Below are the helpers that are not part of any specific Anko subsystem.


Using helpers in your project

All helpers are inside the anko-commons artifact. Add it as a dependency to your build.gradle:

dependencies {
    compile "org.jetbrains.anko:anko-commons:$anko_version"


Two simple extension functions to make the code more readable.

You can specify dimension values in dip (density-independent pixels) or in sp (scale-independent pixels): dip(dipValue) or sp(spValue). Note that the textSize property already accepts sp (textSize = 16f). Use px2dip and px2sp to convert backwards.


applyRecursively() applies the lambda expression to the passed View itself, and then recursively to every child of a View if it is a ViewGroup:

verticalLayout {
    editText {
        hint = "Name"
    editText {
        hint = "Password"
}.applyRecursively { view -> when(view) {
    is EditText -> view.textSize = 20f
