This code works:

    Dialog dlg = new Dialog(thisAct, R.style.DialogTheme);
    dlg.setContentView(view);
    dlg.setCancelable(false);
    dlg.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
    dlg.setOnKeyListener((arg0, keyCode, event) -> {
        Timber.d("onKey(%d)", keyCode);
        //{home intercepting
        if ((keyCode == KeyEvent.KEYCODE_HOME)) {
            Timber.i("HOME pressed");
            return true;
        }

        return true;
    });
    dlg.show();

Answer 2

Override method onBackPressed() in your own dialog and use it in your code:

public class MyDialog extends Dialog {

    public MyDialog(@NonNull Context context) {
        super(context);
    }

    @Override
    public void onBackPressed() {
        // Do what you want
    }
}

Use:

MyDialog dlg = new MyDialog(context);
dlg.show();
