Abstract


The rapid development of intelligent terminals launched a new social revolution, especially the development of smart phones is changing modern society, people's lifestyles . To Nokia's Symbian, Google 's Android, Microsoft's Windows Mobile as the representative of smart phone operating system is compete in battle, the final winner , began to take shape : Android with its astonishing speed gradually devouring Symbian's market , and is expected to sit market the league title. Currently on the Android platform mobile phone input method focuses yards high prevalence , enter shortcomings of low efficiency . Shantou University, Chen Qin Wu teacher invention of the Digital Chinese character input method can greatly improve this shortcoming . This paper analyzes the Android IMF framework, based on the initial realization of its encoding scheme - strokes coded. This encoding scheme is not only low weight code and coding is simple , easy to learn , easy to use , will greatly enhance the Android platform character information input efficiency. The paper first on the Android platform input method framework including Android IMF framework composition and realization of the principle and Android IME life cycle , analyzed , and then the Android platform provides NDK native code development tools proposed strokes coding scheme on the Android platform to achieve framework - client / server mode (C / S mode ) , the upper application that client uses the Java language to achieve, is responsible for interacting with the user as well as for the entire life cycle of the control input , the underlying service that server efficiency higher C implementation, responsible for the font file search , search results will be sent to the upper application by a candidate for the upper application box displays to the user. Upper application and the underlying interactions between services is achieved through the JNI interface , we have designed a set for the upper application calls the JNI interface , which greatly facilitate code maintenance and the input method on different platforms transplant . Concludes with a discussion of the inadequacies of the present study as well as the outlook for subsequent development .
