How to set different drawables in same selector

I need a custom selector for range selection in which I could set different drawables if the date is the first selected, last selected, or in the middle. Since the decorator doesn’t expose current date in decorate how can I achieve that. Cheers!

That’s essentially all it is. I managed to find that code:

private class RangeSelectionLeftDecorator(
        private val leftDate: LocalDate,
        private val leftDrawable: Drawable
) : DayViewDecorator {

    override fun shouldDecorate(day: CalendarDay): Boolean {
        return leftDate == day.date
    }

    override fun decorate(view: DayViewFacade) {
        view.setSelectionDrawable(leftDrawable)
        view.addSpan(ForegroundColorSpan(Color.WHITE))
    }

}

private class RangeSelectionMiddleDecorator(
        private val middleDates: Set<LocalDate>,
        private val middleDrawable: Drawable
) : DayViewDecorator {

    override fun shouldDecorate(day: CalendarDay): Boolean {
        return day.date in middleDates
    }

    override fun decorate(view: DayViewFacade) {
        view.setSelectionDrawable(middleDrawable)
        view.addSpan(ForegroundColorSpan(Color.BLACK))
    }

}

private class RangeSelectionRightDecorator(
        private val rightDate: LocalDate,
        private val rightDrawable: Drawable
) : DayViewDecorator {

    override fun shouldDecorate(day: CalendarDay): Boolean {
        return rightDate == day.date
    }

    override fun decorate(view: DayViewFacade) {
        view.setSelectionDrawable(rightDrawable)
        view.addSpan(ForegroundColorSpan(Color.WHITE))
    }

}

The color spans were to adjust text color from memory. It’s been a while since I’ve looked at this.

Left Drawable:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:gravity="center_vertical|right" android:left="@dimen/cal_tile_height_half">
        <shape android:shape="rectangle">
            <solid android:color="@color/[surface color]"/>
        </shape>
    </item>
    <item android:gravity="center">
        <shape android:shape="oval">
            <solid android:color="@color/[decorator color]"/>
            <size android:height="@dimen/cal_tile_height" android:width="@dimen/cal_tile_height"/>
        </shape>
    </item>
</layer-list>

Middle drawable:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:gravity="center">
        <shape android:shape="rectangle">
            <solid android:color="@color/[surface color]"/>
        </shape>
    </item>
</layer-list>

Right drawable:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:gravity="center_vertical|left" android:right="@dimen/cal_tile_height_half">
        <shape android:shape="rectangle">
            <solid android:color="@color/[surface color]"/>
        </shape>
    </item>
    <item android:gravity="center">
        <shape android:shape="oval">
            <solid android:color="@color/[decorator color]"/>
            <size android:width="@dimen/cal_tile_height" android:height="@dimen/cal_tile_height"/>
        </shape>
    </item>
</layer-list>

See the applyForSelection() method in the earlier comment. Create the RangeSelectionDecorator and keep a reference to it, then call that method whenever the selection changes on the calendar. It’s a bit of a misnomer as it’s really more of a helper class
