>>you can write your code like

  if (TextUtils.isEmpty(username)) {
            editTextUserName.setError("Please enter username");
            editTextUserName.requestFocus();
            return;
        }

        if (TextUtils.isEmpty(password)) {
            editTextPassword.setError("Enter a password");
            editTextPassword.requestFocus();
            return;
        }
