Android realizes the jumping ball loading animation effect

Let's take a look at the renderings first

To do this animation, you need to master:

1. Attribute animation

2. Path class, canvas class

3. Bessel curve

4. Surfaceview usage

5. Custom attr attribute

6. Architecture: state mode, controller

7. Concepts of free fall, parabola, etc

I won't say more. Just go straight to the code

1.DancingView. java

2.DancingInterpolator. java

3. Custom attribute styles xml

Note: the color, size and parameters can be tested and adjusted by yourself.

The above is the whole content of this article. I hope it can be helpful to your study and work.
