CodePudding user response：
else if(name.equals("admin") && password.equals("admin")
I think here is the problem. You are not using the variables you assigned for the inputs.
Name = name.getText().toString().trim();
Pass = password.getText().toString().trim();
if (!Name.equals("") && !Pass.equals("")) // changed to Name variable
...
else if(Name.equals("admin") && Pass.equals("admin") // changed to variables
maybe change the name of EditText and String to be more distinct to avoid misuses.
CodePudding user response：
i think it maybe because your first expresion in "if". that will make what ever you input password or name the result statment is true and doesnt enter to "else" statement and the other is variabel name case sensitif in if expresion name lowercase but before it declare with uppercase in first word.
Name = name.getText().toString().trim();
Pass = password.getText().toString().trim();
if (!name.equals("") && !Pass.equals("")) // changed to if (Name.equals("") && Pass.equals(""))
