Anroid简单属性动画

Android提供了几种动画类型：View Animation 、Drawable Animation 、Property Animation 。View Animation相当简单，不过只能支持简单的缩放、平移、旋转、透明度基本的动画，且有一定的局限性。

下面是属性动画的几种基础效果

//平移

    public void translationAnimRun( View view) {
        ObjectAnimator.ofFloat(view, "translationX", 0.0F, 200.0F)
                // 设置执行时间(1000ms)
                .setDuration(1000)
                // 开始动画
                .start();
    }
    //旋转
    public void rotateyAnimRun( View view)
    {
        ObjectAnimator//
                .ofFloat(id_bull, "rotationX", 0.0F, 360.0F)//
                .setDuration(500)//
                .start();
    }
    //渐变
    public void AlphaAnimRun(final View view)
    {
        ObjectAnimator anim = ObjectAnimator//
                .ofFloat(view, "zhy", 1.0F,  0.0F)//
                .setDuration(500);//
        anim.start();
        anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener()
        {
            @Override
            public void onAnimationUpdate(ValueAnimator animation)
            {
                float cVal = (Float) animation.getAnimatedValue();
                view.setAlpha(cVal);
                view.setScaleX(cVal);
                view.setScaleY(cVal);
            }
        });
    }
    //集合
    public void propertyValuesHolder(View view)
    {
        PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat("alpha", 1f,
                0f, 1f);
        PropertyValuesHolder pvhY = PropertyValuesHolder.ofFloat("scaleX", 1f,
                0, 1f);
        PropertyValuesHolder pvhZ = PropertyValuesHolder.ofFloat("scaleY", 1f,
                0, 1f);
        ObjectAnimator.ofPropertyValuesHolder(view, pvhX, pvhY,pvhZ).setDuration(1000).start();

    }
