android实现控件抖动，晃动，闪烁，高亮等动画效果实现。
1. 抖动：
/**
* view抖动
* @param iv
*/
@RequiresApi(api = Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public static void viewShaking(View iv){
ObjectAnimator animator = SeekAttentionView.tada(iv);
animator.setRepeatCount(ValueAnimator.INFINITE);
animator.start();
}2.晃动：
/**
* view晃动
* @param iv
*/
@RequiresApi(api = Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public static void viewSloshing(View iv){
ObjectAnimator nopeAnimator = SeekAttentionView.nope(iv);
nopeAnimator.setRepeatCount(ValueAnimator.INFINITE);
nopeAnimator.start();
}其中 SeekAttentionView 是自定义类：
/**
* 对控件的抖动
* 对view的x轴和y轴进行0.9倍到1.1倍的缩放，同时对view进行一定角度的上下旋转。
* Created by Administrator on 2017/11/13 0013.
*/
public class SeekAttentionView {
@RequiresApi(api = Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public static ObjectAnimator tada(View view) {
return tada(view, 1f);
}
/**
* 控件抖动的方法
* @param view
* @param shakeFactor
* @return
*/
@RequiresApi(api = Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public static ObjectAnimator tada(View view, float shakeFactor) {
PropertyValuesHolder pvhScaleX = PropertyValuesHolder.ofKeyframe(View.SCALE_X,
Keyframe.ofFloat(0f, 1f),
Keyframe.ofFloat(.1f, .9f),

Keyframe.ofFloat(.1f, -3f * shakeFactor),
Keyframe.ofFloat(.2f, -3f * shakeFactor),
Keyframe.ofFloat(.3f, 3f * shakeFactor),
Keyframe.ofFloat(.4f, -3f * shakeFactor),
Keyframe.ofFloat(.5f, 3f * shakeFactor),
Keyframe.ofFloat(.6f, -3f * shakeFactor),
Keyframe.ofFloat(.7f, 3f * shakeFactor),
Keyframe.ofFloat(.8f, -3f * shakeFactor),
Keyframe.ofFloat(.9f, 3f * shakeFactor),
Keyframe.ofFloat(1f, 0)
);
return ObjectAnimator.ofPropertyValuesHolder(view, pvhScaleX, pvhScaleY, pvhRotate).
setDuration(1000);

/**

* @param view
* @return
*/

} 3.闪烁
