android animitor(二)

1、平移

ObjectAnimator anim = (ObjectAnimator) AnimatorInflater.
                        loadAnimator(appContext, R.anim.object_animator);
                anim.addUpdateListener(this);
                anim.setTarget(balls.get(0));

xml

 <objectAnimator xmlns:android=""
    android:duration="1000"
    android:valueTo="200"
    android:valueType="floatType"
    android:propertyName="y"
    android:repeatCount="1"
    android:repeatMode="reverse"/>

2、透明度

 ValueAnimator fader = (ValueAnimator) AnimatorInflater.
                        loadAnimator(appContext, R.anim.animator);
                fader.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                    public void onAnimationUpdate(ValueAnimator animation) {
                        balls.get(1).setAlpha((Float) animation.getAnimatedValue());
                    }
                });

xml

<animator xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:valueFrom="1"
    android:valueTo="0"
    android:valueType="floatType"
    android:repeatCount="1"
    android:repeatMode="reverse"/>

3、动画集

AnimatorSet seq =
                 (AnimatorSet) AnimatorInflater.loadAnimator(appContext,
                        R.anim.animator_set);
                seq.setTarget(balls.get(2));

xml

<set>
    <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="1000"
        android:valueTo="200"
        android:valueType="floatType"
        android:propertyName="x"
        android:repeatCount="1"
        android:repeatMode="reverse"/>
    <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="1000"
        android:valueTo="400"
        android:valueType="floatType"
        android:propertyName="y"
        android:repeatCount="1"
        android:repeatMode="reverse"/>
</set>

4、颜色渐变

 ObjectAnimator colorizer = (ObjectAnimator) AnimatorInflater.
                        loadAnimator(appContext, R.anim.color_animator);
                colorizer.setTarget(balls.get(3));

xml

<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:valueFrom="#0f0"
    android:valueTo="#00ffff"
    android:propertyName="color"
    android:repeatCount="1"
    android:repeatMode="reverse"/>

5、播放动画

 animation = new AnimatorSet();
                ((AnimatorSet) animation).playTogether(anim, fader, seq, colorizer);
animation.start();
