电话验证凭证

Question

我正在使用 PhoneAuthCredential，它工作正常，但我需要在将他重定向到家庭活动之前检查用户是否提供了一些数据，例如用户名和电子邮件，如果我没有找到这些数据，我必须将他重定向到注册活动，这样我就可以在他登录之前获取这些数据

public class VerifyPhoneActivity extends AppCompatActivity {

    private String verificationId;
    private FirebaseAuth mAuth;
    FirebaseAuth.AuthStateListener mAuthListener;

    DatabaseReference users;


    ProgressBar progressBar;
    TextInputEditText editText;
    AppCompatButton buttonSignIn;


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

        mAuth = FirebaseAuth.getInstance();

        progressBar = findViewById(R.id.progressbar);
        editText = findViewById(R.id.editTextCode);
        buttonSignIn = findViewById(R.id.buttonSignIn);

        String phoneNumber = getIntent().getStringExtra("phoneNumber");
        sendVerificationCode(phoneNumber);

        // save phone number
        SharedPreferences prefs = getApplicationContext().getSharedPreferences("USER_PREF",
                Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = prefs.edit();
        editor.putString("phoneNumber", phoneNumber);
        editor.apply();

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

                String code = editText.getText().toString().trim();

                if (code.isEmpty() || code.length() < 6) {

                    editText.setError("Enter code...");
                    editText.requestFocus();
                    return;
                }
                verifyCode(code);
            }
        });

    }

    private void verifyCode(String code) {
        PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, code);
        signInWithCredential(credential);
    }

    private void signInWithCredential(PhoneAuthCredential credential) {
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {

                            FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                            if(user!=null){
                                Intent intent = new Intent(VerifyPhoneActivity.this, DriverHome.class);
                                startActivity(intent);
                                finish();
                            }else {
                                Intent intent = new Intent(VerifyPhoneActivity.this, StartActivity.class);
                                startActivity(intent);
                                finish();
                            }

                        }else {
                            Toast.makeText(VerifyPhoneActivity.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
                            progressBar.setVisibility(View.GONE);
                        }
                    }
                });
    }

    private void sendVerificationCode(String number) {
        progressBar.setVisibility(View.VISIBLE);
        PhoneAuthProvider.getInstance().verifyPhoneNumber(
                number,
                60,
                TimeUnit.SECONDS,
                TaskExecutors.MAIN_THREAD,
                mCallBack
        );

        progressBar.setVisibility(View.GONE);
    }

    private PhoneAuthProvider.OnVerificationStateChangedCallbacks
            mCallBack = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {

        @Override
        public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
            super.onCodeSent(s, forceResendingToken);
            verificationId = s;
        }

        @Override
        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
            String code = phoneAuthCredential.getSmsCode();
            if (code != null) {
                editText.setText(code);
                verifyCode(code);
            }
        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Toast.makeText(VerifyPhoneActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
            progressBar.setVisibility(View.GONE);
        }
    };

}

这个问题不是很清楚。您希望从哪个活动中获得这些信息？

创建一个活动来获取用户的信息。 例如：-UserInformationActivity

在 java 文件中你可以创建一个 firebase 数据库节点来存储这些信息

数据库参考：

DatabaseReference userinfo=FirebaseDatabase.getInstance().getReference().child("User Info").child(FirebaseAuth.getInstance().getCureentUser().getUid());

使用Hashmap 将数据插入到节点中。

Hashmap hash = new Hashmap();
hash.put("Username", username);
hash.put("Email", email);
userinfo.updateChildren(hash);

在您的VerifyPhoneActivity 类中，当您成功验证用户身份时，检查该引用的数据快照是否存在于 firebase 数据库中。像这样更新VerifyPhoneActivity 类中的代码：

final DatabaseReference us=FirebaseDatabase.getInstance().getReference().child("User Info").child(FirebaseAuth.getInstance().getCurrentUser.getUid())

然后像这样更新你的 signInwithCredential() 方法：

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if(user!=null){
    us.addValueEventlistner(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            if(dataSnapshot.exists()){
                Intent intent = new Intent(VerifyPhoneActivity.this, DriverHome.class);
                startActivity(intent);
                finish(); }
            else{
                Intent gotoUserInfo=new Intent(VerifyPhoneActivity.this,UserInformationActivity.class);
                startActivity(gotoUserInfo);
                finish();
            } }
        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {
        }
    });
}
else {
    Intent intent = new Intent(VerifyPhoneActivity.this, StartActivity.class);
    startActivity(intent);
    finish();
}

希望这会有所帮助。谢谢！
