我尝试使用电子邮件和密码在Firebase控制台中创建用户，但它无法显示错误。
实际上，我们可以通过转到仪表板并单击add user来添加控制台中的用户，但我希望自动完成此过程。
这里是完整的代码：

用于创建用户的代码是：
but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
user_id= email.getText().toString();
pass= password.getText().toString();
Firebase ref = new Firebase("https://final-6b828.firebaseio.com/auth");
ref.createUser(user_id, pass, new Firebase.ValueResultHandler<Map<String, Object>>() {
@Override
public void onSuccess(Map<String, Object> result) {
System.out.println("Successfully created user account with uid: " + result.get("uid"));
String a= result.get("uid").toString();
Log.i("Success",user_id);
Log.i("Success",pass);
Toast.makeText(getApplicationContext(), "Pass",
Toast.LENGTH_LONG).show();
}
@Override
public void onError(FirebaseError firebaseError) {
// there was an error
System.out.println("Failed to create user account : ");
Log.i("Failed","a");
Toast.makeText(getApplicationContext(), "Failed",
Toast.LENGTH_LONG).show();
}
});
}
});

创建用户的正确代码是..
but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
user_id= email.getText().toString();
pass= password.getText().toString();
createAccount(user_id,pass);
}
});
private void createAccount(String email, String password) {
Log.d(TAG, "createAccount:" + email);
if (!validateForm()) {
return;
}
// showProgressDialog();
// [START create_user_with_email]
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Toast.makeText(SignInActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// [START_EXCLUDE]
//hideProgressDialog();
// [END_EXCLUDE]
}
});
// [END create_user_with_email]
}
private boolean validateForm() {
boolean valid = true;
String emails = email.getText().toString();
if (TextUtils.isEmpty(emails)) {
email.setError("Required.");
valid = false;
} else {
email.setError(null);
}
String passwords = password.getText().toString();
if (TextUtils.isEmpty(passwords)) {
password.setError("Required.");
valid = false;
} else {
password.setError(null);
}
return valid;
}
