说＆＃34;数据＆＃34;是你的JSON字符串的名称，然后这样做（不要忘记捕获JSONException）：
JSONObject dataJson = new JSONObject(data).getJSONObject("data");
JSONArray ambulance = dataJson.getJSONArray("ambulance");
JSONArray bloodbank = dataJson.getJSONArray("bloodbank");
JSONArray hospital = dataJson.getJSONArray("hospital");
例如，您可以通过迭代JSONArrays并调用ambulance.getJSONObject（i）来访问特定对象。然后你只需要调用getString（＆＃34; ID＆＃34;）等等来获取值。
答案 1 :(得分：0)
您需要按照json保持正确的数据结构。
在你的情况下：
public class Response{
public List<Ambulance> aList = new ArrayList<Ambulance>();
public List<BloodBank> bList = new ArrayList<Ambulance>();
//getter setter for both lists
}
public class Ambulance{
private String ID = "";
private String Title = "";
private Double Longitude=0.0;
private Double Latitude=0.0;
private String Address = "";
public String getID() {
return ID;
}
public void setID(String iD) {
ID = iD;
}
public String getTitle() {
return Title;
}
public void setTitle(String title) {
Title = title;
}
public Double getLongitude() {
return Longitude;
}
public void setLongitude(Double longitude) {
Longitude = longitude;
}
public Double getLatitude() {
return Latitude;
}
public void setLatitude(Double latitude) {
Latitude = latitude;
}
public String getAddress() {
return Address;
}
public void setAddress(String address) {
Address = address;
}
}
public class BloodBank{
private String ID = "";
private String Title = "";
private Double Longitude=0.0;
private Double Latitude=0.0;
private String Address = "";
public String getID() {
return ID;
}
public void setID(String iD) {
ID = iD;
}
public String getTitle() {
return Title;
}
public void setTitle(String title) {
Title = title;
}
public Double getLongitude() {
return Longitude;
}
public void setLongitude(Double longitude) {
Longitude = longitude;
}
public Double getLatitude() {
return Latitude;
}
public void setLatitude(Double latitude) {
Latitude = latitude;
}
public String getAddress() {
return Address;
}
public void setAddress(String address) {
Address = address;
}
}
然后解析为：
Response response = new Gson().fromJson(responseString,
Response.class);

使用 this link 和doInBackground方法，您必须拥有以下代码：
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONObject data = jsonObj.getJSONObject("data");
// Getting JSON Array node
JSONArray ambulance = jsonObj.getJSONArray("ambulance");
// looping through All ambulance
for (int i = 0; i < ambulance.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
String id = c.getString("ID");
String Title = c.getString("Title");
String Longitude = c.getString("Longitude");
String Latitude = c.getString("Latitude");
String Address = c.getString("Address");
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
