There will be districts for logistic, business, commercial, residential, exhibitions, hospitality, humanitarian and entertainment.” All these will be developed by attracted a lot of local and foreign investors, and will be resulting in natural growth of Gross Domestic Production (GDP) during and after Expo 2020, he added. Infrastructure UAE and Dubai is going to invest heavily on infrastructure ahead of Expo 2020, said Khalid Al Malek, CEO Group of Dubai Properties Group, during the plenary session. He also expected this to enhance growth in other relative sectors, including real estate and construction. According to the latest statistic last year, Al Malek said, construction and infrastructure projects announced and underway in the Gulf Cooperation Council (GCC) countries accounts for $1.9 trillion while UAE’s shares accounts for 49 per cent of the overall projects. “UAE continues to remain the largest projects market, with around $940 billion project that have been under execution,” he added.

以上是我的完整 json数据。我通过编写下面的代码成功地将json数据成功地写入了我的logcat。
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
httpGet.setHeader("Accept", "application/json");
try {
HttpResponse httpResponse = httpClient.execute(httpGet);
StatusLine statusLine = httpResponse.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode != 200) {
Toast.makeText(MainActivity.this, "error" + statusCode,
Toast.LENGTH_SHORT).show();
return null;
}
HttpEntity httpEntity = httpResponse.getEntity();
InputStream inputStream = httpEntity.getContent();
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(inputStream));
StringBuilder stringBuilder = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
stringBuilder.append(line);
}
String jsonData = stringBuilder.toString();
//To display json data in LOGCAT
Log.d("Latest 20 feeds", jsonData);
我的问题是我如何解析数据并在logcat中显示，例如：所有＆＃34; title＆＃34;，＆＃34; body＆＃34;等
答案 0 :(得分：2)
首先，您有无效的JSON数据。我不知道你是如何检查并发现它有效但我发现了很多errors你可以通过粘贴它来检查JSON Validate
我删除了您的一些STRING数据以使其在空间中很好地移除并移除了errors，因此它的外观如下所示

现在它的格式有效，所以你现在需要做的就是......
JSONAarray array = new JSONArray(JsonString);
for(int i=0; i<array.length(); i++){
JSONObject object = array.getJSONObject(i);
String title = object.getString("title");
String body = object.getString("body");
System.out.println("Titlte: " + title);
System.out.println("Body: " + body);
}
答案 1 :(得分：2)
以这种方式动态迭代JSON
创建这些方法
1）
public void parseJson(JSONArray data) {
try {
JSONObject obj = new JSONObject();
obj.put("data", data);
parseJson(obj);
} catch (Exception e) {
e.printStackTrace();
}
}
2）
private void parseJson(JSONObject data) {
if (data != null) {
Iterator<String> it = data.keys();
while (it.hasNext()) {
String key = it.next();
try {
if (data.get(key) instanceof JSONArray) {
JSONArray arry = data.getJSONArray(key);
int size = arry.length();
for (int i = 0; i < size; i++) {
parseJson(arry.getJSONObject(i));
}
} else if (data.get(key) instanceof JSONObject) {
parseJson(data.getJSONObject(key));
} else {
System.out.println(key + " : " + data.getString(key));
}
} catch (Throwable e) {
try {
System.out.println(key + " : " + data.getString(key));
} catch (Exception ee) {
}
e.printStackTrace();
}
}
}
}
如何使用？
String jsonData = stringBuilder.toString();
try {
parseJson(new JSONArray(jsonData));
} catch (Exception e) {
}
答案 2 :(得分：0)
我会确保你得到的json字符串是有效的。当它是有效的JSON时，通过使用随jsonData字符串提供的JSONArray构造函数，您将获得json对象的JSONArray。这是一个完整的例子：
jsonData = "{" + jsonData + "}";
JSONArray json = new JSONArray(jsonData);
我希望您使用的是this JSON库。
从我的调查来看，这是无效的（缺少半列等）。您可以使用this工具验证您的json。
这是一个有效的json字符串：

在您的示例JSONArray中。因此，您可以将其解析为对象数组。简单的方法是使用Gson：
String jsonData = stringBuilder.toString();
Gson gson = new Gson();
MyDataObject [] data = gson.fromJson(jsonData, MyDataObject[].class);
答案 4 :(得分：0)
使用Google GSON lib进行自动解析（只需下载最新版本的GSON jar文件并将其放入libs文件夹中的项目中）：
1）创建描述数据模型的类
public class SomeObjectClass {
@SerializedName("body")
private String mBody;
@SerializedName("created_at")
private String mCreatedAt;
@SerializedName("date_time")
private String mDateTime;
@SerializedName("department")
private String mDepartment;
@SerializedName("id")
private long mId;
@SerializedName("include")
private boolean mInclude;
// another fields here
// some getters if you need it
}
2）创建将json字符串解析为对象列表的方法
public List<SomeObjectClass> parseJson(String jsonArray) {
Type listType = new TypeToken<ArrayList<SomeObjectClass>>() {}.getType();
List<SomeObjectClass> yourClassList = new Gson().fromJson(jsonArray, listType);
return yourClassList;
}
3）解析你的json
List<SomeObjectClass> objects = parseJson(jsonData);
4）迭代它并记录
