示例1: getVisibleChildViews

import android.widget.BaseExpandableListAdapter; //导入方法依赖的package包/类
/**
 * Provides the visible child views.
 * The map key is the group position.
 * The map values are the visible child views.
 *
 * @param expandableListView the listview
 * @param adapter            the linked adapter
 * @return visible views map
 */
public static HashMap<Integer, List<Integer>> getVisibleChildViews(ExpandableListView expandableListView, BaseExpandableListAdapter adapter) {
    HashMap<Integer, List<Integer>> map = new HashMap<>();

    long firstPackedPosition = expandableListView.getExpandableListPosition(expandableListView.getFirstVisiblePosition());

    int firstGroupPosition = ExpandableListView.getPackedPositionGroup(firstPackedPosition);
    int firstChildPosition = ExpandableListView.getPackedPositionChild(firstPackedPosition);

    long lastPackedPosition = expandableListView.getExpandableListPosition(expandableListView.getLastVisiblePosition());

    int lastGroupPosition = ExpandableListView.getPackedPositionGroup(lastPackedPosition);
    int lastChildPosition = ExpandableListView.getPackedPositionChild(lastPackedPosition);

    for (int groupPos = firstGroupPosition; groupPos <= lastGroupPosition; groupPos++) {
        ArrayList<Integer> list = new ArrayList<>();

        int startChildPos = (groupPos == firstGroupPosition) ? firstChildPosition : 0;
        int endChildPos = (groupPos == lastGroupPosition) ? lastChildPosition : adapter.getChildrenCount(groupPos) - 1;

        for (int index = startChildPos; index <= endChildPos; index++) {
            list.add(index);
