Я пытаюсь использовать EditText из Material Design (https://material.io/develop/android/components/text-fields/) и получаю исключение во время выполнения.

Я хочу решить эту проблему

EditText Проблема: Когда я пытаюсь открыть приложение с обычным EditText на мониторе и приложение Cra sh [закрыто]

Это часть журнала выполнения:

Также та же ошибка 

You are casting TextInputLayout into EditText which is not possible, instead of this please try to cast TextInputEditText into EditText it will resolve your problem.

мой java код 

public
class SignInActivity extends AppCompatActivity {

    TextInputEditText edtName, edtphone,edtpassword;
    Button signinbtn1,cancel1;

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

    ////////////////Text Input///////////////////
        edtName =(TextInputEditText)findViewById(R.id.edtName);

        edtpassword = (TextInputEditText)findViewById(R.id.edtpassword);
        edtphone = (TextInputEditText)findViewById(R.id.edtphone);

Вы должны дать идентификатор TextInputEditText, как этот, вместо TextInputLayout. Это решит вашу проблему:
