The Design And Implementation Of Chinese Input Method On Android

With the widespread use of mobile devices and increasing popularity of short message, microblogging and other mobile applications, the requirement of inputting and processing text information, especially the Chinese information for us, on mobile devices is recreasing rapidly.Firstly, this desertation describes the main component and system framework of Andriod, and then analyzes the advantages and disadvantages of the popular Chinese input methods on all kinds of mobile platforms.Secondly, it uses CKC input method as a sample to describe the design of the relation table between codes and their Chinese characters or phrases and the retrieval method on the Android platform, including the structure of the relation table, the indexing, the association functions, the storage of the relation table, and specific retrieval processes of the input method.Finally, it analyzes the input method framework on the Android platform and gives a detailed exposition of the framework components, circuit, life cycle and some of the necessary achieved classes, functions, and so on. On this basis, it designes and realizes the CKC input method on the Andriod platform, and introduces its implemention technology.Tests on the CKC input system on the Android platform show that our system has reached a very practical level and it already has been used on some extent.
