android - 如何修复 Parse 中的“无效用户名/密码”

Question

我正在开发一个应用程序，它有 signup 和 Login 使用解析服务器，我可以在其中注册但是当我尝试登录时它给了我异常

"Invalid username/password"

这是 signUp 和 LogIn 的代码，当 signUpMode 处于 Activity 状态时，用户通过按下按钮进行注册，或者当 signUpmode 处于停用状态时，即 false 按钮​​充当登录，用户可以登录，但是当我尝试登录时，它说 “无效的用户名/密码”

  public void signUp(View view)
        {
            editTextUser =(EditText) findViewById(R.id.userNameEdit);
            editTextPass =(EditText) findViewById(R.id.passWordEdit);

                if(editTextUser.getText().toString().matches("") || editTextPass.getText().toString().matches(""))
                {
                    Toast.makeText(this,"Username and Password required",Toast.LENGTH_SHORT).show();
                }
                else
                {
                    if(SignupModeActive)
                    {
                        ParseUser user = new ParseUser();
                        user.setUsername(editTextUser.getText().toString());
                        user.setPassword(editTextUser.getText().toString());
                        user.signUpInBackground(new SignUpCallback() {
                            @Override
                            public void done(ParseException e) {

                                    if(e == null)
                                    {
                                        Log.i("saveInBackGround","SignUp Success");
                                        Intent intent = new Intent(MainActivity.this,UserslistActivity.class);
                                        startActivity(intent);
                                    }
                                    else{
                                        Toast.makeText(MainActivity.this,e.getMessage(),Toast.LENGTH_SHORT).show();
                                    }


                            }
                        });


                    }
                    else
                    {
                            ParseUser.logInInBackground(editTextUser.getText().toString(),editTextPass.getText().toString(), new LogInCallback() {
                                @Override
                                public void done(ParseUser user, ParseException e) {
                                    if(user != null){
                                        Log.i("LogInBackGround","Login Succesfull");
                                        Intent logInintent = new Intent(MainActivity.this,UserslistActivity.class);
                                        startActivity(logInintent);
                                    }
                                    else
                                    {
                                        Toast.makeText(MainActivity.this,e.getMessage(),Toast.LENGTH_LONG).show();
                                    }
                                }
                            });
                        }


                    }
