示例1: findCurrentSectionPosition

import android.widget.SectionIndexer; //導入依賴的package包/類
int findCurrentSectionPosition(int fromPosition) {
	ListAdapter adapter = getAdapter();

	if (fromPosition >= adapter.getCount()) return -1; // dataset has changed, no candidate

	if (adapter instanceof SectionIndexer) {
		// try fast way by asking section indexer
		SectionIndexer indexer = (SectionIndexer) adapter;
		int sectionPosition = indexer.getSectionForPosition(fromPosition);
		int itemPosition = indexer.getPositionForSection(sectionPosition);
		int typeView = adapter.getItemViewType(itemPosition);
		if (isItemViewTypePinned(adapter, typeView)) {
			return itemPosition;
		} // else, no luck
	}

	// try slow way by looking through to the next section item above
