Android 筛选后ExpandableListView子顺序不正确

嘿，伙计们，这就是我如何在我的可扩展列表中添加内容的

listDataHeader = new ArrayList(Arrays.asList("Afghanistan",
            "Albania",
            "Algeria",
            "Andorra",
            "Angola",
            "Anguilla",
            "Antigua and Barbuda",
            "Argentina",
            "Armenia",
            "Aruba",`........`

listDataChild=新HashMap>（）

有什么帮助吗？

已解决：

设置getChild（）和getChildrenCount（）正确地解决了这个问题

public int getChildrenCount(int groupPosition) {
    return this.filteredDatachild.get(this.filteredData.get(groupPosition))
            .size();
}



public Object getChild(int groupPosition, int childPosititon) {
        return this.filteredDatachild.get(this.filteredData.get(groupPosition))
                .get(childPosititon);
    }

创建新的子列表，如下所示：

for (int i = 0; i < count; i++) {
            filterableString = list.get(i);
            if (filterableString.toLowerCase().contains(filterString)) {
                nlist.add(filterableString);


                nchildlist.put(nlist.get(ii),originalDatachild.get(nlist.get(ii)));
                ii++;
                Log.d( "Child Items:", "Child index:" + ii);
            }

for（int i=0；i

如果订单很重要，请使用LinkedHashMap

listDataChild.put(listDataHeader.get(0), Afghanistan);//Header,Child data
listDataChild.put(listDataHeader.get(1), Albania);
listDataChild.put(listDataHeader.get(2), Algeria);
listDataChild.put(listDataHeader.get(3), Andorra);
listDataChild.put(listDataHeader.get(4), Angola);
listDataChild.put(listDataHeader.get(5), Anguilla);

public int getChildrenCount(int groupPosition) {
    return this.filteredDatachild.get(this.filteredData.get(groupPosition))
            .size();
}



public Object getChild(int groupPosition, int childPosititon) {
        return this.filteredDatachild.get(this.filteredData.get(groupPosition))
                .get(childPosititon);
    }

for (int i = 0; i < count; i++) {
            filterableString = list.get(i);
            if (filterableString.toLowerCase().contains(filterString)) {
                nlist.add(filterableString);


                nchildlist.put(nlist.get(ii),originalDatachild.get(nlist.get(ii)));
                ii++;
                Log.d( "Child Items:", "Child index:" + ii);
            }
