Android属性动画爬坑

属性动画注意点

1. ofFloat等参数注意点

ObjectAnimator xiaoAniator = ObjectAnimator.ofFloat(llXiao, "translationX", 400f);
equals to 
ObjectAnimator xiaoAniator = ObjectAnimator.ofFloat(llXiao, "translationX", 0,400f);

2. 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);
final ObjectAnimator greenAnimator = ObjectAnimator.ofPropertyValuesHolder(ivGreenView, holder_scaleX,
        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);
final ObjectAnimator blueAnimator = ObjectAnimator.ofPropertyValuesHolder(ivBlueView, holder_scaleX,
        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);
sloganAnimator.setDuration(400);

/**
 * startAnimator
 */
xiaoAniator.addListener(new AnimatorListenerAdapter() {

    @Override
    public void onAnimationStart(Animator animation) {
        llXiao.setVisibility(View.VISIBLE);
    }

    @Override
    public void onAnimationEnd(Animator animation) {
        greenAnimator.addListener(new AnimatorListenerAdapter() {

            @Override
            public void onAnimationEnd(Animator animation) {
                ivSlogan.setVisibility(View.VISIBLE);
                sloganAnimator.start();
            }
        });

        sloganAnimator.addListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationEnd(Animator animation) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        runJob(new VersionCheckJob(PackageUtils.getVersionName(context)));
                    }
                }, 300);
                notAnimation = false;
            }
        });
        
        yellowAnimator.addListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationStart(Animator animation) {
                ivYellowView.setVisibility(View.VISIBLE);
            }
        });
        
        blueAnimator.addListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationStart(Animator animation) {
                ivBlueView.setVisibility(View.VISIBLE);
            }
        });
        
        greenAnimator.addListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationStart(Animator animation) {
                ivGreenView.setVisibility(View.VISIBLE);
            }
        });
        
        yellowAnimator.start();
        greenAnimator.start();
        blueAnimator.start();
    }

});
xiaoAniator.start();
