AbstractMoins main functions include Barcode recognition, Prices comparsion, Product traceability, etc. In the latest version, all these functions can be defined using an XML definition file, moreover, using XML files, those functions can be customized for some companys such as an express company or a manufacturer. The current version of Moin is 3.0, which applicable to Symbian and Windows Mobile. With the development of Android platform, implementing the android version of Moin becomes very necessary, this finally become the source of this article.In previous version of Moin, UI code is written in the source code, most of programmers efforts are used to create the UI, in order to change this situation, Moin 3.0 has been launched. The first goal of Moin 3.0 is to improve the efficiency of creating UI. Moreover, besides the requirement of efficience, Moin has more requirement of scalability, the user interface should be easier to create and modified, and after the release of Moin, programmers should be able to modify user interface with very low cost.This article looks deep into the application of XML on Android platform, after analyse the process of normal UI customization, a method of UI customization on Android platform is proposed. This method provides a UI create layer between UI layer and background data, improves the usability and scalability. Main content of this article are:First, define an XML Definition File for Android platform, use this XML Definition File, the UI creation becomes easier, and the user experience is improved, meanwhile, software cost is lower than before.Second, create an XML file parser, this parser contains three parts: data parse part will parse the file representing the UI, UI create part will create the controls and set their attributes, UI rending part will show the result of data parse part and UI create part.At last, according to the requirement of Moin, a barcode process module is provided which will complete the function of th
