Answer 1

Ho aggiunto Butterknife-5.0.0-Snapshot.jar, in precedenza stavo usando JAR da http://jakewharton.github.io/butterknife/ versione 4.0.1.

Alla fine il codice di esempio funziona bene

Cosa ho fatto è

1) Elaborazione di annotazione abilitata

2) Solo abilitare l'elaborazione delle annotazioni in Eclipse non è sufficiente.deve indicarlo alla biblioteca che farà l'elaborazione effettiva.
