摘　　要：屏幕触摸是移动设备上最主要的交互方式,为了实现该方式,开发者需要基于基本的onTouchEvent等事件机制编写响应逻辑。安卓官方支持库提供了对触摸事件进行封装的控件。对于不熟悉支持库特性的开发者,将已有代码替换为支持库控件的实现需要一定的学习代价。针对以上需求,提出一种面向触控类支持库的应用代码替换技术。对可替换的目标代码,分别从功能实现、监听器绑定和资源文件这三个方面生成替换建议。实验结果表明,该技术能针对与支持库控件相应的,用基本触控逻辑实现的事件回调方法及其资源布局给出替换建议。Screen touch is the most important interaction mode on mobile devices.In order to implement this method,developers need to write response logic based on basic event mechanism such as onTouchEvent.Android official support libraries provide controls to encapsulate touch events.However,for Android junior developers who are not familiar with the various support libraries,replacing existing code with a support library requires a certain learning cost.In response to the above requirements,this paper proposes a code replacement technique for Android touch-class support library.For replaceable object code,replacement suggestions are generated from three aspects:function implementation,listener binding and resource file.The experimental results show that the proposed technique can give replacement suggestions for the event callback method and resource layout corresponding to the support library widgets.
