RxBinding

RxBinding is a set of libraries that allow you to react to user interface events via the RxJava paradigm. Let’s take a look at a few examples.

Button click event:

Button b = (Button)findViewById(R.id.button);
Subscription buttonSub =
                RxView.clicks(b).subscribe(new Action1<Void>() {
                    @Override
                    public void call(Void aVoid) {
                        // do some work here
                    }
                });
// make sure to unsubscribe the subscription

Text change listener for an EditText:

final EditText name = (EditText) v.findViewById(R.id.name);
Subscription editTextSub =
    RxTextView.textChanges(name)
            .subscribe(new Action1<String>() {
                @Override
                public void call(String value) {
                    // do some work with the updated text
                }
            });
// Make sure to unsubscribe the subscription
