CHANGELOG.md

Change Log

Version 8.5.1 (2017-01-24)

• Fix: Tweak bundled ProGuard rules to only retain the two-argument constructor accessed via reflection.

Version 8.5.0 (2017-01-23)

• Emit @SuppressLint when using @OnTouch to avoid a lint warning.
• Migrate lint checks from Lombok AST to JetBrains PSI.
• Annotations are no longer claimed by the processor.
• Based on the minimum SDK version (as specified by butterknife.minSdk until http://b.android.com/187527 is released) the generated code now changes to use newer APIs when available.
• Generated classes now include single-argument overloads for View, Activity, and Dialog subclasses.
• Generated classes are no longer generic.
• Minimum supported SDK is now 9.

Version 8.4.0 (2016-08-26)

• New: @BindFloat annotation for dimensions whose format is of type 'float'. See the annotation for more information.
• Generated constructors are now annotated with @UiThread and non-final, base classes unbind() methods are annotated with @CallSuper.

Version 8.3.0 (2016-08-23)

• New: Support for Jack compiler in application projects.
• Fix: Generate ~20% less code and ~40% less methods.
• Fix: Allow @BindView to reference types which are generated by other annotation processors.
• Experimental: The generated view binding class can now be used directly. This allows ProGuard shrinking, optimization, and obfuscation to work without any rules being needed. For a class Test, the binding class will be named Test_ViewBinding. Calling its constructor will bind the instance passed in, and the create object is also the implementation of Unbinder that can be used to unbind the views. Note: The API of this generated code is subject to backwards-incompatible changes until v9.0.

Version 8.2.1 (2016-07-11)

• Fix: Do not emit android.R imports in generated code.
• Fix: Ensure the processor does not crash when scanning for R classes. This can occur when used in a Kotlin project.

Version 8.2.0 (2016-07-10)

• New: Support for library projects. Requires application of a Butter Knife Gradle plugin. See README for details.
• New: Generated code now emits R references instead of raw integer IDs.
• Fix: @OnPageChange listener binding now uses the 'add'/'remove' methods on ViewPager instead of 'set'.

Version 8.1.0 (2016-06-14)

• New: Change the structure of generated view binders to optimize for performance and generated code. This should result in faster binding (not that it's slow) and a reduction of methods.
• Fix: Call the correct method on TextView to unbind @OnTextChanged uses.
• Fix: Properly handle package names which contain uppercase letters.

Version 8.0.1 (2016-04-27)

• Fix: ProGuard rules now prevent obfuscation of only types which reference ButterKnife annotations.
• Eliminate some of the generated machinery when referenced from final types.

Version 8.0.0 (2016-04-25)

• @Bind becomes @BindView and @BindViews (one view and multiple views, respectively).

• Calls to bind now return an Unbinder instance which can be used to null references. This replaces the unbind API and adds support for being able to clear listeners.

• New: @BindArray binds String, CharSequence, and int arrays and TypeArray to fields.

• New: @BindBitmap binds Bitmap instances from resources to fields.

• @BindDrawable now supports a tint field which accepts a theme attribute.

• The runtime and compiler are now split into two artifacts.

  compile 'com.jakewharton:butterknife:8.0.0'
  apt 'com.jakewharton:butterknife-compiler:8.0.0'

• New: apply overloads which accept a single view and arrays of views.

• ProGuard rules now ship inside of the library and are included automatically.

• @Optional annotation is back to mark methods as being optional.

Version 7.0.1 (2015-06-30)

• Fix: Correct ClassCastException which occurred when @Nullable array bindings had missing views.

Version 7.0.0 (2015-06-27)

• @Bind replaces @InjectView and @InjectViews.
• ButterKnife.bind and ButterKnife.unbind replaces ButterKnife.inject and ButterKnife.reset, respectively.
• @Optional has been removed. Use @Nullable from the 'support-annotations' library, or any other annotation named "Nullable".
• New: Resource binding annotations!
  • @BindBool binds an R.bool ID to a boolean field.
  • @BindColor binds an R.color ID to an int or ColorStateList field.
  • @BindDimen binds an R.dimen ID to an int (for pixel size) or float (for exact value) field.
  • @BindDrawable binds an R.drawable ID to a Drawable field.
  • @BindInt binds an R.int ID to an int field.
  • @BindString binds an R.string ID to a String field.
• Fix: Missing views will be filtered out from list and array bindings.
• Note: If you are using Proguard, the generated class name has changed from being suffixed with $$ViewInjector to $$ViewBinder.

