        btn_login = findViewById(R.id.btn_login);
        btn_login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String email = edtEmail.getText().toString();
                String pass = edtPass.getText().toString();
                Intent intent = new Intent(kakaoLoginActivity.this,LoginResultActivity.class);
                intent.putExtra("email",email);
                intent.putExtra("pass",pass);

                startActivity(intent);
            }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login_result);
        Intent intent = getIntent();
        
        String email =  intent.getStringExtra("email");
        String pass =  intent.getStringExtra("pass");
        text12 = findViewById(R.id.tvLoginResult);

        if (email.equals("123") && pass.equals("123")){
            text12.setText("로그인 성공");
        }else{
            text12.setText("로그인 실패");
