Multiple Decorators with different colours

Hey there,

I want to set the background of some dates to different color. For example I want to set the background of the 20.7.17 and of the 24.7.17 to red and the background of the 26. and 30. to green. I tried to do this with multiple decorators, but they only color the dates in one color. Is there a possibility to do this ?asd

I used addDecorators and my decorator class looks like this:

private final int mColor;
private final HashSet<CalendarDay> dates;
private Context mContext;

EventDecorator(int color, Collection<CalendarDay> dates, Context context) {
    this.mColor = color;
    this.dates = new HashSet<>(dates);
    this.mContext = context;
}

@Override
public boolean shouldDecorate(CalendarDay day) {
    return dates.contains(day);
}

@Override
public void decorate(DayViewFacade view) {
    GradientDrawable drawable = (GradientDrawable) ResourcesCompat.getDrawable(mContext.getResources(), R.drawable.circle, null);
    if (drawable != null) {
        drawable.setColor(mColor);
        view.setBackgroundDrawable(drawable);

    }

}

Hi LeonBre,

I think I might be able to help you out, considering I was stuck myself and had to go through the whole calendar code.

A DayViewDecorator is an interface that has only two methods you need to implement, shouldDecorate(CalendarDay) and decorate(DayViewFacade). shouldDecorate() is called for every date in the calendar to determine if the decorator should be applied to that date. decorate() is called only one time to gather the customizations used for this decorator. This is so we can cache the decorations and efficiently apply them to many days.

As per docs the decorator method only is called ones and is cached after that, the color cannot be different within the same decorator. However creating multiple decorators with each a color should have worked, I did the same with my calendar and it works for me. (Unless I misunderstood you)

Hope this helps.

@ka05 you are correct, the issue is related on how the spans are added. Im not a big fan of spans in general due to the limitation of customizing them, but they are more efficient for performance and less prone to weird behavior. If any of you find a way to add the dot spans without having them overlapping each other (and not breaking other spans), please let me know.
