下面列出了怎么用android.support.v4.view.ViewPropertyAnimatorUpdateListener的API类实例代码及写法，或者点击链接到github查看源代码。
public void createAnimatorTranslationY(final View v, final float h, final FrameLayout fl) {
ViewPropertyAnimatorCompat viewPropertyAnimatorCompat = ViewCompat.animate(v);
viewPropertyAnimatorCompat.setDuration(250);
viewPropertyAnimatorCompat.setInterpolator(new DecelerateInterpolator());
viewPropertyAnimatorCompat.translationY(h);
viewPropertyAnimatorCompat.start();
viewPropertyAnimatorCompat.setUpdateListener(new ViewPropertyAnimatorUpdateListener() {
@Override
public void onAnimationUpdate(View view) {
float height = ViewCompat.getTranslationY(v);
fl.getLayoutParams().height = (int) height;
fl.requestLayout();
}
});
}
public void createAnimatorTranslationY(final View v, final float h, final FrameLayout fl) {
ViewPropertyAnimatorCompat viewPropertyAnimatorCompat = ViewCompat.animate(v);
viewPropertyAnimatorCompat.setDuration(250);
viewPropertyAnimatorCompat.setInterpolator(new DecelerateInterpolator());
viewPropertyAnimatorCompat.translationY(h);
viewPropertyAnimatorCompat.start();
viewPropertyAnimatorCompat.setUpdateListener(new ViewPropertyAnimatorUpdateListener() {
@Override
public void onAnimationUpdate(View view) {
float height = ViewCompat.getTranslationY(v);
fl.getLayoutParams().height = (int) height;
