java - 登录后引导用户进行某些 Activity

Question

我有一个拥有用户名、电子邮件、密码和权限的用户。基本上我想要的是在成功登录后，我想以具有某一项 Activity 权限 0001 的用户和另一项 Activity 具有 0002 权限的用户为例。这是我登录的方法。但是当我尝试添加诸如“如果权限为 0001 然后创建新 Intent ”之类的内容时，我收到错误“电子邮件或密码无效”

private void verifyFromSQLite() {
    if (!inputValidation.isInputEditTextFilled(textInputEditTextEmail, textInputLayoutEmail, getString(R.string.error_message_email))) {
        return;
    }
    if (!inputValidation.isInputEditTextEmail(textInputEditTextEmail, textInputLayoutEmail, getString(R.string.error_message_email))) {
        return;
    }
    if (!inputValidation.isInputEditTextFilled(textInputEditTextPermission, textInputLayoutPermission, getString(R.string.error_message_email))) {
        return;
    }
    if (!inputValidation.isInputEditTextFilled(textInputEditTextPassword, textInputLayoutPassword, getString(R.string.error_message_email))) {
        return;
    }


    if (databaseHelper.checkUser(textInputEditTextEmail.getText().toString().trim()
            , textInputEditTextPassword.getText().toString().trim(),textInputEditTextPermission.getText().toString().trim())) {


        Intent accountsIntent = new Intent(activity, UsersListActivity.class);
        accountsIntent.putExtra("EMAIL", textInputEditTextEmail.getText().toString().trim());
        emptyInputEditText();
        startActivity(accountsIntent);


    } else {
        // Snack Bar to show success message that record is wrong
        Snackbar.make(nestedScrollView, getString(R.string.error_valid_email_password), Snackbar.LENGTH_LONG).show();
    }
}

/**
 * This method is to empty all input edit text
 */
private void emptyInputEditText() {
    textInputEditTextEmail.setText(null);
    textInputEditTextPassword.setText(null);
    textInputEditTextPermission.setText(null);
}

好吧，这很简单，从 EditText 获取值并在激活它之前运行一组条件语句来操纵它的 Intent :

final String permission = textInputEditTextPermission.getText().toString().trim();
final String email = textInputEditTextEmail.getText().toString().trim();

emptyInputEditText();

if (permission.equals("1")) {
    accountsIntent = new Intent(activity, UsersListActivity.class);
} else if (permission.equals("2")) {
    accountsIntent = new Intent(activity, OtherActivity.class);
} else {
    accountsIntent = new Intent(activity, AnotherActivity.class);
}

accountsIntent.putExtra("EXTRA_EMAIL", email);   
startActivity(accountsIntent);
