属性动画注意点
- ofFloat等参数注意点
ObjectAnimator xiaoAniator = ObjectAnimator.ofFloat(llXiao, "translationX", 400f);
equals to
ObjectAnimator xiaoAniator = ObjectAnimator.ofFloat(llXiao, "translationX", 0,400f);
- Animator的start方法，应该在Animator的addListener之后调用
//
ObjectAnimator xiaoAniator = ObjectAnimator.ofFloat(llXiao, "translationX", 400f,0);
xiaoAniator.setInterpolator(new AccelerateDecelerateInterpolator());
xiaoAniator.setDuration(500);
// 公共的 PropertyValuesHolder
PropertyValuesHolder holder_scaleX = PropertyValuesHolder.ofFloat("scaleX", 10f, 1f);
PropertyValuesHolder holder_scaleY = PropertyValuesHolder.ofFloat("scaleY", 10f, 1f);
PropertyValuesHolder holder_alpha = PropertyValuesHolder.ofFloat("alpha", 0.5f, 1f);
// yellow point ,400ms
PropertyValuesHolder yellowHolder_translateX = PropertyValuesHolder.ofFloat("translationX", 2000f,0);
PropertyValuesHolder yellowHolder_translateY = PropertyValuesHolder.ofFloat("translationY", -3000f,0);
final ObjectAnimator yellowAnimator = ObjectAnimator.ofPropertyValuesHolder(ivYellowView, holder_scaleX,
holder_scaleY, yellowHolder_translateX, yellowHolder_translateY, holder_alpha);
yellowAnimator.setDuration(400);
// green point, 400ms
PropertyValuesHolder greenHolder_translateX = PropertyValuesHolder.ofFloat("translationX", 1000f,0);
PropertyValuesHolder greenHolder_translateY = PropertyValuesHolder.ofFloat("translationY", 1500f,0);

holder_scaleY, greenHolder_translateX, greenHolder_translateY, holder_alpha);
greenAnimator.setStartDelay(100);
greenAnimator.setDuration(400);
// blue point,400ms
PropertyValuesHolder blueHolder_translateX = PropertyValuesHolder.ofFloat("translationX", -2000f,0);
PropertyValuesHolder blueHolder_translateY = PropertyValuesHolder.ofFloat("translationY", -2000f,0);

holder_scaleY, blueHolder_translateX, blueHolder_translateY, holder_alpha);
blueAnimator.setStartDelay(200);
blueAnimator.setDuration(400);
// Slogan,400ms
PropertyValuesHolder sloganHolder_scaleX = PropertyValuesHolder.ofFloat("scaleX", 5f, 1f);
PropertyValuesHolder sloganHolder_scaleY = PropertyValuesHolder.ofFloat("scaleY", 5f, 1f);
PropertyValuesHolder sloganHolder_translateX = PropertyValuesHolder.ofInt("translationX", -2000);
final ObjectAnimator sloganAnimator = ObjectAnimator.ofPropertyValuesHolder(ivSlogan, sloganHolder_scaleX,
sloganHolder_scaleY, sloganHolder_translateX);
