replacementString string: String) -> String?

CapnSpellcheck / BetterForegroundImageView.kt
Last active January 24, 2017 03:24
An ImageView that allows the foreground drawable to be positioned anywhere within the view's bounds by using a floating point range 0 - 1, where 0 means the left/top edge is snug with view's left/top, and 1 means the right/bottom edge is snug with view's right/bottom.. X and Y can be positioned separately.

CapnSpellcheck / DialogListPicker.kt
Last active April 30, 2018 08:09
A class to make simple the use of DialogFragment with AlertDialog. You can set a few properties directly, or provide a delegate and deal with Builder directly. *NEW*: This now supports instance state restoration. Assigning a delegate is now deprecated. Instead, implement a provideDelegate() function. For example, Use ActivityDelegatingDialogFrag…
