What is the alternative in Harmony OS for TypedArray in Android?

Question

In my project I want to retrieve the color value for the custom attributes at index. Like in android we have the TypedArray to do this functionality.

final TypedArray typedArray = mContext.obtainStyledAttributes(attrs, R.styleable.CustomCalendarView, 0, 0);
calendarBackgroundColor = typedArray.getColor(R.styleable.CustomCalendarView_calendarBackgroundColor, getResources().getColor(R.color.white));
calendarTitleBackgroundColor = typedArray.getColor(R.styleable.CustomCalendarView_titleLayoutBackgroundColor, getResources().getColor(R.color.white));
calendarTitleTextColor = typedArray.getColor(R.styleable.CustomCalendarView_calendarTitleTextColor, getResources().getColor(R.color.black));
weekLayoutBackgroundColor = typedArray.getColor(R.styleable.CustomCalendarView_weekLayoutBackgroundColor, getResources().getColor(R.color.white));
typedArray.recycle();

So we don't have TypedArray in Harmony OS. What is the way of doing this functionality?

You don't need TypedArray to retrieve custom attributes from AttributeSet in HarmonyOS, instead AttrSet API directly allows you to retrieve custom attributes.

    indicatorNormalColor = mAttrSet.getAttr(INDICATOR_NORMAL_COLOR).isPresent() ?
            mAttrSet.getAttr(INDICATOR_NORMAL_COLOR).get().getColorValue() : defaultIndicatorNormalColor;
    indicatorSelectedColor = mAttrSet.getAttr(INDICATOR_SELECTED_COLOR).isPresent() ?
            mAttrSet.getAttr(INDICATOR_SELECTED_COLOR).get().getColorValue() : defaultIndicatorSelectedColor;
    indicatorStrokeColor = mAttrSet.getAttr(INDICATOR_STROKE_COLOR).isPresent() ?
            mAttrSet.getAttr(INDICATOR_STROKE_COLOR).get().getColorValue() : defaultIndicatorStrokeColor;
    indicatorNormalStrokeWidth = mAttrSet.getAttr(INDICATOR_NORMAL_STROKE_WIDTH).isPresent() ?
            mAttrSet.getAttr(INDICATOR_NORMAL_STROKE_WIDTH).get().getDimensionValue() : defaultIndicatorNormalStrokeWidth;
    indicatorSelectedStrokeWidth = mAttrSet.getAttr(INDICATOR_SELECTED_STROKE_WIDTH).isPresent() ?
            mAttrSet.getAttr(INDICATOR_SELECTED_STROKE_WIDTH).get().getDimensionValue() :
