ObjectAnimator

透明度

alphaanimator = ObjectAnimator.ofFloat(textView, "alpha", 1, 0, 1);

alphaanimator.setDuration(3*1000);

alphaanimator.start();

旋转：

rotationanimator = ObjectAnimator.ofFloat(textView, "rotation", 0, 360, 0);

rotationanimator.setDuration(3*1000);

rotationanimator.start();

大小：

scaleanimator = ObjectAnimator.ofFloat(textView, "scaleX", 0.5f, 1);

scaleanimator.setDuration(3*1000);

scaleanimator.start();

背景色：

bgcoloranimator = ObjectAnimator.ofInt(textView, "BackgroundColor", 0xffff00ff, 0xff00ff22);

bgcoloranimator.setEvaluator(new ArgbEvaluator());

bgcoloranimator.setDuration(3*1000);

bgcoloranimator.start();

XML文件：

ObjectAnimator xmlAnimator = (ObjectAnimator) AnimatorInflater.loadAnimator(ObjectAnimatorActivity.this, R.animator.objectanimator);

xmlAnimator.setTarget(textView);

xmlAnimator.start();

<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"

    android:valueFrom="300"

    android:valueTo="-300"/>
