and show the results. I would like the result to come automatically when typing. Thank you. 
My code:
........ 
public class ListClientes extends AppCompatActivity implements AdapterView.OnItemLongClickListener, AdapterView.OnItemClickListener {
ListView lista;
ArrayList<Cliente> clientes;
EditText search;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.list_clientes);
    lista = (ListView) findViewById(R.id.listview);
    search = (EditText) findViewById(R.id.search);
    lista.setOnItemLongClickListener(this);
    lista.setOnItemClickListener(this);
    atualizar(null);
    search.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            atualizar(null);
            return false;
        }
    });
}
public void atualizar(View view) {
    ClienteDao cliDao = new ClienteDao();
    clientes = cliDao.getListagem(" where nome like '" + search.getText().toString() + "%'");
    lista.setAdapter(new ClienteAdapter(getBaseContext(), clientes));
  } 
  ........ 
maybe it doesn’t work because cell phones have no buttons, try to use the event
