我的代码运行良好，但今天运行后出现了下一个错误：
androidx.appcompat.widget.AppCompatButton无法转换为com.google.android.material.textfield.TextInputLayout
第92行的错误：verify_code = findViewById(R.id.verify_code);
当活动开始时，应用程序中断，我得到以下错误
java代码
public class PhoneLoginActivity extends AppCompatActivity {
private EditText InputUserPhoneNumber, InputUserVerificationCode;
private Button SendVerificationCodeButton, VerifyButton;
private long backPressedTime;
private Toast backToast;
ProgressDialog progressDialog;
private PhoneAuthProvider.OnVerificationStateChangedCallbacks callbacks;

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
mStorageRef = FirebaseStorage.getInstance().getReference();
mFirebaseDatabase = FirebaseDatabase.getInstance();
dbRef = mFirebaseDatabase.getReference("Guest");
InputUserPhoneNumber = (EditText) findViewById(R.id.phone_text);
InputUserVerificationCode = (EditText) findViewById(R.id.pwd_text);
SendVerificationCodeButton = (Button) findViewById(R.id.login_btn);
VerifyButton = (Button) findViewById(R.id.verify_button);
loadingBar = new ProgressDialog(this);
phone_num = findViewById(R.id.phone_number);
verify_code = findViewById(R.id.verify_code);
phone_number = InputUserPhoneNumber.getText().toString();

我认为，代码中没有错误。你能从设备上卸载该应用程序吗？重建并重新安装该应用程序。
