Please refer to the last AppCompatView. Next is the Login.class where everything seemed to crush because of the TextViewLinkRegister
public class LoginActivity extends AppCompatActivity implements View.OnClickListener {
    private final AppCompatActivity activity = LoginActivity.this;
    private NestedScrollView nestedScrollView;
    private TextInputLayout textInputLayoutEmail;
    private TextInputLayout textInputLayoutPassword;
    private TextInputEditText textInputEditTextEmail;
    private TextInputEditText textInputEditTextPassword;

    private AppCompatTextView textViewLinkRegister;
    private InputValidation inputValidation;
    private DatabaseHelper databaseHelper;
    @Override

        initViews();

        initObjects();
    }
    /**

    private void initViews() {
        nestedScrollView = (NestedScrollView) findViewById(R.id.nestedScrollView);

        textInputEditTextEmail = (TextInputEditText) findViewById(R.id.textInputEditTextEmail);

        appCompatButtonLogin = (AppCompatButton) findViewById(R.id.appCompatButtonLogin);

    }
    /**

    private void initListeners() {
        appCompatButtonLogin.setOnClickListener(this);
        textViewLinkRegister.setOnClickListener(this);
    }
    /**

    private void initObjects() {
        databaseHelper = new DatabaseHelper(activity);

    }
    @Override

        switch (v.getId()) {
            case R.id.appCompatButtonLogin:

                break;
            case R.id.appCompatTextViewRegisterLink:
                // Navigate to RegisterActivity
                Intent intentRegister = new Intent(getApplicationContext(), RegisterActivity.class);
                startActivity(intentRegister);
                break;
        }
    }
    /**
     * This method is to validate the input text fields and verify login credentials from SQLite
     */
    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(textInputEditTextPassword, textInputLayoutPassword, getString(R.string.error_message_email))) {
            return;
        }
        if (databaseHelper.checkUser(textInputEditTextEmail.getText().toString().trim()
                , textInputEditTextPassword.getText().toString().trim())) {
            Intent accountsIntent = new Intent(activity, UsersActivity.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);
    }
}
I have tried all the combinations and I lost it. 
private AppCompatTextView textViewLinkRegister; is the problem and it's not working if changed to AppCompatTextViewLinkRegister.
What else can I do?
