Question

我正在加载栏上显示“请稍等，我们正在检查凭据”，正在创建一个电子商务应用，卡在创建帐户上。在Firebase中创建实时数据库时。

我试图创建一个实时数据库

public class register extends AppCompatActivity {

    EditText username, pass, phonenumber ;
    Button createaccount;
    ProgressDialog loadingbar;


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

        username = findViewById(R.id.username);
        pass = findViewById(R.id.reg_password);
        phonenumber = findViewById(R.id.reg_phone_number);
        createaccount=findViewById(R.id.create_account);
        loadingbar=new ProgressDialog(this);


        createaccount.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                CreateAccount();

            }
        });
}

    private void CreateAccount() {
        String name = username.getText().toString();
        String phone = phonenumber.getText().toString();
        String password = pass.getText().toString();

        if(TextUtils.isEmpty(name))
        {
            Toast.makeText(register.this, "Please enter name...", Toast.LENGTH_SHORT).show();
        }

        else if (TextUtils.isEmpty(phone))

        {
            Toast.makeText(register.this, "Please enter phone...", Toast.LENGTH_SHORT).show();
        }

        else if (TextUtils.isEmpty(password))

        {
            Toast.makeText(register.this, "Please enter password...", Toast.LENGTH_SHORT).show();
        }

        else
        {
            loadingbar.setTitle("Create Account");
            loadingbar.setMessage("Please wait, while we are checking the credentials..");
            loadingbar.setCanceledOnTouchOutside(false);
            loadingbar.show();

            Validatephonenumber(name,phone,password);
        }
}

    private void Validatephonenumber(final String name, final String phone, final String password) {

        final DatabaseReference RootRef ;
        RootRef = FirebaseDatabase.getInstance().getReference();

        RootRef.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                if(!(dataSnapshot.child("Users").child(phone).exists())){

                    HashMap<String,Object> userdatamap = new HashMap<>();
                    userdatamap.put("phone",phone);
                    userdatamap.put("name",name);
                    userdatamap.put("password",password);

                    RootRef.child("Users").child(phone).updateChildren(userdatamap).addOnCompleteListener(new OnCompleteListener<Void>() {
                        @Override
                        public void onComplete(@NonNull Task<Void> task) {

                            if (task.isSuccessful()){
                                Toast.makeText(register.this, "Congratulations, Your account has been created..", Toast.LENGTH_SHORT).show();
                                loadingbar.dismiss();

                                Intent intent = new Intent(register.this,login.class);
                                startActivity(intent);
                            }

                            else
                            {
                                loadingbar.dismiss();
                                Toast.makeText(register.this, "Network Error, Please try again..", Toast.LENGTH_SHORT).show();

                            }
                        }
                    });
                }
                else
                {
                    Toast.makeText(register.this, "This "+ phone + "already exists..." , Toast.LENGTH_SHORT).show();
                    loadingbar.dismiss();

                    Intent intent = new Intent(register.this,MainActivity.class);
                    startActivity(intent);
                }
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });

    }
}

应该已经在firebase中创建了帐户。
