Example 6 with LongSparseArray

use of android.support.v4.util.LongSparseArray in project SeriesGuide by UweTrottmann.

the class CalendarAdapter method generateHeaderList.

protected List<HeaderData> generateHeaderList() {
    int count = getCount();
    if (count == 0 || !mIsShowingHeaders) {
        return null;
    }
    // pre-size to 30 as we display 30 days == headers at most
    LongSparseArray<HeaderData> mapping = new LongSparseArray<>(30);
    List<HeaderData> headers = new ArrayList<>();
    for (int position = 0; position < count; position++) {
        long headerId = getHeaderId(position);
        HeaderData headerData = mapping.get(headerId);
        if (headerData == null) {
            headerData = new HeaderData(position);
            headers.add(headerData);
        }
        headerData.incrementCount();
        mapping.put(headerId, headerData);
    }
    return headers;
