我正在对JSONArray进行排序，并在自定义列表视图中显示它们，但排序后，数据在自定义列表视图中不会发生更改

以下是我的代码，用于选择要执行的排序：

fab.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        AlertDialog.Builder builder=new AlertDialog.Builder(SearchResult.this);
        builder.setTitle("Sort List Item");
        builder.setItems(new CharSequence[]{"By Name", "By Father Name","By EPIC","By House Number"}, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {

                switch (i)
                {
                    case 0:
                        Toast.makeText(getApplicationContext(), "By Name", Toast.LENGTH_SHORT).show();

                        sortJsonTechnique="1";
                        if (myData)
                        {
                            sortByName(sortdata,sortJsonTechnique);
                        }
                        break;
                    case 1:

                        Toast.makeText(getApplicationContext(), "By Father Name", Toast.LENGTH_SHORT).show();
                        sortJsonTechnique="2";
                        if (myData)
                        {
                            sortByName(sortdata,sortJsonTechnique);
                        }

                        break;
                    case 2:

                        Toast.makeText(getApplicationContext(), "By EPIC", Toast.LENGTH_SHORT).show();
                        sortJsonTechnique="3";
                        if (myData)
                        {
                            sortByName(sortdata,sortJsonTechnique);
                        }

                        break;
                    case 3:

                        Toast.makeText(getApplicationContext(), "By House Number", Toast.LENGTH_SHORT).show();
                        sortJsonTechnique="4";
                        if (myData)

                        break;
                    default:
                        break;
                }

            }
        });
        builder.show();


    }
});
在fab按钮中进行选择后，单击i sort json数组。 下面是解析json数组的代码：

对于（inti=0；i，在将数据设置为Listview之前，应该使用java中的comparator类对数据进行排序

您可以创建一个模型类，其中包含所需的所有变量（名称、booth_id等），并将每个对象存储到ArrayList中


Collections.sort(ArrayListObject,new NameComparator()); 


范例


class NameComparator implements Comparator{  
public int compare(Object o1,Object o2){  
YourClassName s1=(YourClassName )o1;  
YourClassName s2=(YourClassName )o2;  

return s1.name.compareTo(s2.name);  
}  
}

} 



不要为字段创建一个字符串数组的数据对象，而是为JsonArray的每个元素创建一个对象。
为JsonArray中的对象创建列表。
在自定义适配器中传递该列表。
将listview适配器设置为自定义适配器

现在，只要您想按任何字段对数据进行排序，就可以使用Java collections comparator，您可以编写自己的自定义comparator

之后，只需在适配器上调用notifyDataSetChanged（）

您可以创建模型搜索项，如下所示


class SearchItem {
    private String voterId;
    private String boothNameId;
    private String searchName;
    private String houseNumber;
    private String gender;

    public void setVoterId(String voterId) {
        this.voterId = voterId;
    }

    public String getVoterId() {
        return voterId;
    }

    ......................(Add as many fields you want and their corresponding getter and setter methods)
}


您的Json解析类可以这样修改（您必须填充SearchItem类的所有字段）


class ParseJsonData {

    public static ArrayList<SearchList> parseSearchresult(String jsonResponse) {
        try {
            JSONObject searchData = new JSONObject(jsonResponse);
            JSONArray searchArray=searchData.getJSONArray(SEARCH_VOTER_ARRAY);
            ArrayList<SearchItem> searchList = new ArrayList<SearchItem>();
            for(int index = 0; index < searchArray.length(); index++) {
                JSONObject searchItem = searchArray.get(index);
                SearchItem item = new SearchItem();
                item.setVoterId(searchItem.optString(KEY_VOTER_ID, null);
                item.setBoothNameId(searchItem.optString(KEY_BOOTHNAME_ID, null);
                item.setSearchName(searchItem.optString(KEY_SEARCH_NAME, null);

                item.setGender(searchItem.optString(KEY_SEARCH_GENDER, null);
                searchList.add(item);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return searchList;
    }
}

现在，您可以创建自己的自定义适配器，如下所示


class CustomSearchList extends BaseAdapter {
    ArrayList<SearchItem> mSearchList;
    Context mContext;

    public CustomSearchList(Context context, ArrayList<SearchItem> searchList) {
        mContext = context;
        mSearchList = searchList;
    }

    ..........................(Implement methods for BaseAdapter or other methods you want to write)
}



class CustomSearchList扩展了BaseAdapter{
ArrayList-mSearchList；
语境；
公共CustomSearchList（上下文，ArrayList searchList）{
mContext=上下文；
mSearchList=搜索列表；
}
……………（实现BaseAdapter的方法或要编写的其他方法）
}


这里searchList作为引用传递，所以该列表中的任何更新以及对适配器的notify调用都将反映更改

可以这样修改listview类。parseSearchList（）方法返回所有searchlist的arraylist


private void getList(String json) {
    ArrayList<SearchItem> searchList = ParseJsonData.parseSearchresult(json);
    CustomSearchList adapter = new CustomSearchList(this, searchList);
    searchlistView.setAdapter(adapter);

    mBtn.setOnClickListener(this, new OnClickListener() {
        @Override
        public void onClick(....) {
            //Suppose when some button click happens for sorting
            Collections.sort(searchList, <yourCustomComparator>);
            notifyDataSetChanged();
        }
    });
}



private void getList（字符串json）{
ArrayList searchList=ParseJsonData.parseSearchresult（json）；
CustomSearchList adapter=新的CustomSearchList（此为searchList）；
searchlistView.setAdapter（适配器）；
mBtn.setOnClickListener（这是新的OnClickListener（）{
@凌驾
公共void onClick（..）{
//假设某个按钮点击进行排序
集合。排序（搜索列表，）；
notifyDataSetChanged（）；
}
});
}



最好将searchList设置为成员变量而不是本地变量。
而不是为字段创建一个带有字符串数组的数据对象。为JsonArray的每个元素创建一个对象。
为JsonArray中的对象创建列表。
在自定义适配器中传递该列表。
将listview适配器设置为自定义适配器
