You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

Example:

	private void drawLabels(Canvas canvas) {
	weekWidth = (getWidth () - getPaddingLeft () - getPaddingRight ()) / weeksCount;
	graphHeight = getHeight () - getPaddingTop () - getPaddingBottom ();


	float centerX = getPaddingLeft() + (weekWidth/2);

	for(int i=0;i<weeksCount;i++) {
	String week = "week "+i;
	mTextPaint.getTextBounds(week, 0, week.length(), textBounds);
