Best practice: Implementing text fields

• Use the TextField class to create text fields. For more information about creating text fields, see the API reference guide

for the BlackBerry® Java® SDK and the BlackBerry Java Application UI Quick Reference Guide.

• Choose a type of text field based on what you expect users to type. Using the most appropriate text field is important so

that the appropriate typing indicator appears on the screen when users type text. For example, when users type text in a

phone number field, the number lock indicator appears in the upper-right corner of the screen. The field that you choose

also affects the default typing input method for the field on BlackBerry devices with SureType® technology.

• Use or extend existing fields instead of creating custom fields where possible so that fields inherit the appropriate default

behavior.

• If necessary, include hint text to provide guidance to users. Use hint text if space on a screen is limited and you cannot

include a label or instructional text. Hint text appears in the field and disappears when users type.

Guidelines for labels

• Use concise, descriptive labels. Avoid labels that wrap.

• Use title case capitalization.

• Punctuate labels for fields with a colon (:).

• If you use hint text, keep it concise. Use sentence case capitalization.

Users can use the search field on the Home screen to search for items in any application on the device, including third-party

applications. The search can also include content that is not stored on the device, such as an organization's database or a web site.

Users can also use a search field in an application to search for items in that application. For example, users can search for an

email message in a message list, a song in the Media application, or a contact in the contact list. In some cases, you might want

to display search results from other applications.