Version 6.1.0 (2015-01-29)

• New: Support for injecting interface types everywhere that views were previously supported (e.g., Checkable).
• Eliminate reflection-based method invocation for injection and resetting. This makes performance slightly faster (although if you are worried about the performance of Butter Knife you have other problems). The only reflection in the library is a single Class.forName lookup for each type.

Version 6.0.0 (2014-10-27)

• New: Listeners can bind to the root view being injected by omitting a view ID on the annotation.
• New: Exceptions thrown from missing views now include the human-readable ID name (e.g., 'button1').
• Specifying multiple fields binding to the same ID is now considered an error.
• findById overload for view lookup on Dialog instances.
• Experimental: Click listeners are now globally debounced per frame. This means that only a single click will be processed per frame preventing race conditions due to queued input events.
• Experimental: Multiple methods can bind to the same listener provided that listener's callback method does not require a return value.

Version 5.1.2 (2014-08-01)

• Report an error if the annotations are on a class inside the android.* or java.* package. Since we ignore these packages in the runtime, injection would never work.

Version 5.1.1 (2014-06-19)

• Fix: Correct rare ClassCastException when unwinding an InvocationTargetException.

Version 5.1.0 (2014-05-20)

• New listener!
  • View: @OnTouch.
• Fix: @Optional now correctly works for @InjectViews fields.
• Fix: Correct erasure problem which may have prevented the processor from running in Eclipse.

Version 5.0.1 (2014-05-04)

• New: Support Dialog as injection source.
• Fix: Unwrap InvocationTargetException causes for more helpful exceptions.

Version 5.0.0 (2014-04-21)

• New: @InjectViews annotation groups multiple IDs into a List or array.
• New: ButterKnife.apply method applies an Action, Setter, or Android Property to views in a list.
• New listeners!
  • ViewPager: @OnPageChange.
  • AdapterView: @OnItemSelected.
  • TextView: @OnTextChanged.
• New: Multi-method listener support. Specify a callback argument to choose which method the binding is for. (See @OnItemSelected for an example)
• Fix: Support for generic types which are declared with an upper-bound.
• Fix: Use less sophisticated method injection inspection in the annotation processor. The previous method caused problems with some Eclipse configurations.

Version 4.0.1 (2013-11-25)

• Fix: Correct a problem preventing the annotation processor to access Android types when certain javac configurations were used to build.

Version 4.0.0 (2013-11-25)

Views class is now named ButterKnife

• New listeners!
  • View: @OnLongClick and @OnFocusChanged.
  • TextView: @OnEditorAction.
  • AdapterView: @OnItemClick and @OnItemLongClick.
  • CompoundButton: @OnCheckedChanged.
• New: Views are now only checked to be null once if at least one of the fields and/or methods lack the @Optional annotation.
• Fix: Do no emit redundant casts to View for methods.

Version 3.0.1 (2013-11-12)

• Fix: Do not emit redundant casts to View.

Version 3.0.0 (2013-09-10)

• New: Injections are now required. An exception will be thrown if a view is not found. Add @Optional annotation to suppress this verification.

Version 2.0.1 (2013-07-18)

• New: Control debug logging via Views.setDebug.

Version 2.0.0 (2013-07-16)

• New: @OnClick annotation for binding click listeners to methods!

Version 1.4.0 (2013-06-03)

• New: Views.reset for settings injections back to null in a fragment's onDestroyView callback.
• Fix: Support parent class injection when the parent class has generics.

Version 1.3.2 (2013-04-27)

• Multiple injections of the same view ID only require a single find call.
• Fix: Ensure injection happens on classes who do not have any injections but their superclasses do.

Version 1.3.1 (2013-04-12)

• Fix: Parent class inflater resolution now generates correct code.

Version 1.3.0 (2013-03-26)

• New: Injection on objects that have zero @InjectView-annotated fields will no longer throw an exception.

Version 1.2.2 (2013-03-11)

• Fix: Prevent annotations on private classes.

Version 1.2.1 (2013-03-11)

• Fix: Correct generated code for parent class inflation.
• Fix: Allow injection on protected-scoped fields.

Version 1.2.0 (2013-05-07)

• Support injection on any object using an Activity as the view root.
• Support injection on views for their children.
• Fix: Annotation errors now appear on the affected field in IDEs.

Version 1.1.1 (2013-05-06)

• Fix: Verify that the target type extends from View.
• Fix: Correct package name resolution in Eclipse 4.2

Version 1.1.0 (2013-03-05)

• Perform injection on any object by passing a view root.
• Fix: Correct naming of static inner-class injection points.
• Fix: Enforce findById can only be used with child classes of View.

Version 1.0.0 (2013-03-05)

Initial release.
