View Click

Instead of the verbose setOnClickListener:

RxView.clicks(submitButton).subscribe(o -> log("submit button clicked!"));

Filter even numbers

Observable
    .just(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

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:

	package be.brol

	import android.os.Binder
	import android.os.Bundle
	import android.support.v4.app.BundleCompat
	import android.support.v4.app.Fragment

	/**
	* Eases the Fragment.newInstance ceremony by marking the fragment's args with this delegate
	* Just write the property in newInstance and read it like any other property after the fragment has been created

	import android.text.SpannableStringBuilder;
	import java.util.ArrayDeque;
	import java.util.Deque;

	import static android.text.Spanned.SPAN_INCLUSIVE_EXCLUSIVE;

	/** A {@link SpannableStringBuilder} wrapper whose API doesn't make me want to stab my eyes out. */
	public class Truss {
	private final SpannableStringBuilder builder;
	private final Deque<Span> stack;

	public ColorFilter duotoneColorFilter(@ColorInt int colorBlack, @ColorInt int colorWhite, float contrast) {
	ColorMatrix cm = new ColorMatrix();

	ColorMatrix cmBlackWhite = new ColorMatrix();
	float lumR = 0.2125f;
	float lumG = 0.7154f;
	float lumB = 0.0721f;
	float[] blackWhiteArray = new float[]{
	lumR, lumG, lumB, 0, 0,
	lumR, lumG, lumB, 0, 0,
