在这里就贴一个方法吧！！！！！！！！！！！！！哪里需要直接引用就行


private void initAnimator() {
    //透明  从有到无在到有
    ObjectAnimator alpha = ObjectAnimator.ofFloat(mTxtView, "alpha", 1f, 0f, 1f);
    //X轴翻转
    ObjectAnimator rotationX = ObjectAnimator.ofFloat(mTxtView, "rotationX",  0f, 360f);
    //X轴缩放
    ObjectAnimator scaleX = ObjectAnimator.ofFloat(mTxtView, "scaleX", 1f, 3f, 1f);
    //Y轴缩放
    ObjectAnimator scaleY = ObjectAnimator.ofFloat(mTxtView, "scaleY", 1f, 3f, 1f);
    //创建AnimatorSet实例
    AnimatorSet animatorSet = new AnimatorSet();
    //动画运行时间
    animatorSet.setDuration(1500);
    //大家一起来
    animatorSet.playSequentially(rotationX,scaleX,scaleY,alpha);
    animatorSet.start();
    //动画监听事件
    animatorSet.addListener(new Animator.AnimatorListener() {
        @Override
        public void onAnimationStart(Animator animator) {

        }

        @Override
        public void onAnimationEnd(Animator animator) {
            //动画结束时跳转
            startActivity(new Intent(WelcomeActivity.this,MainActivity.class));
            finish();
        }

        @Override
        public void onAnimationCancel(Animator animator) {

        }

        @Override
        public void onAnimationRepeat(Animator animator) {

        }
    });

}
