android - 如何在android中从下到上动画 View

Question

我有 listView，我在其中从底部添加项目。我想为添加的项目设置动画， ListView 的其余部分应该向上滑动。动画效果应该是从下往上。我试过翻译动画，但它只滑动添加的项目。谢谢

public static void slideToBottom(View view){
    TranslateAnimation animate = new TranslateAnimation(0,0,0,view.getHeight());
    animate.setDuration(500);
    animate.setFillAfter(true);
    view.startAnimation(animate);
    view.setVisibility(View.GONE);
}

public static void slideToTop(View view){
    TranslateAnimation animate = new TranslateAnimation(0,0,view.getHeight(),0);
    animate.setDuration(500);
    animate.setFillAfter(true);
    view.startAnimation(animate);
    view.setVisibility(View.VISIBLE);
}
