Generated implicit conversions and extension functions for the Android framework in Scala
All interfaces and abstract classes with a single abstract method have been wrapped by an implicit conversion for the corresponding function.
On top of that, all methods that take these objects as a single parameter have been enhanced to take an automatically typed function or by-name parameter.
The extension functions are named with any prefixed set and suffixed
Listener names removed. Additionally, the remainder of the name is
decapitalized. For example setOnClickListener becomes onClick and
setInterpolator becomes interpolator.
When there are are callbacks with arguments that can be ignored, one can
invoke the 0 variant of the extension function, such as onClick0 to pass
a => A by-name parameter
1.3+: If there is a naming collision in an existing method name, such as
with TextView.onEditorAction, the asScala extension function will wrap
the object with the extension wrapper, and it can be called without
encountering the naming conflict. e.g.
textview.asScala.onEditorAction((a,b,c) => true); this has no allocation
cost.
Base android framework extensions:
libraryDependencies += "com.hanhuy.android" %% "scala-conversions" % "23.1.1"
Extensions for support-v4:
libraryDependencies += "com.hanhuy.android" %% "scala-conversions-v4" % "23.1.1"
Extensions for appcompat-v7:
libraryDependencies += "com.hanhuy.android" %% "scala-conversions-appcompat" % "23.1.1"
Extensions for design:
libraryDependencies += "com.hanhuy.android" %% "scala-conversions-design" % "23.1.1"
Versions will generally track supportSdkVersion numbers, suffixed with letters to represent local fixes. Other versions can be generated upon request.
import com.hanhuy.android.extensions._
findViewById(R.id.something).onClick { v => Toast.makeText(...).show() }
or
findViewById(R.id.something).onClick0 { Toast.makeText(...).show() }
support-v4:
import com.hanhuy.android.v4.extensions._
import com.hanhuy.android.v4.conversions._
appcompat-v7:
import com.hanhuy.android.appcompat.extensions._
import com.hanhuy.android.appcompat.conversions._
design:
import com.hanhuy.android.design.extensions._

From 1.2 onward, generated sources are published to sonatype and browsable
