Android listview 行删除动画 [英] Android listview row delete animation
本文介绍了Android listview 行删除动画的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
为列表视图行设置动画的最佳方法是什么?
我一直在尝试类似的东西:
final Animation animation = AnimationUtils.loadAnimation(getActivity(), R.anim.translate_up_fade_anim);动画.setAnimationListener(新动画监听器(){@覆盖公共无效onAnimationStart(动画动画){}@覆盖公共无效onAnimationRepeat(动画动画){}@覆盖公共无效onAnimationEnd(动画动画){dataSource.remove(index);适配器.notifyDataSetChanged();}});view.startAnimation(动画)；但动画并不是我想要的.我想我需要为除已删除的列表视图之外的所有其他列表视图行设置动画，但我愿意接受建议.
解决方案
这是源代码(我猜是 android 4.1).

I keep trying something like:
final Animation animation = AnimationUtils.loadAnimation(getActivity(), R.anim.translate_up_fade_anim);
animation.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
dataSource.remove(index);
adapter.notifyDataSetChanged();
}
});
view.startAnimation(animation);
but the animation isn't exactly what i want. I think i need to animate every other listview row except the deleted one, but i am open to suggestions.

Here's the sourcee code (for android 4.1 i guess).
