问题 I\'ve been trying to create a custom view which has blurred shapes under text. The problem is that the BlurMaskFilter has no effect on any shape that I draw on the canvas.

To be clear, I don\'t want that slider or anything, just the effect of being able to see through the window and having that slight shadow around the edges. I

问题 I\'ve been searching the past three days for a built-in, hardware-accelerated way of bluring a bitmap with android.
