Then on Butterknife's official website to see the solution: http://jakewharton.github.io/butterknife/ide-eclipse.html
1. Because you are using ADT, the Java compiler→annotation processing and check "Enable Project specific Settings" in the setup of the project .
2. Expand annotation processing and select Factory Path. Tick "Enable Project specific Settings" and click Add JARs ..., select the Butterknife jar package
3. Then click OK to save the settings, and eclipse will ask if you want to rebuild the new project and click Yes.
4. Make sure that you have a. apt_generated folder in the root directory of your project, and that the folder contains files such as youractivity$ $ViewInjector. java.
5. Make sure that Java version is a minimum of 1.6.
