RussianIME 全程解析2

1 .If you create one softime,you should extend android .inputmethodservice.InputMethodService，this class provides a basic implemention of softinputmethod.

2 . RussianIME life cycle

 

 

3 Inputmethod UI

 

In the inputmethod,there are two UI styles,softkeyboard and candidate area，that is keyboard view&candidate view.

 

keyboard view： is the place that people input the word,when inputmethod is displayed (when inputmethod display in the forst time),the InputMethodService.onCreateInputView() will be called.

(是用戶輸入文字的地方，當輸入法被顯示的時候(當輸入法第一次展現的時 候)會調用InputMethodService.onCreateInputView().)
Candidates View:is used to provider the input option ,is the place of all the candidate word to display. It can be null,it can return null when call nputMethodService.onCreateCandidatesView().

(是用來提供輸入選擇，是候選詞彙集合出現的地方。其可有可無，可以在調用是候選詞彙集合出現的地方。其可有可無，可以在調用InputMethodService.onCreateCandidatesView時返 回null，–這是它的默認行爲。)
