Componentes sobrepostos!!

Olá pessoal, alguém poderia me ajudar? Os nomes dos alunos estão sobrepostos no emulador. Segue o código:

public class MainActivity extends Activity {

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    List<String> alunos = new ArrayList<>(Arrays.asList("Matheus eli","Catarina", "Sofia"));

    TextView primeiroaluno = findViewById(R.id.textView);
    TextView segundoaluno = findViewById(R.id.textView2);
    TextView terceiroaluno = findViewById(R.id.textView3);

    primeiroaluno.setText(alunos.get(0));
    segundoaluno.setText(alunos.get(1));
    terceiroaluno.setText(alunos.get(2));
}

}

activity_main.xml:
