Android basic animation, code build animation

Using code to build Android basic animations, basic animations have the following:

Alphaanimation: Gradient Transparency Animation

Rotateanimation: Rotate Animation

Scaleanimation: Stretch Animation

Translateanimation: Panning Animations

You can define some commonly used animation effects, or you can customize some animations to set aside the parameters.

You can define some combinations of animation effects, such as: from inside to outside. For the combined animation effect, use the basic animation effect to build up.

Use Animationset to add to this collection, so that the animation inside it works together, you can see the unexpected effect.
