Listview项目滚动时动画停止

Question

我试图ProgressBar用每个ListView项目的简单动画显示,但是当我滚动时,ProgressBar动画停止.滚动结束后,动画再次开始.见下图.

Answer 1

你必须在getView()中使用动画并为convertView示例设置动画:

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    ViewHolder holder;

    StructureArticles item = getItem(position);
    if (convertView == null) {
        convertView = G.inflater.inflate(R.layout.adapter_articles, parent, false);
        holder = new ViewHolder(convertView);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.fill(this, item, position);
    Animation animationListView = AnimationUtils.loadAnimation(context, R.anim.scale_fade_in);
    convertView.startAnimation(animationListView);

    return convertView;
}

Answer 2

我在我的适配器中使用了这个语法并且问题解决了!

public class AdapterDownload extends ArrayAdapter<StructDownload> {

public AdapterDownload(ArrayList<StructDownload> array) {
    super(G.context, R.layout.item_layout, array);
}


private static class ViewHolder {

    public ViewHolder(View view)
    {

    }


    public void fill(final ArrayAdapter<StructDownload> adapter, final StructDownload item, final int position)
    {

    }
}


@Override
public View getView(int position, View convertView, ViewGroup parent) {

}

}

谢谢.
