Imitation NetEase cloud music player (disk spinning, background blur, etc.)

First look at the effect, csdn git always do not move, do not know why.

Main ideas:

1, in addition to the start/pause, the last song, the next one of these three icons, you see a viewgroup, this viewgroup inside has a round cover, black circle disk, stylus, Gaussian blur background image

2, comments off the disk with the rotation of the effect, the current scheme is not the best, if you want to implement, you can combine the round cover and disk into a picture (preferably in Cicicleimageview this inside). Give a spinning animation. Two animations, two view, frame frequency not so high

3, commented out the previous, the next switch when the animation effect of the gradient, the original image from 1-0, the new figure from 0-1 gradient. In the simulator will be error, mainly because the change ImageView background that line error. No specific reasons are currently known. Looks like a wild pointer to the bottom.

Welcome everyone to optimize, revise the above problem, change well must communicate with me.

Here is the code structure:

Circleimageview: Creating a circular picture

Gaussianblurutil: Gaussian Blur

Musicplayview: Player View

Mainactivity: Main control class

Layout 2, one is the master, the other is the player's view. Look at the Lord's will know the train of thought.

One player, three button

The source of the player, there is a lot of attention code.
