Android Background Code settings animation

1. Set Rotation animation

Final rotateanimation animation =new rotateanimation (0f,360f,animation.relative_to_self, 0.5f,animation.relative_to _self,0.5f);

Animation.setinterpolator (New Linearinterpolator ());  The linearinterpolator represents a uniform rate of animation.setduration (3000);//Set animation duration animation.setrepeatcount (animation.infinite); Repeat multiple times, can also use specific number of times ll_earn_circle_bg.startanimation (animation);  LL_EARN_CIRCLE_BG  is a linearlayout control

2. Set displacement animation

/*** Cycletimes The number of repetitions of animation *@paramCycletimes*/     Public voidShakeanimation (intcycletimes) {        if(NULL==mshakeanimation) {mshakeanimation=NewTranslateanimation (0, 10, 0, 0); Mshakeanimation.setinterpolator (NewCycleinterpolator (Cycletimes));//set the speed, cycleinterpolator some sort of mathematical curve, that is, the rate of shaking is curvedMshakeanimation.setduration (1500); Mshakeanimation.setrepeatmode (animation.reverse);//set the reverse direction of execution} tv_curmoney.startanimation (mshakeanimation); Tv_curmoney is a TextView control}

3. Set the Zoom animation

/***         /final scaleanimation animation =new scaleanimation (0.0f, 1.0f, 0.0f, 1.0f, Animation.relative_to_self, 0.5f, animation.relative_to_self, 0.5f);         Animation.setduration (2000); //         Iv_go_rank is a ImageView control

Introduction to Rates:

Defining interpolator in an XML file

Android:interpolator= "@android: Anim/accelerate_interpolator"
Android:shareinterpolator= "true"

So all the animation share a interpolator.

Set the following code in code

Anim.setinterpolator (New Accelerateinterpolator ());

When you pass in new one animationset true, all animation share the interpolator.
