iTAP 

Intelligent Keypad Text Entry API 

When users are using features such as SMS (short message service), or “Text 
Messaging”, they can opt for a predictive text entry method from the handset. The J2ME 
environment has the ability to use SMS in its API listing.  The use of a predictive entry 
method is a compelling feature to the MIDlet. 
This API will enable a developer to access iTAP, Numeric, Symbol and Browse text entry 
methods. With previous J2ME products, the only method available was the standard use 
of TAP. 
Predictive text entry allows a user to simply type in the letters of a word using only one 
key press per letter, as apposed to the TAP method that can require as many as four or 
more key presses. The use of the iTAP method can greatly decrease text-entry time. Its 
use extends beyond SMS text messaging, but into other functions such as phonebook 
entries. 
The following J2ME text input components will support iTAP. 

ƒ  javax.microedition.lcdui.TextBox 

The 

TextBox

 class is a Screen that allows the user to edit and enter text.  

ƒ  javax.microedition.lcdui.TextField 

A 

TextField

 is an editable text component that will be placed into a 

Form

. It is 

given a piece of text that is used as the initial value. 

 
Refer to the Table 20 for iTAP feature/class support for MIDP 2.0: 

Predictive text capability will be offered  when the constraint is set to ANY 

User will be able to change the text input method during the input process when the constraint is set to 
ANY (if predictive text is available) 

Multi-tap input will be offered when the constraint on the text input is set to EMAILADDR, PASSWORD, or 
URL
