Android Property Animation 动画有很多大神写过,都非常好,这里只通过ObjectAnimator /ValueAnimator实现上下左右浮动效果。
很简单看代码就好
private void floatAnim(View view,int delay){
List animators = new ArrayList<>();
ObjectAnimator translationXAnim = ObjectAnimator.ofFloat(view, "translationX", -6.0f,6.0f,-6.0f);
translationXAnim.setDuration(1500);
translationXAnim.setRepeatCount(ValueAnimator.INFINITE);//无限循环
translationXAnim.setRepeatMode(ValueAnimator.INFINITE);//
translationXAnim.start();
animators.add(translationXAnim);
ObjectAnimator translationYAnim = ObjectAnimator.ofFloat(view, "translationY", -3.0f,3.0f,-3.0f);
translationYAnim.setDuration(1000);
translationYAnim.setRepeatCount(ValueAnimator.INFINITE);
translationYAnim.setRepeatMode(ValueAnimator.INFINITE);
translationYAnim.start();
animators.add(translationYAnim);
AnimatorSet btnSexAnimatorSet = new AnimatorSet();
btnSexAnimatorSet.playTogether(animators);
btnSexAnimatorSet.setStartDelay(delay);
btnSexAnimatorSet.start();
}
开始设置setRepeatMode(ValueAnimator.INFINITE);方法没有效果,只有设置setRepeatCount(ValueAnimator.INFINITE)才可以。
