android - 如何在一个 View 中收集具有相同值的json，在另一个 View 中收集其他值并制作动态 View

Question

我有下面的 json :

 {  
"transaksi": {
        "jenis_link": "unit_link",
        "rks_ulink": [
            {
                "lji_invest": "Excellink Dynamic Fund",
                "tgl": "22/05/2013",
                "harga_unit": "3,581.38",
                "nilai": "0.000",
                "total_unit": "0.0000"
            },
            {
                "lji_invest": "Excellink Aggressive Fund",
                "tgl": "22/05/2013",
                "harga_unit": "3,758.73",
                "nilai": "35,737,078.757",
                "total_unit": "9,507.7435"
            }
        ],
"ulink": [
            {
                "jumlah_unit": 46.9545,
                "investasi": "Excellink Aggressive Fund",
                "harga_unit": 2041.807,
                "tgl_nab": "25/07/2007",
                "transaksi": "Alokasi Investasi",
                "jumlah": 95872
            },
            {
                "jumlah_unit": 54.722,
                "investasi": "Excellink Aggressive Fund",
                "harga_unit": 1827.417,
                "tgl_nab": "27/08/2007",
                "transaksi": "Alokasi Investasi",
                "jumlah": 100000
            },
            {
                "jumlah_unit": -2.2826,
                "investasi": "Excellink Aggressive Fund",
                "harga_unit": 1857.119,
                "tgl_nab": "17/09/2007",
                "transaksi": "Penarikan-Potongan Aug 07",
                "jumlah": 4239
            },

            {
                "jumlah_unit": 186.3333,
                "investasi": "Excellink Dynamic Fund",
                "harga_unit": 2146.691,
                "tgl_nab": "25/10/2007",
                "transaksi": "Alokasi Investasi",
                "jumlah": 400000
            },
            {
                "jumlah_unit": -7.5143,
                "investasi": "Excellink Dynamic Fund",
                "harga_unit": 2185.977,
                "tgl_nab": "01/11/2007",
                "transaksi": "Penarikan-Potongan Oct 07",
                "jumlah": 16426
            },
            {
                "jumlah_unit": 186.2001,
                "investasi": "Excellink Dynamic Fund",
                "harga_unit": 2148.226,
                "tgl_nab": "26/11/2007",
                "transaksi": "Alokasi Investasi",
                "jumlah": 400000
            },
            {
                "jumlah_unit": -7.5314,
                "investasi": "Excellink Dynamic Fund",
                "harga_unit": 2183.127,
                "tgl_nab": "03/12/2007",
                "transaksi": "Penarikan-Potongan Nov 07",
                "jumlah": 16442
            },
            {
                "jumlah_unit": 183.0457,
                "investasi": "Excellink Dynamic Fund",
                "harga_unit": 2185.247,
                "tgl_nab": "26/12/2007",
                "transaksi": "Alokasi Investasi",
                "jumlah": 400000
            }        ]
    }
}

如您所见，很少有 json "investasi" 值与 "Excellink Dynamic Fund" 相同，而其他值与 "Excellink Aggressive Fund" 相同.我想收集它基于一个 json json "investasi" 具有相同的值，但我的问题是我不知道如何在一个 View 中收集它而在其他 View 中收集其他 View 。有关详细信息，我附上两张图片:

json "investasi" 值与 "Excellink Dynamic Fund" 相同

在这个 View 下是 json "investasi" 值与 "Excellink Aggressive Fund" 相同

到目前为止我做了两个布局，第一个布局包含 ListView :

这就是我解析 json 的方式:

      JSONObject jsonObject = new JSONObject(result);

                            JSONObject transaksi = jsonObject.getJSONObject("transaksi");
                            for (int i=0; i<transaksi.length();i++){
                            String jenis_link = transaksi.getString("jenis_link");

