英文:
Firebase Custom Userfield crash - Android Studio
问题
以下是已翻译好的代码部分：
public class SignUp extends AppCompatActivity {
//变量
private EditText regName, regNpm, regUsername, regEmail, regPassword, regCoPassword;
private Button regBtn, regToLoginBtn;
ProgressBar signUp_progress;
private DatabaseReference databaseReference;
private FirebaseDatabase firebaseDatabase;
private FirebaseAuth mAuth;
String fullname, username, email, npm, password, co_password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_sign_up);
signUp_progress = findViewById(R.id.signUp_progress);
regName = findViewById(R.id.reg_name);
regNpm = findViewById(R.id.reg_npm);
regUsername = findViewById(R.id.reg_username);
regEmail = findViewById(R.id.reg_email);
regPassword = findViewById(R.id.reg_password);
regCoPassword = findViewById(R.id.reg_CoPassword);
regBtn = findViewById(R.id.reg_btn);
regToLoginBtn = findViewById(R.id.reg_login_btn);
mAuth = FirebaseAuth.getInstance();
firebaseDatabase = FirebaseDatabase.getInstance();
databaseReference = firebaseDatabase.getReference("UserData");
regToLoginBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Login.class);
startActivity(intent);
}
});
regBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!validateFullname() | !validateUsername() | !validateEmail() | !validatePassword() | !validateNpm()) {
return;
}
if (regPassword.equals(regCoPassword)) {
signUp_progress.setVisibility(View.VISIBLE);
mAuth.createUserWithEmailAndPassword(email, String.valueOf(regPassword)).addOnCompleteListener
(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
UserData data = new UserData(fullname, username, email, npm);
FirebaseDatabase.getInstance().getReference("UserData")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid()).setValue(data).
addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
signUp_progress.setVisibility(View.GONE);
Toast.makeText(SignUp.this, "Successful Registered", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(SignUp.this, MenuActivity.class);
startActivity(intent);
finish();
}
});
} else {
signUp_progress.setVisibility(View.GONE);
Toast.makeText(SignUp.this, "Check Email id or Password", Toast.LENGTH_SHORT).show();
}
}
});
} else {
Toast.makeText(SignUp.this, "Password didn't match", Toast.LENGTH_SHORT).show();
}
}
});
}
// 省略其他部分...
}
public class Login extends AppCompatActivity {
Button callSignUp, loginBtn;
ImageView image;
TextView logoText, sloganText;
TextInputLayout username, password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_login);
callSignUp = findViewById(R.id.signup_screen);
image = findViewById(R.id.logo_image);
logoText = findViewById(R.id.logo_text);
sloganText = findViewById(R.id.slogan_text);
username = findViewById(R.id.username);
password = findViewById(R.id.password);
loginBtn = findViewById(R.id.login_btn);
callSignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Login.this,SignUp.class);
Pair[] pairs = new Pair[7];
pairs[0] = new Pair<View,String>(image,"logo_image");
pairs[1] = new Pair<View,String>(logoText,"logo_text");
pairs[2] = new Pair<View,String>(sloganText,"logo_desc");
pairs[3] = new Pair<View,String>(username,"uname_tran");
pairs[4] = new Pair<View,String>(password,"password_tran");
pairs[5] = new Pair<View,String>(loginBtn,"button_tran");
pairs[6] = new Pair<View,String>(callSignUp,"login_signup_tran");
ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(Login.this,pairs);
startActivity(intent, options.toBundle());
}
});
}
}
以上是代码的翻译部分，包括SignUp.java和Login.java中的关键部分。至于出现的错误日志，是因为在SignUp.java中的布局文件中使用了com.google.android.material.textfield.TextInputLayout，但在代码中使用findViewById查找对应的组件时，使用了EditText而不是TextInputLayout。需要修改相关代码以正确处理布局中的组件。
英文:
As the title said. I want to make a custom authentication with username on Register form. All code was good and there is no error. But when I'm trying to run the app, It's force close when After I click the Registration button from the Login page. So this is the list code in SignUp.java
public class SignUp extends AppCompatActivity {
//Variabel
private EditText regName, regNpm, regUsername, regEmail, regPassword, regCoPassword;
private Button regBtn, regToLoginBtn;
ProgressBar signUp_progress;
private DatabaseReference databaseReference;

private FirebaseAuth mAuth;
String fullname, username, email, npm, password, co_password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Line dibawah untuk menghilangkan status bar dari screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_sign_up);
//Hooks ke semua elemen xml di activity_sign_up.xml

regToLoginBtn = findViewById(R.id.reg_login_btn);
// Get Firebase auth instance
mAuth = FirebaseAuth.getInstance();

regToLoginBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Login.class);
startActivity(intent);
}
});
// handle user SignUp button
regBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!validateFullname() | !validateUsername() | !validateEmail() | !validatePassword() | !validateNpm()) {
return;
}
if (regPassword.equals(regCoPassword)) {
// progressbar VISIBLE
signUp_progress.setVisibility(View.VISIBLE);
mAuth.createUserWithEmailAndPassword(email, String.valueOf(regPassword)).addOnCompleteListener
(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
UserData data = new UserData(fullname, username, email, npm);
FirebaseDatabase.getInstance().getReference("UserData")

addOnCompleteListener(new OnCompleteListener<Void>() {

}
});
} else {

}
}
});
} else {
Toast.makeText(SignUp.this, "Password didn't match", Toast.LENGTH_SHORT).show();
}
}
});
}
private boolean validateFullname() {
fullname = regName.getText().toString().trim();
if (TextUtils.isEmpty(fullname)) {

}

}
}
// if the user already logged in then it will automatically send on Dashboard/MainActivity activity.
@Override
public void onStart() {
super.onStart();
if (FirebaseAuth.getInstance().getCurrentUser() != null) {
Intent intent = new Intent(SignUp.this, MenuActivity.class);
startActivity(intent);
}
}
}
And this is the listing code from Login.java
public class Login extends AppCompatActivity {
//Variabel
Button callSignUp, loginBtn;
ImageView image;
TextView logoText, sloganText;
TextInputLayout username, password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Line dibawah untuk menghilangkan status bar dari screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_login);
//Hooks
callSignUp = findViewById(R.id.signup_screen);
image = findViewById(R.id.logo_image);
logoText = findViewById(R.id.logo_text);
sloganText = findViewById(R.id.slogan_text);
username = findViewById(R.id.username);
password = findViewById(R.id.password);
loginBtn = findViewById(R.id.login_btn);
callSignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Login.this,SignUp.class);
Pair[] pairs = new Pair[7];
pairs [0] = new Pair<View,String>(image,"logo_image");
pairs [1] = new Pair<View,String>(logoText,"logo_text");
pairs [2] = new Pair<View,String>(sloganText,"logo_desc");
pairs [3] = new Pair<View,String>(username,"uname_tran");
pairs [4] = new Pair<View,String>(password,"password_tran");
pairs [5] = new Pair<View,String>(loginBtn,"button_tran");
pairs [6] = new Pair<View,String>(callSignUp,"login_signup_tran");
ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(Login.this,pairs);
startActivity(intent, options.toBundle());
}
});
}
}
And then there's logcat

答案1
得分: 1
它报告 ClassCastException，因为您将 TextInputLayout 误当作 EditText 处理。为包装的 editText 设置单独的 id，并在该视图上调用 getText()，而不是调用 TextInputLayout 上的方法。
英文:
it says ClassCastException because you treat TextInputLayout as EditText. Set a separate id for for the wrapped editText and call getText() on that view instead.
