Zoum Validation

Zoum validation is a standalone library designed to offer a new custom EditText that is validatable, the EditText animates (default is a shake) if its contents is invalid.

Validation occurs using regular expressions, and for your convenience the library provides some validation methods:

• EMAIL Validate emails, someone@domain.topdomain

• NUMBER Validate any integer number

• ALPHABET Accepts alphabetical charcteres from A - Z and from a - z

• ALPHANUMERIC Validates alphabet and numbers

• HEXIDECIMAL_COLOR Validates Hexadecimal colors starting with #, ex. #66EEAB or #777

• URL Validates any URL starting with http, https, or ftp

• NON_EMPTY Accepts any non-empty input

Usage

Validation criteria

Programatically:

By calling the setValidationCriteria(String validation_criteria) with a regular expression. Or by calling the setValidation(Validation validation) with a predefined validation method.

EX: myValidatedEditText.setValidationCriteria("^[0-9]*(1|3|5|7|9)$"); or myValidatedEditText.setValidation(Validation.EMAIL);

From XML:

The criteria can be also set from the XML layout file, but requires the library namespace at your XML is included

at the top node: xmlns:zoum="http://schemas.android.com/apk/res-auto".

Then use this in your layout, note the zoum:custom_criteria attribute.

<com.zoumapps.validated.ValidationEditText
    android:id="@+id/edittext_validate2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:padding="8dp"
    zoum:custom_criteria="^[0-9]*(1|3|5|7|9)$" />

Invalid Input Indicator

Programatically:

By calling the setInvalidInputIndicator(Animation animation). Or by calling the setInvalidInputIndicator(int animation_resource) with the ID to an animation resource.

From XML:

The invalid input animation can also be set in the XML layout file, using the zoum:invalid_input_indicator attribute.

<com.zoumapps.validated.ValidationEditText
    android:id="@+id/edittext_validate2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:padding="8dp"
    zoum:invalid_input_indicator="@anim/my_custom_animation" />

Sanitization

Provides callback to automatically sanitize input text when the user navigates away from the field. Implement ValidatedEditText.OnFixTextListener's onFixText(CharSequence) to return a sanitized version of the given text. Then set this listener with myValidatedEditText.setOnFixTextListener(myOnFixTextListener).
