关于子线程渲染动画-RenderThread

在这之前，请了解RenderThread——RenderThread基础知识

不知为何，我模拟不出上面博文的效果，特发出来，求助各路大神。

package com.example.zxtext.util;
/*
* RenderThread异步渲染动画实践
* 目前得知目前支持RenderThread完全渲染的动画，只有两种：
* ViewPropertyAnimator和CircularReveal（揭露动画）。
* 而对于CircularReveal（揭露动画）使用比较简单且功能较为单一。

Activity部分代码：

 findViewById(R.id.one1).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Log.d("TAG","one1Click");
                startAnim1(view);
                delaySleep(1000,3000);
                Log.d("TAG","1000one1Click");
            }
        });
        findViewById(R.id.one2).setOnClickListener(new View.OnClickListener() {

                Log.d("TAG","1000one2Click");
            }
        });

    }

    private void startAnim2(View v) {
        v.setScaleY(1);
        ViewPropertyAnimator animator = v.animate().scaleY(2).setDuration(2000);
        AnimHelper.onStartBeforeConfig(animator, v);
        animator.start();
    }

    private void startAnim1(View v) {
        ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(v, "scaleY", 1, 2);
        objectAnimator.setDuration(2000);
        objectAnimator.start();
    }

    private void delaySleep(long delay, final long duration) {
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                try {
                    Thread.sleep(duration);

        }, delay);
