基于Android物理的平滑变速动画示例代码

import android.animation.ValueAnimator;
import android.view.View;

View object = findViewById(R.id.object);
float initialPosition = 0; // 初始位置
float initialVelocity = 0; // 初始速度

ValueAnimator animator = ValueAnimator.ofFloat(initialPosition, finalPosition);

animator.setInterpolator(new AccelerateDecelerateInterpolator());

animator.setDuration(duration);

animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
    @Override
    public void onAnimationUpdate(ValueAnimator animation) {
        float position = (float) animation.getAnimatedValue();
        object.setTranslationX(position);
    }
});

animator.start();
