【问题讨论】：

你尝试了什么？到目前为止？
您解析它的方式与任何其他 JSON 相同
如果您是 JSON 新手，对解析感到困惑，请先将 JSON 内容粘贴到 JSON 查看器中并仔细观察，然后通过了解数据结构得到您需要的答案。在 JSON 中实际上没有什么难的，只有两种类型，一种是 ARRAy，可以作为具有像 a[0] 之类索引的普通数组访问，另一种是 OBJECT，其属性可以使用 '.'(dot); 访问。如果你这样练习，你将很容易解析任何复杂的 JSON。

【解决方案1】：

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");
}

【解决方案2】：

说“数据”是您的 JSON 字符串的名称，那么就可以了（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，您可以通过遍历 JSONArray 并调用 ambulance.getJSONObject(i) 来访问特定对象。然后你只需要调用 getString("ID") 等等来获取值。

【解决方案3】：

您需要按照 json 保持正确的数据结构。

在你的情况下是这样的：

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);
