Wie verwendet man setError() in android TextInputLayout, so dass der jeweilige Fehler angezeigt wird?

Question

Ich habe den Code unten geschrieben. Erstens, ich möchte Fehler von nur einer TextInputLayout Ich arbeite mit. Zweitens, wird der Fehler für das Passwort nicht angezeigt, was kann ich tun, um das zu lösen?

public class DoctorSignUp extends AppCompatActivity implements View.OnClickListener { 

TextView tvSubmit; 
EditText etEmailId, etPassword, etCPassword, etMobile; 
FirebaseAuth firebaseAuth; 
TextInputLayout tilEmailId,tilPassword,tilCPassword,tilMobile; 
ProgressDialog progressDialog; 


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

    //initialize view controls 

    firebaseAuth = FirebaseAuth.getInstance(); 
    progressDialog = new ProgressDialog(this); 

    etEmailId = (EditText) findViewById(R.id.etEmailId); 
    etPassword = (EditText) findViewById(R.id.etPassword); 
    etCPassword = (EditText) findViewById(R.id.etCPassword); 
    etMobile = (EditText) findViewById(R.id.etMobile); 

    tvSubmit = (TextView) findViewById(R.id.tvSubmit); 

    tilEmailId= (TextInputLayout) findViewById(R.id.tilEmailId); 
    tilPassword= (TextInputLayout) findViewById(R.id.tilPassword); 
    tilCPassword= (TextInputLayout) findViewById(R.id.tilCPassword); 
    tilMobile= (TextInputLayout) findViewById(R.id.tilMobile); 

    //event handling 

    tvSubmit.setOnClickListener(this); 


    etEmailId.addTextChangedListener(new MyTextWatcher(DoctorSignUp.this)); 
    etPassword.addTextChangedListener(new MyTextWatcher(DoctorSignUp.this)); 
    etCPassword.addTextChangedListener(new MyTextWatcher(DoctorSignUp.this)); 
    etMobile.addTextChangedListener(new MyTextWatcher(DoctorSignUp.this)); 
} 

@Override 
public void onClick(View v) { 

    registerUser(); 

} 

private void registerUser() { 

    String email = etEmailId.getText().toString(); 
    String password = etPassword.getText().toString(); 


    if (TextUtils.isEmpty(email)) { 
     Toast.makeText(getApplicationContext(), "Please enter email address", Toast.LENGTH_SHORT).show(); 
     return; 
    } 

    if (TextUtils.isEmpty(password)) { 
     Toast.makeText(getApplicationContext(), "Please enter password", Toast.LENGTH_SHORT).show(); 
     return; 
    } 

    progressDialog.setMessage("Registering User,Please wait.."); 
    progressDialog.show(); 

    firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { 
     @Override 
     public void onComplete(@NonNull Task<AuthResult> task) { 
      if (task.isSuccessful()) { 
       Toast.makeText(getApplicationContext(), "Registration Successful", Toast.LENGTH_SHORT).show(); 
      } else 

      { 
       Toast.makeText(getApplicationContext(), "Failed To Register The User", Toast.LENGTH_SHORT).show(); 
      } 
      progressDialog.dismiss(); 
     } 
    }); 
} 

private class MyTextWatcher implements TextWatcher { 
    public MyTextWatcher(Context context) { 
    } 

    @Override 
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

    } 

    @Override 
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

    } 

    @Override 
    public void afterTextChanged(Editable editable) { 

     validateEmail(); 
     validatePasswword(); 
     validateConformPassword(); 
     validateMobile(); 


    } 

    private void validateConformPassword() { 

     String password = etPassword.getText().toString(); 
     String cpassword=etCPassword.getText().toString(); 

     if(!password.equals(cpassword)){ 
      tilCPassword.setError("Please enter the same password again"); 
     } 
     else 
      tilCPassword.setErrorEnabled(false); 


    } 


    private void validateMobile() { 
     String mobile = etMobile.getText().toString(); 

     if(mobile.length()<10) { 
      tilMobile.setError("Enter a valid mobile no."); 
     } 

     else 
      tilMobile.setErrorEnabled(false); 
    } 

    private void validatePasswword() { 

     String password = etPassword.getText().toString(); 

     if (password.length() <6){ 
      tilPassword.setError("Password must be of 6 characters atleast"); 
     } 
     else 
      tilPassword.setErrorEnabled(false); 
    } 

    private void validateEmail() { 

     String email = etEmailId.getText().toString(); 

     if(!email.matches("[a-zA-Z0-9._-]+@[a-z]+.[a-z]+")){ 
      tilEmailId.setError("Please enter valid email id"); 
     } 
     else 
      tilEmailId.setErrorEnabled(false); 
    } 
} 

}

Versuchen Sie, diese Art der Methode übereinstimmen.

public boolean validate() { 
     boolean valid = true; 
     enteredEmailId = mEmail.getText().toString(); 
     enteredPassword = mPassword.getText().toString(); 
     if (enteredEmailId.isEmpty() || !android.util.Patterns.EMAIL_ADDRESS.matcher(enteredEmailId).matches()) { 
      mEmail.setError("Please Enter Valid Email Address"); 
      valid = false; 
     } else { 
      mEmail.setError(null); 
     } 
     if (enteredPassword.isEmpty() || enteredPassword.length() < 4 || enteredPassword.length() > 10) { 
      mPassword.setError("Password should be between 4 to 10 alphanumeric characters"); 
      valid = false; 
     } else { 
      mPassword.setError(null); 
     } 
     return valid; 
    } 
}

versuchen diese

Sie Gesamten Text validieren können, wie Sie nehmen alles in einem

private class MyTextWatcher implements TextWatcher { 
    public MyTextWatcher(Context context) { 
    } 

    @Override 
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

    } 

    @Override 
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

    } 

    @Override 
    public void afterTextChanged(Editable editable) { 



    switch (view.getId()) { 
      case R.id.etEmailId: 


     validateEmail(); 

    break; 

    case R.id.etPassword: 


    validatePasswword(); 

    break; 

    case R.id.etCPassword: 


     validatePasswword(); 
     validateConformPassword(); 

    break; 

    case R.id.etMobile: 


     validateMobile(); 

    break; 






    } 




    } 

Wunsch

die equalsIgnoreCase Gebrauchte Zeichenfolge

private void validateConformPassword() { 

    String password = etPassword.getText().toString(); 
    String cpassword=etCPassword.getText().toString(); 

    if(!password.equalsIgnoreCase(cpassword)){ 
     tilCPassword.setError("Please enter the same password again"); 
    } 
    else 
     tilCPassword.setErrorEnabled(false);
