我正在制作一个购物应用程序，并且我即将完成该应用程序。但我毕竟想添加忘记密码功能。我可以使用 FirebaseAuth 来完成此操作，但对于注册和登录，我没有使用 FirebaseAuth。

我的用户详细信息将直接进入 Firebase 数据库并保存在“用户”表中。由于我是 Android 应用程序开发新手，我不知道如何使用忘记密码功能来实现我的应用程序。

这是我的数据库结构:

这是我的注册 Activity :

public class RegisterActivity extends AppCompatActivity {

    private Button CreateAccountButton;
    private EditText InputUsername, InputPhoneNumber, InputPassword, InputRePassword, InputEmail, InputName;
    private ProgressDialog loadingBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);
        CreateAccountButton = (Button) findViewById(R.id.register_btn);
        InputUsername = (EditText) findViewById(R.id.register_username);
        InputPhoneNumber = (EditText) findViewById(R.id.register_Number);
        InputPassword = (EditText) findViewById(R.id.register_password);
        InputRePassword = (EditText) findViewById(R.id.register_repassword);
        InputEmail = (EditText) findViewById(R.id.register_email);
        InputName = (EditText) findViewById(R.id.register_name);
        loadingBar = new ProgressDialog(this);
        CreateAccountButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                CreateAccount();
            }
        });
    }

    private void CreateAccount() {
        String name = InputName.getText().toString();
        String username = InputUsername.getText().toString();
        String phone = InputPhoneNumber.getText().toString();
        String password = InputPassword.getText().toString();
        String repassword = InputRePassword.getText().toString();
        String email = InputEmail.getText().toString();

        if (TextUtils.isEmpty(name)) {
            Toast.makeText(this, "Please enter your Name", Toast.LENGTH_SHORT).show();
        } else if (TextUtils.isEmpty(username)) {
            Toast.makeText(this, "Please enter your Username", Toast.LENGTH_SHORT).show();
        } else if (TextUtils.isEmpty(phone)) {
            Toast.makeText(this, "Please enter your Phone Number", Toast.LENGTH_SHORT).show();
        } else if (TextUtils.isEmpty(password)) {
            Toast.makeText(this, "Please enter your Password", Toast.LENGTH_SHORT).show();
        } else if (TextUtils.isEmpty(repassword)) {
            Toast.makeText(this, "Please re-enter your Password", Toast.LENGTH_SHORT).show();
        } else if (TextUtils.isEmpty(email)) {
            Toast.makeText(this, "Please enter your Email", Toast.LENGTH_SHORT).show();
        } else {
            loadingBar.setTitle("Creating Account");
            loadingBar.setMessage("Please wait.");
            loadingBar.setCanceledOnTouchOutside(false);
            loadingBar.show();
            ValidatephoneNumber(username, name, phone, password, repassword, email);
        }
    }

    private void ValidatephoneNumber(final String username, final String name, final String phone, final String password, final String repassword, final String email)
    {
        final DatabaseReference RootRef;
        RootRef = FirebaseDatabase.getInstance().getReference();
        RootRef.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot)
            {
                if(!(dataSnapshot.child("Users").child(username).exists()))
                {
                    HashMap<String, Object> userdataMap = new HashMap<>();
                    userdataMap.put("username", username);
                    userdataMap.put("name", name);
                    userdataMap.put("phone", phone);

                                {
                                    if(task.isSuccessful())
                                    {
                                        Toast.makeText(RegisterActivity.this, "Your account has been created!", Toast.LENGTH_SHORT).show();
                                        loadingBar.dismiss();
                                        Intent intent = new Intent(RegisterActivity.this, LoginActivity.class);
                                        startActivity(intent);
                                    }
                                    else
                                    {
                                        loadingBar.dismiss();
                                        Toast.makeText(RegisterActivity.this, "Connection Error. Please try again.", Toast.LENGTH_SHORT).show();
                                    }
                                }
                            });
                }
                else

            {
            }
        });
    }
}

这是我的登录 Activity :

我可以知道如何实现我的忘记密码功能的代码吗？我非常感谢您的帮助!

这是内置于 firebase 中的:

FirebaseAuth.getInstance().sendPasswordResetEmail("user@example.com")
