Question

我的gridview有问题。我有7列gridview，但当我点击一行上的任何列时，我得到一行中第一项的索引。

例如，当我点击第二行的第三列时，获取索引7，但应该是10.

我为此扩展了BaseAdapter。

    CalendarAdapter adapter = new CalendarAdapter(getActivity(), dateFormat.format(month.getTime()), issues, height, getDays(month));
    gridView.setAdapter(adapter);

    gridView.setOnItemClickListener(calendarItemClickListener);

...

private AdapterView.OnItemClickListener calendarItemClickListener = new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        Log.d(TAG, "onItemClick: " + i); // here is bad index
    }
};

适配器：

public CalendarAdapter(Activity c, String monthCalendar, List<Issue> items, float height, List<Calendar> dates) {
    this.dates = dates;

}

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

@Override
public Object getItem(int position) {
    Log.v(TAG, "Position: " + position + ", " + dateFormat.format(dates.get(position).getTime()));
    return hashMap.get(dateFormat.format(dates.get(position).getTime()));
}

@Override
public boolean isEnabled(int position) {
    return dateFormat.format(dates.get(position).getTime()).contains(month);
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;
    if (convertView == null) {
        LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = vi.inflate(R.layout.item_calendar, null);
        AbsListView.LayoutParams param = new AbsListView.LayoutParams(
                (int) (height / ROW_NUMBER),
                (int) (height / ROW_NUMBER));
        convertView.setLayoutParams(param);

        holder = new ViewHolder();
        holder.dayView = (TextView) convertView.findViewById(R.id.date);
        holder.downloadViewButton = (TextView) convertView.findViewById(R.id.downloadViewButton);
        holder.previewImageView = (ImageView) convertView.findViewById(R.id.preview);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

...

XML

    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:numColumns="7"
        android:verticalSpacing="2dp"
        android:horizontalSpacing="2dp"
        android:stretchMode="columnWidth"
        android:gravity="center" />

知道为什么？
