Maskara

A simple way to format text fields without getting affected by input filters.

How It Works

Mask

Used to define how to format the text.

  • value is used to define the format string. E.g. +90 (___) ___ __ __

There's no limitation here. You can use any type of characters with any type of input filters.

  • maskCharacter is used to define which characters in the format string user can edit. E.g. _

It's not mandatory to define this explicitly. Mask will set the character with most occurences in the format string as maskCharacter by default.

You should use non alphanumeric characters here.

MaskStyle

Used to define mask visibility and cursor behaviour.

  • Normal Mask is never visible. Cursor is not limited.

  • Completable Mask becomes visible right after the user started typing until the user deleted everything. Cursor is not limited.

  • Persistent Mask becomes visible right after the user started typing and never becomes hidden. Cursor is limited between mask characters.

MaskResult

You can retrieve these from both the widget and the listener.

  • masked Masked version of input text.

  • unMasked Raw version of input text.

  • isDone Validity of input text.

Usage

With Widget

<com.santalu.maskara.widget.MaskEditText
    android:id="@+id/input"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="number"
    app:mask="+90 (___) ___ __ __"
    app:maskCharacter="_"
    app:maskStyle="completable" />

To get the result:

val masked = input.masked
val raw = input.unMasked
val isDone = input.isDone

Without Widget

val mask = Mask(
    value = "+90 (___) ___ __ __",
    character = '_',
    style = MaskStyle.COMPLETABLE
)
val listener = MaskChangedListener(mask)
textField.addTextChangedListener(listener)

To get the result:

val masked = listener.masked
val raw = listener.unMasked
val isDone = listener.isDone
