推荐答案
您需要绘制自定义组件看到这个页面了解更多信息：
You would need to draw a custom component see this page for more information:
http://developer.android.com/guide/topics/ UI /自定义components.html 。
您将需要重写绘制方法和绘制自己的列表视图，以及你曾经从拖动物品的位置。这是一个复杂的任务，可能会令人望而生畏，但我真的没有见过有人做一拖之前的Android下降。您可能是第一个！
You would need to override the draw method and draw your own list view as well as where ever your dragging your items from. This is a complicated task and may seem daunting but I haven't really seen anyone do a drag and drop on android before. You may be the first!
