Digital Circuit Virtual Laboratory Development ：Android Mobile Result Display System
Abstract: Digital circuits and related experiments occupy an very important position in computer using and educating. Lacking of virtual laboratories, environment, equipment and other aspects is a big problems. So we bring up an idea----develop a virtual laboratory.Nowadays,one of the most important experiment methods is Virtual Laboratory. Saving resources, easy to manage, ideal environment to develop virtual laboratory equipment has become popular. This paper describes the development based on Android technology digital circuit virtual laboratory equipment. The main function is to complete the most basic digital circuit about four experiments:half adder experiment, full adder experiment,encoder test and digital selector experiment.All experiments has their own experimental interface and data display.This design is writted by Java programming language, using Eclipse as Android application development environment.LinearLayout and RelativeLayout layout is used to design the UI screen .All the same, use advanced components Spinner to complete the following selection box.Design an event listener to the button so it can do real action when we click the botton,.Combined with digital circuit principle complete the development of the digital circuit virtual experiments Android mobile applications.
