在 android 中解析来自 PHP Webservice 的响应 - Parse Response from PHP Webservice in android

我正在尝试在android中使用带有JSON的PHP Web服务

我从服务器获得响应数据，因为

string(170) "["14","Samsung","1","15","Nokia","1","16","Sony Ericson","1","18","LG","1","19","Iphone","1","21","HTC","1","22","Motorola","1","23","Micromax","1","41","BlackBerry","1"]"

我应该如何分析它以在 ListView 上显示它。我熟悉如何通过创建自定义适配器在 ListView 上显示数据，但我无法分析此输出。请帮忙

我按照本教程访问了 PHP Web 服务

http://www.codeproject.com/Articles/267023/Send-and-receive-json-between-android-and-php给我一些参考。任何帮助，不胜感激。
谢谢。。。

阿洛斯我想知道在 php 端生成的 JSONArray 的正确格式是什么？

首先它不是有效的 Json 格式，Json 必须有一个label并且value对应的是 "label"： "value"，但您仍然可以手动解析此字符串喜欢这个

String yourString= "["14","Samsung","1","15","Nokia","1","16","Sony Ericson","1","18","LG","1","19","Iphone","1","21","HTC","1","22","Motorola","1","23","Micromax","1","41","BlackBerry","1"]";
yourString= yourString.subString(1, yourString.length()-1);
String[] arrayValue= yourString.split(",");

现在你有arrayValue[0]= "14" arrayValue[1]= "Samsung"等等。

看起来像一个"愚蠢的json"数组。基本上没有问题，因为您将其视为字符串列表。通常我建议使用一些JSON类，但在这种特殊简单的情况下，以下内容就足够了：

String jsonString = "["14","Samsung","1","15","Nokia","1","16","Sony Ericson","1","18","LG","1","19","Iphone","1","21","HTC","1","22","Motorola","1","23","Micromax","1","41","BlackBerry","1"]"
jsonString = jsonString.subString(1, substring.length() -1);
String[] singleValues = jsonString.split(",");

这应该导致这个

new String[]{"14","Samsung","1",....}

您可以在自定义 ListAdapter 中传递该字符串数组（但默认的也应该没问题）

这是有效但奇怪的 json 响应。解析此 json 时，将获得 27 个值。14，三星， 1， 15，诺基亚...但似乎每 3 个项目都是一个对象，例如"14，三星，1"15，诺基亚，1"。而那个json并没有反映这一点。

使用这样的在线 json 解析器，您可以看到您可以看到的结果：

你可以像这样解析这个json：

List<String> list = new ArrayList<String>();
int counter = 0;
boolean first = true;
String json = "['"14'",'"Samsung'",'"1'",'"15'",'"Nokia'",'"1'",'"16'",'"Sony Ericson'",'"1'",'"18'",'"LG'",'"1'",'"19'",'"Iphone'",'"1'",'"21'",'"HTC'",'"1'",'"22'",'"Motorola'",'"1'",'"23'",'"Micromax'",'"1'",'"41'",'"BlackBerry'",'"1'"]";
JSONArray getJSONArray;
try {
  getJSONArray = new JSONArray(json);
  for (int i = 0; i < getJSONArray.length(); i++) {
    Log.d("", getJSONArray.getString(i) + "-" + i % 1 + "-" + i % 2);
    if ((first == true && counter == 1) || (first == false && counter == 2)) {
      list.add(getJSONArray.getString(i));
      counter = 0;
      first = false;
    }
    else {
      counter += 1;
    }
  }
}
catch (JSONException e) {
  e.printStackTrace();
}

记录您的阵列以查看您得到的内容：

for (String item : list) {
  Log.d("list", item);
}

结果：

D/list    ( 1669): Samsung
D/list    ( 1669): Nokia
D/list    ( 1669): Sony Ericson
D/list    ( 1669): LG
D/list    ( 1669): Iphone
D/list    ( 1669): HTC
D/list    ( 1669): Motorola
D/list    ( 1669): Micromax
D/list    ( 1669): BlackBerry

对于服务器站点：

通常，json必须是这样的。

[
    {
        id: "14",
        brand: "Samsung",
        status: "1"
    },
    {
        id: "15",
        brand: "Nokia",
        status: "1"
    },
    {
        id: "16",
        brand: "Sony Ericson",
        status: "1"
    }
]
