Question

我有ListView次，我希望随着时间的推移改变ListItem的颜色，当一天中的小时是早上8或9甚至10时，它会起作用，但随着夜晚的时间增加到5或6，它就会停止工作。他们所有的颜色都和原来一样。这很奇怪。

我知道我的代码检查小时是否已经过去了。这是我的getView()方法。

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

    ViewHolder holder;
    LayoutInflater inflater = activity.getLayoutInflater();

    if (convertView == null) {

        convertView = inflater.inflate(R.layout.list_view_adapter_tab, parent, false);
        holder = new ViewHolder();


        SharedPreferences prefs = convertView.getContext().getSharedPreferences("com.example.edonfreiner.siddur", Context.MODE_PRIVATE);

        if (prefs.getBoolean("isHebrewSet", true)) {
            holder.txtSecond = (TextView) convertView.findViewById(R.id.zman);
            holder.txtFirst = (TextView) convertView.findViewById(R.id.time);


        } else {
            holder.txtFirst = (TextView) convertView.findViewById(R.id.zman);
            holder.txtSecond = (TextView) convertView.findViewById(R.id.time);


        }
        convertView.setTag(holder);


    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    this.convertView = convertView;

    HashMap<String, String> map = list.get(position);
    holder.txtFirst.setText(map.get("First"));
    holder.txtSecond.setText(map.get("Second"));

    convertView.setBackgroundColor(Color.TRANSPARENT);

    RelativeLayout relativeLayout = (RelativeLayout) convertView;
    if (ZmanimListTab.getUpComingZmanPosition() > position) {
        for (int i = 0; i < relativeLayout.getChildCount(); i++) {
            ((TextView) relativeLayout.getChildAt(i)).setTextColor(Color.parseColor("#77FFFFFF"));
        }
    }else{
        for (int i = 0; i < relativeLayout.getChildCount(); i++) {
            ((TextView) relativeLayout.getChildAt(i)).setTextColor(Color.parseColor("#FFFFFF"));
        }
    }

    return relativeLayout;
}

以下是获取更改颜色位置的列表索引的方法：

    private void getNextAvailableZman() throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {

    for (int i = 0; i < listZmanim.length; i++) {
        Date targetDate = ((Date) complexZmanimCalendar.getClass().getMethod((String) listZmanim[i]).invoke(complexZmanimCalendar));
        if (targetDate.after(now)) {
            adapter.notifyDataSetChanged();
            upComingZmanPosition = i;
            return;
        }
    }
    upComingZmanPosition = listZmanim.length;
}

感谢您的帮助！

Listview颜色更改在列表很长时不起作用
