说明：
值动画分：平移动画，旋转动画，缩放动画，透明动画，颜色渐变动画
1）animator.setTarget(mIVHandle); 表示把动画添加到要实现动画的view上面
2) translationX 是view源码里的setTranslationX的translationX部分

1.值动画Activity对象
public class PropertyAnimActivity extends Activity { private ImageView mIVHandle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_properties_anim); mIVHandle = (ImageView) findViewById(R.id.iv_hand); } //位移 public void clickTraslate(View view){ ObjectAnimator animator = ObjectAnimator.ofFloat(mIVHandle, "translationX", 0, 200); animator.setDuration(3000); animator.setRepeatCount(ObjectAnimator.INFINITE); animator.setRepeatMode(ObjectAnimator.REVERSE); animator.start(); } //缩放 public void clickScale(View view){ //mIVHandle.setPivotX(0.5f); //mIVHandle.setPivotY(0.5f); ViewHelper.setPivotX(mIVHandle, 0.5f); ViewHelper.setPivotY(mIVHandle, 0.5f); ObjectAnimator animator = ObjectAnimator.ofFloat(mIVHandle, "scaleX", 0, 2); animator.setDuration(3000); animator.setRepeatCount(ObjectAnimator.INFINITE); animator.setRepeatMode(ObjectAnimator.REVERSE); animator.start(); } //旋转 public void clickRotate(View view){ //ObjectAnimator animator = ObjectAnimator.ofFloat(mIVHandle, "rotationX", 0, 360); ObjectAnimator animator = ObjectAnimator.ofFloat(mIVHandle, "rotation", 0, 360); animator.setDuration(3000); animator.setRepeatCount(ObjectAnimator.INFINITE); animator.setRepeatMode(ObjectAnimator.REVERSE); animator.start(); } //透明 public void clickAlpha(View view){ ObjectAnimator animator = ObjectAnimator.ofFloat(mIVHandle, "alpha", 0, 1); animator.setDuration(3000); animator.setRepeatCount(ObjectAnimator.INFINITE); animator.setRepeatMode(ObjectAnimator.REVERSE); animator.start(); } //集合 public void clickSet(View view){ AnimatorSet set = new AnimatorSet(); ObjectAnimator alpha = ObjectAnimator.ofFloat(mIVHandle, "alpha", 0, 1); ObjectAnimator rotation = ObjectAnimator.ofFloat(mIVHandle, "rotation", 0, 360); ObjectAnimator scale = ObjectAnimator.ofFloat(mIVHandle, "scaleX", 0, 2); //1.按循序播放 set.playSequentially(alpha, rotation, scale); //2.按先后播放 set.play(alpha).after(rotation).before(scale); //3.同时播放 set.playTogether(alpha, rotation, scale); set.setDuration(2000); set.start(); } //color public void clickColor(View view){ //setBackgroundColor ObjectAnimator animator = ObjectAnimator.ofObject(mIVHandle, "backgroundColor", new ArgbEvaluator(), Color.RED, Color.BLUE); animator.setDuration(3000); animator.setRepeatCount(ObjectAnimator.INFINITE); animator.setRepeatMode(ObjectAnimator.REVERSE); animator.start(); } //xml public void clickXml(View view){ Animator animator = AnimatorInflater.loadAnimator(this, R.animator.translator); animator.setTarget(mIVHandle); animator.start(); //AnimatorInflater.loadAnimator(this, R.animator.scale).setTarget(mIVHandle).start(); }}2.布局文件activity_properties_anim.xml
