BaseExpandableListAdapter中 添加下面代码 可以解决 原理不太清楚 就记录一下.

@Override
public long getGroupId(int groupPosition) {
    return groupPosition;
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return getCombinedChildId(groupPosition, childPosition);
}

@Override
public long getCombinedChildId(long groupId, long childId) {
    return super.getCombinedChildId(groupId, childId);
}
