アンドロイドのユーザーサインアップ活動にfirebaseを使用する

Question

申し込みをしようとしていますが、データを保存しようとしているときにFirebase Databaseが動作していません。

Manifestにすべての依存関係とインターネットのアクセス許可を追加しました。

私が間違っているの何を以下の私の基本的なコードで、教えてください：

public class SignUp extends AppCompatActivity { 


private EditText mUserNameField; 
private EditText mUserEmailField; 
private EditText mUserPasswordField; 
private Button mUserRegisterButton; 

private FirebaseAuth mAuth; 
private ProgressDialog mProgress; 
private DatabaseReference mDataBase; 

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

    mAuth=FirebaseAuth.getInstance(); 
    mDataBase= FirebaseDatabase.getInstance().getReference().child("Users"); 

    mProgress=new ProgressDialog(this); 

    mUserNameField=(EditText)findViewById(R.id.usernameField); 
    mUserEmailField=(EditText) findViewById(R.id.userEmailField); 
    mUserPasswordField=(EditText) findViewById(R.id.userpasswordField); 
    mUserRegisterButton=(Button) findViewById(R.id.signupB3); 

    mUserRegisterButton.setOnClickListener(new View.OnClickListener(){ 
     @Override 
     public void onClick(View view) { 
      startRegister(); 
     } 
    }); 



    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
} 

private void startRegister() { 

    final String name=mUserNameField.getText().toString().trim(); 
    String email=mUserEmailField.getText().toString().trim(); 
    String password=mUserPasswordField.getText().toString().trim(); 

    if(!TextUtils.isEmpty(name)&& !TextUtils.isEmpty(email)&& !TextUtils.isEmpty(password)) { 

     mProgress.setMessage("Signing Up..."); 
     mProgress.show(); 

     mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() { 
      @Override 
      public void onComplete(@NonNull Task<AuthResult> task) { 
       if (task.isSuccessful()) { 

        String user_id = mAuth.getCurrentUser().getUid(); 
        DatabaseReference current_user_db = mDataBase.child(user_id); 
        current_user_db.child("name").setValue(name); 
        current_user_db.child("image").setValue("default"); 
        mProgress.dismiss(); 

        Intent mainIntent=new Intent(SignUp.this,CreateTour.class); 
        mainIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
        startActivity(mainIntent); 
       } 
      } 
     }); 
    } 
} 
} 

Answer 1

public class Signup extends AppCompatActivity implements View.OnClickListener { 
    Button btnSignup; 
    TextView btnLogin,btnForgotPass; 
    EditText input_email,inpur_pass; 
    RelativeLayout sign_up; 

    private FirebaseAuth auth; 
    Snackbar snackbar; 

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


     btnSignup =(Button)findViewById(R.id.sign_button_register); 
     btnLogin=(TextView)findViewById(R.id.signup_btn_login); 
     btnForgotPass=(TextView)findViewById(R.id.signup_btn_forgot_pass); 
     input_email=(EditText)findViewById(R.id.singup_email); 
     inpur_pass=(EditText)findViewById(R.id.sign_password); 
     sign_up=(RelativeLayout)findViewById(R.id.sign_up); 

     btnSignup.setOnClickListener(this); 
     btnLogin.setOnClickListener(this); 
     btnForgotPass.setOnClickListener(this); 

     //init FireBase 
     auth=FirebaseAuth.getInstance(); 
    } 

    @Override 
    public void onClick(View v) { 
     if(v.getId()==R.id.signup_btn_login){ 
      startActivity(new Intent(Signup.this,MainActivity.class)); 
     }else if(v.getId()==R.id.signup_btn_forgot_pass){ 
      startActivity(new Intent(Signup.this,ForgotPass.class)); 
     }else if(v.getId()==R.id.sign_button_register){ 
      SignUpUser(input_email.getText().toString(),inpur_pass.getText().toString()); 
     } 

    } 

    private void SignUpUser(String email, String passeord) { 

     auth.createUserWithEmailAndPassword(email, passeord). 
       addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { 
        @Override 
        public void onComplete(@NonNull Task<AuthResult> task) { 
        if(!task.isSuccessful()){ 
         snackbar=Snackbar.make(sign_up,"Error"+task.getException(),Snackbar.LENGTH_LONG); 
         snackbar.show(); 
        } 
        else { 
         snackbar=Snackbar.make(sign_up,"Register Successfully",Snackbar.LENGTH_LONG); 
         snackbar.show(); 
        } 
        } 
       }); 
    } 
} 

このコードは完全に仕事です。 Fire-baseにプロジェクトを登録するときに、Fire-baseによって生成された、プロジェクトにj sonファイルもインクルードする必要があります。

これはXMLファイルです。
