最近的一个android 项目中，客户要求在查看拍照上传的图片时，可以对图片进行多点触控的拖拽、放大、缩小等操作。网上的范例都不怎么好，实现的效果差强人意。
下面说说我的方案：
步骤一：自定义一个View，该View继承自ImageView。在该View中实现多点触控的拖拽、缩放等功能。
步骤二：像使用ImageView那样，在XML中引入该View。当然也可以动态创建该View然后添加到容器组件中。-A recent android projects, customer requirements when viewing photos uploaded images, the images can be multi-touch drag, zoom and other operations. The Internet is not a good example of how to achieve the effect of poor.
Here to talk about my plan:
Step one: Customize a View, The View inherited from ImageView. Multi-touch dragging in the View, zoom and other functions.
Step Two: Use ImageView like that, the introduction of the View in XML. Of course, you can dynamically create the View and then added to the container component.
