Can you show an example of how you would use it?

New to RxJava and RxAndroid, I started out by doing some user input
validation previously implemented via TextWatcher. I realized while
attempting to leverage the filter operator that the Observable returned
from RxTextView.textChanges only emits the new text. Would it be
beneficial to add a similar Observable that also emitted the before value
(from TextWatcher#beforeTextChanged
https://developer.android.com/reference/android/text/TextWatcher.html#beforeTextChanged%28java.lang.CharSequence,%20int,%20int,%20int%29
)?—

I was thinking something like:
RxTextView.textChangesWithBefore(textView)
.filter(this::compareBeforeAndAfter)
.subscribe(beforeAndAfterPair -> {
// ...
});
Just imagining Pair
in the example here, haven't put much thought into the best way to represent the two values.

Got it. Will look into adding.

Cool, thanks for considering it.

@wKovacs64 Both before and after text change event bindings are added in #145.
You can then use combine operators with filter to do the job.
