 loginButton.setOnClickListener(new View.OnClickListener() {
            @Override

                String email=emailEditText.getText().toString();
                String password=passwordEditText.getText().toString();
                if (!email.equals("")&&!password.equals("")) {
                    if (isValid(email)) {
                    progressBar.setVisibility(View.VISIBLE);
                    loginButton.setEnabled(false);
                    firebaseAuth.signInWithEmailAndPassword(email, password)
