问题描述

谁能告诉我怎么做创造这种观点的转变?我试过 opengl ，但我没有帮助，而且我不懂螃蟹！

someone can tell me how to create this transformation of view ? I tried opengl , but I was not helping and I did not understand crabs!

推荐答案

It's done using a BitmapMesh canvas.drawBitmapMesh(..);这基本上是一个坐标网格.查看 Api 演示中的 BitmapMesh.java 以获取简单示例.

It´s done using a BitmapMesh canvas.drawBitmapMesh(..); which basically is a grid of coordinates. Check out BitmapMesh.java in the Api demos for a simple example.

然后使用 PathMeasure 将坐标映射到一组路径以实现波浪效果.希望以后有时间写一篇博文，开源窗帘菜单.

The coordinates are then mapped up to a set of Paths using PathMeasure to achieve the wavy effect. I hope to get the time to write a blogpost and opensource the curtainmenu in the future.
