[英]How to use RenderScript with SurfaceView/View
Latest Android SDK (R22) has removed android.renderscript.RSSurfaceView
and android.renderscript.RenderScriptGL
classes. 最新的Android SDK(R22)已删除
android.renderscript.RSSurfaceView
和android.renderscript.RenderScriptGL
类。 How can we use RenderScript dirrectly on SurfaceView or regular Android View? 我们如何在SurfaceView或常规Android View上直接使用RenderScript?
Short answer: It's complicated. 简短回答:这很复杂。
Long answer: https://github.com/googlesamples/android-HdrViewfinder 答案很长: https : //github.com/googlesamples/android-HdrViewfinder
They seem to make an RGBA allocation: 他们似乎做了一个RGBA分配:
Type.Builder rgbTypeBuilder = new Type.Builder(rs, Element.RGBA_8888(rs));
rgbTypeBuilder.setX(dimensions.getWidth());
rgbTypeBuilder.setY(dimensions.getHeight());
mOutputAllocation = Allocation.createTyped(rs, rgbTypeBuilder.create(),
Allocation.USAGE_IO_OUTPUT | Allocation.USAGE_SCRIPT);
Then get a surface from a SurfaceView holder to pass to the allocation. 然后从SurfaceView持有者获取一个曲面以传递给分配。 Then they run some rs on it, and then call:
然后他们在上面运行一些rs,然后调用:
mOutputAllocation.ioSend();
for each frame... Check the code, seems there are some pitfalls there. 对于每一帧...检查代码,似乎有一些陷阱。
