属性动画

这是属性动画的干货，这是单一动画，

textview = (TextView) findViewById(R.id.textview);
        textview.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(getApplication(), "你点击我了", Toast.LENGTH_SHORT).show();
            }
        });
//ObjectAnimator 是继承自ValueAnimator的，ValueAnimator比较少用
// ObjectAnimator animator = ObjectAnimator.ofFloat(textview,"alpha",1f,0f,1f);//alpha 透明变换 // ObjectAnimator animator = ObjectAnimator.ofFloat(textview,"rotation",0f,360f,);//rotation 360°旋转 float curTranslationY = textview.getTranslationY(); ObjectAnimator animator = ObjectAnimator.ofFloat(textview, "translationY", curTranslationY, 500f); // translationX 水平移动，负值向左，正直向右 translationY 垂直移动，正值向下，负值向上 //ObjectAnimator animator = ObjectAnimator.ofFloat(textview,"scaleX",1f,6f,1f); //scaleY 垂直缩放 scaleX水平缩放  animator.setDuration(3000);//动作完成时间

　　　　//动画播放监听
       /* animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
            @Override
            public void onAnimationUpdate(ValueAnimator valueAnimator) {
                float currentValue = (float) valueAnimator.getAnimatedValue();
                Log.d("TAG", "cuurent value is " + currentValue);
            }
        });*/
        // animator.setStartDelay(5000);//延迟执行
        // animator.setRepeatCount(1);//循环次数
        // animator.setRepeatMode(ValueAnimator.REVERSE);//ValueAnimator.REVERSE倒序播放  ValueAnimator.RESTART重新播放
        animator.start();

 下面再贴上组合动画，组合动画就是生成几个动画之后，把他们按照想要的顺序组合起来播放，靠的是 AnimatorSet

　　　　ObjectAnimator moveIn = ObjectAnimator.ofFloat(textview, "translationX", -500f, 0f);
        ObjectAnimator rotate = ObjectAnimator.ofFloat(textview, "rotation", 0f, 360f);
        ObjectAnimator fadeInOut = ObjectAnimator.ofFloat(textview, "alpha", 1f, 0f, 1f);
        AnimatorSet animSet = new AnimatorSet();
        animSet.play(rotate).with(fadeInOut).after(moveIn);//play是播放，with是同时进行,after是在某个动画执行完之后
        animSet.setDuration(5000);
        animSet.start();
