Button registerButton = (Button) findViewById(R.id.registerButton);        registerButton.setOnClickListener(new View.OnClickListener() {              @Override            public void onClick(View view) {                String userID = idText.getText().toString();                String userPassword = passwordText.getText().toString();                String userSport = spinner.getSelectedItem().toString();                String userEmail = emailText.getText().toString();                  if(!validate)                {                    AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);                    dialog = builder.setMessage("중복 체크를 해주세요.")                            .setNegativeButton("확인", null)                            .create();                    dialog.show();                    return;                }                  if(userID.equals("") || userPassword.equals("") || userSport.equals("") || userEmail.equals("") || userGender.equals("")) {                    AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);                    dialog = builder.setMessage("빈 칸 없이 입력해주세요.")                            .setNegativeButton("확인", null)                            .create();                    dialog.show();                    return;                }                  Response.Listener<String> responseListener = new Response.Listener<String>() {                      @Override                    public void onResponse(String response) {                        try                        {                            JSONObject jsonResponse = new JSONObject(response);                            boolean success = jsonResponse.getBoolean("success");                            if(success) {                                AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);                                dialog = builder.setMessage("회원 가입에 성공했습니다.")                                        .setPositiveButton("확인", null)                                        .create();                                dialog.show();                                finish();                            }                            else {                                AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);                                dialog = builder.setMessage("회원 가입에 실패했습니다.")                                        .setNegativeButton("확인", null)                                        .create();                                dialog.show();                            }                        }                        catch (Exception e)                        {                            e.printStackTrace();                        }                    }                };                RegisterRequest registerRequest = new RegisterRequest(userID, userPassword, userGender, userSport, userEmail, responseListener);                RequestQueue queue = Volley.newRequestQueue(RegisterActivity.this);                queue.add(registerRequest);            }        });    }

이런식으로 코딩을 했는데 중복체크 누를시 다른거는 메세지 다 나오는데 안에 아이디를 넣었을 시 중복체크가 안눌려요 뭐가 문제인거죠..?ㅠ
그리고 또 하나 ! 가입하기를 누를 시 나오는 메세지가 0.5초만에 켜졌다가 로그인화면으로 넘어가는데 뭐가 문제인지 모르겠어요 ㅠㅠ
이 두 문제로 사흘동안 고민했는데 도저히 모르겠어서 물어봅니다 도와주세요 !! ㅠ
