    Quick Start: Display C1MaskedTextField Controls
    In This Topic

    This section describes adding C1MaskedTextField controls to an Android application for specifying four input fields, namely ID, Date of Birth, Phone and State. The ID input field accepts a nine-digit number separated by hyphens, the Date of Birth field accepts a date in mm/dd/yyyy format, the Phone field accepts a 10-digit number with area code, and the State field accepts abbreviated postal code of a state.

    The following image shows the input fields after completing the above steps.

    Add the following code to initialize four input fields using C1MaskedTextField controls in you .axml file.
