Android的JSON响应键值，解析 [英] android json response key value, parsing

问题描述

我从一个Web服务的JSON响应：

i get a JSON response from a web service:

{"CoverageSearchByLatLongResult":{"HasTransmissionAreasWithSignal":true,"SwitchOffArea": 
{"OpenForVastApplications":false,"SeperateTileSetUrl":"http:\/\/myswitch.merged.stage.orchard.net.au\/geodatafiles\/SwitchOffArea\/442b8844-3c05-4548-9424-
 4fdafc1f3c62\/Seperate","HASStatus":"Future","HASStatement":"<p>The Household Assistance Scheme is not yet available in this switchover area. Eligible households will be sent a letter when the scheme opens in the Sydney area.<\/p>","SwitchOffDate":"31 December 2013","Events":{"MaximumProximity":6.864859435168742,"Items":[{"Name":"Test Event","Time":"Time","Url":"","Date":"Date","Address":"19a Boundary Street, Rushcutter...

所以我的问题是，在android系统的Java如何索要键：CoverageSearchByLatLongResult

so my question is, in android java how to ask for the key: CoverageSearchByLatLongResult

在ObjC在iphone，是这样的：

in ObjC in iphone , something like this:

  NSDictionary *coverageResult = [response objectForKey:@"CoverageSearchByLatLongResult"];

所以基本上即时解析用钥匙一本字典，但结果我需要把它的其他的字典里面，

so basically im parsing a dictionary with a key, but that result i need to put it inside other dictionary,

[如有错误纠正我，java中词典被称为地图？]

[correct me if wrong, in java dictionaries are called maps?]

如何做到这一点？

非常感谢！

推荐答案

您应在org.json包中的类：

You should use the classes in the org.json package:

http://developer.android.com/reference/org/ JSON /包summary.html

有了他们，你可以做这样的事情：

With them you can do things like:

try {
    String jsonString = "YOUR JSON CONTENT";
    JSONObject obj = new JSONObject(jsonString);
    JSONObject anotherObj = obj.getJSONObject("CoverageSearchByLatLongResult");
    boolean bool = anotherObj.getBoolean("HasTransmissionAreasWithSignal");

    JSONArray jsonArray = obj.getJSONArray("arrayKey");
    int i = jsonArray.getInt(0);
} catch (JSONException e) {
    e.printStackTrace();
}

Java的地图地图键的值。由于其使用的例子：

Java Maps map keys to values. As an example of their use:

Map<String, Integer> map = new HashMap<String, Integer>();
map.put("string key", 1);
map.put("another key", 3);
