Custom Theme Creation

[JoseZamora97]

Hi!,
I am trying to create a custom theme from DEFAULT theme but nothing changes.

This is my method that sets the codeview up.

public void setUpCodeView() {

        codeView = findViewById(R.id.code_view);

        int colorAccent = getResources().getColor(R.color.colorAccent);
        int colorPrimary = getResources().getColor(R.color.colorPrimary);

        int colorPrimaryDark = getResources().getColor(R.color.colorPrimaryDark);
        int colorTitles= getResources().getColor(R.color.colorTitles);
        int colorBodies= getResources().getColor(R.color.colorBodies);

        SyntaxColors syntaxColors = new SyntaxColors(
                colorAccent, colorAccent, colorBodies, colorPrimaryDark,
                colorTitles, colorTitles, colorBodies, colorBodies,
                colorTitles, colorTitles, colorBodies
        );

        ColorThemeData myTheme = ColorTheme.DEFAULT.theme()
                .withSyntaxColors(syntaxColors);

        codeView.setOptions(Options.Default.get(this)
                .withTheme(myTheme)
                .withFont(Objects.requireNonNull(ResourcesCompat.getFont(this,
                        R.font.nunito))));
    }

And this is the line where I set code to the codeView

codeView.setCode(myText, "py");

The text appears but there is no code highlight and theme doesnt change.

Ty for help!.
