In android, the effects of edge Blur are implemented through BlurMaskFilter, which defines an edge Blur radius and Blur effect (Blur ).

Blur has four Blur effects: inner, normal, outer, and solid. The following describes the effects:

1. Blur. Inner: The target edge is Inner, And the Blur radius is R. If R> the target width, the excess part is not displayed.

2. Blur. Normal: Blur both inside and outside the target edge, and the radius is R. After blurring, the width and length of the target are increased-the length is R + R.

3. Blur. Outer: Blur the distance from the target edge to the R radius without drawing the target.

4. Blur. Solid: Draw the target and Blur the distance from the target edge to the radius of R.
