食神摇摇中图片的晃动效果

可以是这样子实现滴：

btn_shake=(ImageView)findViewById(R.id.btn_shake);
startShakeAnimation(btn_shake);

private void startShakeAnimation(View v){
		int pivot = Animation.RELATIVE_TO_SELF;
		CycleInterpolator interpolator = new CycleInterpolator(3.0f);
		RotateAnimation animation = new RotateAnimation(0, 15, pivot, 0.5f,pivot, 0.5f);
		animation.setStartOffset(4000);
		animation.setDuration(2000);
		animation.setRepeatCount(Animation.INFINITE);
		animation.setInterpolator(interpolator);
		v.startAnimation(animation);
	 }

知道CycleInterpolator是干嘛用的就简单了，Api demo里有它的用法，是个摇头效果！

抖动:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="180"
    android:fromDegrees="-2"
    android:pivotX="100%"
    android:pivotY="100%"
    android:repeatCount="infinite"
    android:repeatMode="reverse"
    android:toDegrees="2" />

Animation shake = AnimationUtils.loadAnimation(context, R.anim.shake);
shake.reset();
shake.setFillAfter(true);
image.startAnimation(shake);

摇头效果：

代码实现：

/** 
     * 晃动动画 
     * @param counts 1秒钟晃动多少下 
     * @return 
     */  
    public static Animation shakeAnimation(int counts){  
        Animation translateAnimation = new TranslateAnimation(0, 10, 0, 0);  
        translateAnimation.setInterpolator(new CycleInterpolator(counts));  
        translateAnimation.setDuration(1000);  
        return translateAnimation;  
    }
