PatternedEditText

PatternedEditText is an EditText that shows its text according to a pattern.

If you want your EditText to show its text with slight modifications as the user inputs, you need to implement a TextWatcher.

With using default EditTexts, you'd probably need to implement different TextWatchers for different input types.

PatternedEditText provides you a simple way to achieve this with a pattern of your need.

For instance,

• "#### #### #### ####" as Credit Card Numbers,
• "(###)-(### ## ##)" as Phone Numbers,
• "##/##/####" as Dates etc.

Usage

Define your PatternedEditText in your layout.

<com.faradaj.patternededittext.PatternedEditText
            xmlns:pet="http://schemas.android.com/apk/res-auto"
            android:id="@+id/edit_text_phone_number"
            pet:pattern="(###)-(### ## ##)"
            pet:specialChar="#"     <!-- optional, # by default -->
            pet:showHint="true"     <!-- optional, false by default -->
            android:inputType="number"
            android:digits="0123456789 ()-"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

pet:pattern: This is your pattern definition, you need to define one. pet:specialChar: This is the special character that you use in your pattern to indicate user-input characters. If you don't define one '#' character is used. pet:showHint: If you set this true, your pattern is used as hint, overriding EditTexts android:hint.

Important Points

• You need to use getRawText() method when you need your PatternedEditTexts raw text.

• You need to add necessary digits to android:digits of PatternedEditText. For instance, phone number may only need numbers so you had defined android:inputType="number" previously. And if your pattern pet:pattern="(###)-(### ## ##)" includes custom characters, now you need to define android:digits="0123456789 ()-" too.
