过滤后,Android Custom ArrayAdapter不会刷新

arrayAdapter.notifyDataSetChanged();

listView.setAdapter(arrayAdapter);

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder viewHolder;
    if (convertView == null) {
        convertView = LayoutInflater.from(context).inflate(R.layout.item_layout, parent, false);
        viewHolder = new ViewHolder();
        viewHolder.textView = convertView.findViewById(R.id.text_view);
        convertView.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }
    viewHolder.textView.setText(getItem(position));
    return convertView;
}

static class ViewHolder {
    TextView textView;
}

new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
        arrayAdapter.notifyDataSetChanged();
        listView.setAdapter(arrayAdapter);
    }
});
