问题描述
问候，
我想放置图像在一个surfaceview。不过，我想图像是透明的，所以你可以看到图像，也是undlying surfaceview。任何人都可以建议我怎么能做到这一点？
I would like to place an image over a surfaceview. However I would like the image to be transparent so you can see the image and also the undlying surfaceview. Can anyone suggest how I could do this?
推荐答案
这是我画的形状之前，我是怎么做的。
This is how I do it before drawing my shapes.
Bitmap buffer = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_4444);
buffer.eraseColor(Color.TRANSPARENT);
