  <p>Is it possible to customize system's input method? Any article to read? What classes to edit? </p>
  
  <p>And actually what I want to modify is the Google's default Chinese Pinyin Input Method, which looks almost the same to the English input keyboard. If you know there was a difference to modify this form the English keyboard, please tell me too.  </p>
  
  <p>Thank you !</p>
