我在 android 应用程序中有一些用于 gridview 的自定义适配器。当我第一次启动应用程序时一切正常，但是当我单击按钮并调用函数 refreshCalendar() 时，适配器“记住”文本属性（字体：BOLD）。我检查（列表）calendarCells 并且没有错误。

public class FCalCellsAdapter extends BaseAdapter{

private static final String TAG = "FCalCellsAdapter";

private Context context;
private LayoutInflater inflater;

private List<FCalCell> calendarCells;

public FCalCellsAdapter(Context context, List<FCalCell> calendarCells){
    this.context = context;
    this.calendarCells = calendarCells;

    this.inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

public void refreshCalendarCells(List<FCalCell> calendarCells){
    this.calendarCells = calendarCells;
}

@Override
public int getCount() {
    return calendarCells.size();
}

@Override
public Object getItem(int position) {
    return calendarCells.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

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

    if(convertView == null){
        holder = new Holder();
        v = inflater.inflate(R.layout.gridview_item_cell, null);

        holder.cellBackground = (ImageView) v.findViewById(R.id.cell_background);
        holder.cellDay = (TextView) v.findViewById(R.id.cell_day);
        holder.cellPeriodDay = (TextView) v.findViewById(R.id.cell_period_day);

        v.setTag(holder);
    }else{
        holder = (Holder) v.getTag();
    }

    if(calendarCells.get(position).getDayType() == FCalCell.DAY_TYPE_ACTIVE_MONTH){
        holder.cellBackground.setBackgroundResource(R.drawable.background_cell_white);
    }else if(calendarCells.get(position).getDayType() == FCalCell.DAY_TYPE_TODAY){
        holder.cellBackground.setBackgroundResource(R.drawable.background_cell_today);
        holder.cellDay.setTypeface(Typeface.DEFAULT_BOLD);
    }else{
        holder.cellBackground.setBackgroundResource(R.drawable.background_cell_gray);
    }

    holder.cellDay.setText(calendarCells.get(position).getNumberOfDay());
    holder.cellPeriodDay.setText(String.valueOf(calendarCells.get(position).getPeriodDayNumber()));

    return v;
}

private class Holder{
    private ImageView cellBackground;
    private TextView cellDay;
    private TextView cellPeriodDay;
}

}

refreshCalendar（主要活动）

public void refreshCalendar(){
    List<FCalCell> calendarCells = FCal.getListOfCalendarCells(actualMonth,this);
    adapter.refreshCalendarCells(calendarCells);
    adapter.notifyDataSetChanged();
}

您需要dayCell在 if else 语句中设置所有情况下的字体。s将TextView被重用，他们会记得加粗。如果您的表格变得比屏幕上的大小更大以便可以滚动，您将遇到同样的问题。

像这样的东西：

if(calendarCells.get(position).getDayType() == FCalCell.DAY_TYPE_ACTIVE_MONTH){
    holder.cellBackground.setBackgroundResource(R.drawable.background_cell_white);
    holder.cellDay.setTypeface(Typeface.DEFAULT);
}else if(calendarCells.get(position).getDayType() == FCalCell.DAY_TYPE_TODAY){
    holder.cellBackground.setBackgroundResource(R.drawable.background_cell_today);
    holder.cellDay.setTypeface(Typeface.DEFAULT_BOLD);
}else{
    holder.cellBackground.setBackgroundResource(R.drawable.background_cell_gray);
    holder.cellDay.setTypeface(Typeface.DEFAULT);
}
