如何从NDK中的SurfaceTexture获取ANativeWindow

Question

我有一些OpenGL ES代码已经渲染到了GLSurfaceView,我正在修改它以使用SurfaceView和TextureView.

我在本机代码中需要的共同元素是:ANativeWindow.

因为SurfaceView我通过传递Surface到:

m_jwindow = ANativeWindow_fromSurface(env, surface);

对于TextureView,我接受SurfaceTexture,在API 14中,我可以使用:

m_jwindow = ANativeWindow_fromSurfaceTexture(env, surface);

但是,在Jellybean中删除了该功能.我想留下,我怎样才能ANativeWindow从SurfaceTexture在API 16+？

Answer 1

你需要在API 16+中做的是创建一个Surface对象,将SurfaceTexture作为参数传递给构造函数(在API 14中引入).ANativeWindow_fromSurface()像往常一样将Surface传递给它.
