Androidx Guideline can't be cast to ViewGroup

Question

I just migrate to androidx and I got and error like this

androidx.constraintlayout.widget.Guideline cannot be cast to android.view.ViewGroup

It's working fine before I migrate my code to androidx.

I already check some solution about this casting problem, but mostly they have a small mistake like casting a layout inside the button. And I already did some research and got a conclusion that this error showing because the androidx Guideline not a child of ViewGroup. But I can't find the solution yet for this one.

I include my xml and java code below

SettingAccActivity.java

protected void onCreate(@Nullable Bundle savedInstanceState) {
    setContext(this);
    updateSharedPref(PreferenceConnector.ACTIVITY, this.getClass().getSimpleName());
    super.onCreate(savedInstanceState);
    FrameLayout contentFrameLayout = findViewById(R.id.frame_content);
    LayoutInflater inflater = (LayoutInflater) this.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
    inflater.inflate(R.layout.activity_settings_acc, contentFrameLayout);
... }

Note : error is on inflater.inflate(R.layout.activity_settings_acc, contentFrameLayout);

I already find the solution. When I adjust the layout from android to androidx there's a wrong update. I change the old ConstraintLayout to Guideline
