Android 通过Animate硬编码实现简单的平移、旋转、缩放及透明度动画过程

以下只列出主要代码：

[java]
private ImageView scanLight;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        scanLight = (ImageView)findViewById(R.id.img);

        Button translateStart = (Button)findViewById(R.id.translateStart);
        Button translateEnd = (Button)findViewById(R.id.translateEnd);
        Button scaleStart = (Button)findViewById(R.id.scaleStart);
        Button scaleEnd = (Button)findViewById(R.id.scaleEnd);
        Button alphaStart = (Button)findViewById(R.id.alphaStart);
        Button alphaEnd = (Button)findViewById(R.id.alphaEnd);
        Button rotateStart = (Button)findViewById(R.id.rotateStart);
        Button rotateEnd = (Button)findViewById(R.id.rotateEnd);

        translateStart.setOnClickListener(listener);
        translateEnd.setOnClickListener(listener);
        scaleStart.setOnClickListener(listener);
        scaleEnd.setOnClickListener(listener);
        alphaStart.setOnClickListener(listener);
        alphaEnd.setOnClickListener(listener);
        rotateStart.setOnClickListener(listener);
        rotateEnd.setOnClickListener(listener);
    }

    private OnClickListener listener = new OnClickListener()
    {

        @Override
        public void onClick(View v)
        {
            switch (v.getId())
            {
            //平移 setFillAfter(true) 控制执行动画后定在当前状态
            case R.id.translateStart:
                Animation translateIn = new TranslateAnimation(0, 100, 0, 0);
                translateIn.setDuration(500);
                translateIn.setFillAfter(true);
                scanLight.startAnimation(translateIn);
                break;
            case R.id.translateEnd:
                Animation translateOut = new TranslateAnimation(100, 0, 0, 0);
                translateOut.setDuration(500);
                translateOut.setFillAfter(true);
                scanLight.startAnimation(translateOut);
                break;
            //缩放后四个参数控制沿自身中心点缩放
            case R.id.scaleStart:
                Animation sIn = new ScaleAnimation(1f, 2f, 1f, 2f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
                sIn.setDuration(500);
                sIn.setFillAfter(true);
                scanLight.startAnimation(sIn);
                break;
            case R.id.scaleEnd:
                Animation sOut = new ScaleAnimation(2f, 1f, 2f, 1f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
                sOut.setDuration(500);
                sOut.setFillAfter(true);
                scanLight.startAnimation(sOut);
                break;
            //透明度
            case R.id.alphaStart:
                Animation aIn = new AlphaAnimation(1f, 0f);
                aIn.setDuration(500);
                aIn.setFillAfter(true);
                scanLight.startAnimation(aIn);
                break;
            case R.id.alphaEnd:
                Animation aOut = new AlphaAnimation(0f, 1f);
                aOut.setDuration(500);
                aOut.setFillAfter(true);
                scanLight.startAnimation(aO
