Input type for input fields

The input type for input fields rule ensures that each input field specifies the kind of information the user is expected to enter. Assigning accurate input types, such as email, phone number, or password, helps users quickly understand what they must enter in a particular field. Defining input types also supports assistive technologies in communicating the purpose of each field. Additionally, defining input types improves user experience by optimizing virtual keyboard usability and enhancing screen reader support.

Success Criteria

The specific criteria for success are:

• Input elements are focusable using a screen reader.
• Each input field is assigned an accurate input type.

How to Fix?

• On Android, set the android:inputType field for each input field based on the expected user input.

Example

The following example scan report shows an input type violation in the app’s interface. The issue is identified for the Alternate Email input field.

Error:

• The inputType does not match the inputLabel. Input types define the kind of information a user should enter in an input field. It should also match the input label accurately to avoid confusion. In this example, the input type is TYPE_CLASS_PHONE, which does not match the input label, Alternate Email.

How to fix:

• To fix the violation:
  • Change the input type from TYPE_CLASS_PHONE to TYPE_TEXT_VARIATION_EMAIL_ADDRESS. This accurately conveys the expected input.
