Android Json解析服务器文件

给你我的一个代码片段,自己去理解吧

解析代码:

解析json数据

@param context

源数据

/

private void parseJson(String json)

{

try

{

JSONArray json_1 = new JSONArray(json);

List<Course> list = new ArrayList<Course>();

for (int i = 0; i < json_1length(); i++)

{

JSONObject json_2 = json_1getJSONObject(i);

Systemoutprintln("第一层第" + (i + 1) + "条数据="

+ json_2getString("Name") + "ID："

+ json_2getInt("ID") + "父级ID："

+ json_2getInt("ParentID"));

parese(json_2);//TODO

JSONArray json_3 = json_2getJSONArray("Children");

if (json_3length() != 0)

{

for (int j2 = 0; j2 < json_3length(); j2++)

{

JSONObject json_4 = json_3getJSONObject(j2);

Systemoutprintln("第二层第" + (i + 1) + "条数据="

+ json_4getString("Name") + "ID："

+ json_4getInt("ID") + "父级ID："

+ json_4getInt("ParentID"));

JSONArray json_5 = json_4getJSONArray("Children");

if (json_5length() != 0)

{

for (int k = 0; k < json_5length(); k++)

{

JSONObject json_6 = json_5getJSONObject(k);

Systemoutprintln("第三层第" + k + "条数据"

+ json_6getString("Name") + "ID："

+ json_6getInt("ID") + "父级ID："

+ json_6getInt("ParentID"));

}

}

}

}

}

}

catch (JSONException e)

{

eprintStackTrace();

}

}

数据源:

public class Cosnt

{

public static final String SOURCE = "[{Name:语言知识与语言运用,ID:7332,Children:[{Name:字音,ID:7333,Children:[{Name:字音,ID:7334,Children:[],ParentID:7333}],ParentID:7332},{Name:字形,ID:7339,Children:[],ParentID:7332},{Name:词语,ID:7345,Children:[],ParentID:7332},{Name:句子,ID:7375,Children:[],ParentID:7332},{Name:标点符号,ID:7381,Children:[],ParentID:7332},{Name:修辞,ID:7387,Children:[],ParentID:7332},{Name:语言运用与语言表达,ID:7390,Children:[],ParentID:7332}],ParentID:0},"

+ "{Name:文化、文学常识和名篇名句,ID:7405,Children:[{Name:作家作品,ID:7406,Children:[],ParentID:7405},{Name:古代文化常识,ID:7428,Children:[],ParentID:7405},{Name:名篇名句,ID:7431,Children:[],ParentID:7405}],ParentID:0},"

+ "{Name:文言文,ID :7434,Children:[{Name:文言实词,ID:7435,Children:[],ParentID:7434},{Name:文言虚词,ID:7439,Children:[],ParentID:7434},{Name:文言句式,ID:7442,Children:[],ParentID:7434},{Name:文言文阅读,ID:7445,Children:[],ParentID:7434}],ParentID:0}]";

}

看别人使用的类：主要用到的类有：orgapachehttpclientHttpClient 、orgapachehttpclientmethodsHttpPost 和orgjsonJSONObject，应该包含这个方法的
