我想要改变android中选项菜单的自定义字体(如: Centuary，Raleway Regular )

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:app="http://schemas.android.com/apk/res-auto">
    <font
        app:fontStyle="normal"
        app:fontWeight="400"
        app:font="@font/raleway_regular" />
</font-family>

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.your_menu, menu);

    // 获取字体资源的路径
    String fontPath = "fonts/font.xml";

    // 遍历菜单项，设置字体
    for (int i = 0; i < menu.size(); i++) {
        MenuItem menuItem = menu.getItem(i);
        SpannableString spannableString = new SpannableString(menuItem.getTitle());
        spannableString.setSpan(new TypefaceSpan(this, fontPath), 0, spannableString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        menuItem.setTitle(spannableString);
    }

    return true;
}

import android.content.Context;
import android.graphics.Typeface;
import android.text.TextPaint;
import android.text.style.MetricAffectingSpan;

public class TypefaceSpan extends MetricAffectingSpan {
    private Typeface typeface;

    public TypefaceSpan(Context context, String fontPath) {
        typeface = Typeface.createFromAsset(context.getAssets(), fontPath);
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        apply(ds);
    }

    @Override
    public void updateMeasureState(TextPaint paint) {
        apply(paint);
    }

    private void apply(TextPaint paint) {
        Typeface oldTypeface = paint.getTypeface();
        int oldStyle = oldTypeface != null ? oldTypeface.getStyle() : 0;
        int fakeStyle = oldStyle & ~typeface.getStyle();

        if ((fakeStyle & Typeface.BOLD) != 0) {
            paint.setFakeBoldText(true);
        }

        if ((fakeStyle & Typeface.ITALIC) != 0) {
            paint.setTextSkewX(-0.25f);
        }

        paint.setTypeface(typeface);
    }
}