RingkasanUlinkVariabel VarRKS = null;
                            JSONArray rks_ulink = transaksi.getJSONArray("rks_ulink");
                            for (int j=0; j<rks_ulink.length();j++){
                                JSONObject rks = rks_ulink.getJSONObject(j);
                                VarRKS= new RingkasanUlinkVariabel(rks.optString("lji_invest"),
                                        rks.optString("total_unit"),
                                        rks.optString("harga_unit"),
                                        rks.optString("nilai"),
                                        rks.optString("tgl"));
                                ListRingkasan.add(VarRKS);
                                System.out.println("Adam levine");

                            }
                                UnitLinkVariabel VarUnit = null;
                            JSONArray ulink = transaksi.getJSONArray("ulink");
                            for (int k=0; k<ulink.length();k++){
                            JSONObject unit = ulink.getJSONObject(k);
                            VarUnit= new UnitLinkVariabel(unit.optString("investasi"),
                                    unit.optString("transaksi"),
                                    unit.optString("jumlah"),
                                    unit.optString("tgl_nab"),
                                    unit.optString("jumlah_unit"),
                                    unit.optString("harga_unit"));
                            ListUnitLink.add(VarUnit);

那么如何在一个 View 中收集具有相同值的 json 而在另一个 View 中收集其他值并在一个布局中制作动态 View ？我希望有人能帮我解决我的问题

Answer 1

试试这个:

//Declare a different list for containing the UnitLinkVariabel
//one for the "Aggressive" and one for the "Dynamic"
List ListUnitLinkEAF = new ArrayList<UnitLinkVariabel>();
List ListUnitLinkEDF = new ArrayList<UnitLinkVariabel>();

//Declare the handler for each UnitLinkVariabel, 
//again, one for Aggressive, one for Dynamic
UnitLinkVariabel VarUnitEAF = null;
UnitLinkVariabel VarUnitEDF = null;

在:

   for (int k=0; k<ulink.length();k++){
         JSONObject unit = ulink.getJSONObject(k);

添加这样的支票:

         if (unit.optString("investasi").equals("Excellink Aggressive Fund") {
             VarUnitEAF = new UnitLinkVariabel(unit.optString("transaksi"),
                          unit.optString("jumlah"),
                          unit.optString("tgl"),
                          unit.optString("jumlah_unit"),
                          unit.optString("harga_unit"));
             ListUnitLinkEAF.add(VarUnitEAF);
         } else if (unit.optString("investasi").equals("Excellink Dynamic Fund") {
             VarUnitEDF = new UnitLinkVariabel(unit.optString("transaksi"),
                          unit.optString("jumlah"),
                          unit.optString("tgl"),
                          unit.optString("jumlah_unit"),
                          unit.optString("harga_unit"));
             ListUnitLinkEDF.add(VarUnitEDF);
         }

现在你有 2 个列表，一个带有 Excellink Aggressive Fund or (EAF) , 和一个 Excellink Dynamic Fund or (EDF)

你现在需要做的是将每一个列表放到ListView中，如果你想让它们都显示，准备2个listviews，一个用于EAF，一个用于EDF。我将留给您将数据插入 listView。

祝你好运:)

编辑

使用Set<String>获取 Investasi 的值, 阅读 UnitLinkVariabel 的所有条目, 并将所有字符串放在 Investasi 中在Set里面.

如您所知，Set不能有重复项，所以这就是您要查找的内容。

这是一些 fragment :

//Declare the set
Set<String> investasi = new LinkedHashSet<String>();

现在，阅读所有 Investasi并将其添加到 investasi

   for (int k=0; k<ulink.length();k++){
         JSONObject unit = ulink.getJSONObject(k);
         investasi.add(unit.optString("investasi"));
    }

然后，对于每个 investasi ，做点什么:

for (String jenisInvestasi : investasi) {
     for (int k=0; k<ulink.length();k++){
         JSONObject unit = ulink.getJSONObject(k);
         if (unit.optString("investasi").equals(jenisInvestasi)) {
            //insert into list
         }
}

这就是逻辑，你应该可以自己找到其余的代码，祝你好运:D
