示例1: getDisappearAnimator
import com.nineoldandroids.animation.ObjectAnimator; //導入方法依賴的package包/類
public ObjectAnimator getDisappearAnimator() {
if (!mIsInitialized || !mDrawValuesReady) {
Log.e(TAG, "RadialSelectorView was not ready for animation.");
return null;
}

float midwayPoint = 0.2f;
int duration = 500;
kf0 = Keyframe.ofFloat(0f, 1);
kf1 = Keyframe.ofFloat(midwayPoint, mTransitionMidRadiusMultiplier);
kf2 = Keyframe.ofFloat(1f, mTransitionEndRadiusMultiplier);

示例2: getReappearAnimator
import com.nineoldandroids.animation.ObjectAnimator; //導入方法依賴的package包/類

// staggered against the disappear so they happen seamlessly. The reappear starts
// halfway into the disappear.
