android - 尝试正确提取值但遇到问题

问题描述

我很难让我的代码有效地获取值。

    "Entry": "Value1, Value2, Value3, Value4"
    }
    ]
    }
    }
    }
    }

到目前为止，我已经能够解析大部分数据，但认为有一种更好的方法可以在不获取大量错误信息的情况下提取它。有没有办法通过识别他们的@Type_Id 来解析 Json 数组中的信息？

例如，仅通过查找类型 ID 来返回电话、Twitter URL、网站 URL 和电子邮件？


    private void jsonParse() {

    final String postcode = userPostcode.getText().toString().trim();
    String lookupUrl = "https://example/example/example" + postcode + "example/example/example";
    final String imageURL = "https://example/example/example";

    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, lookupUrl, null,
    new Response.Listener<JSONObject>() {
    @Override
    public void onResponse(JSONObject response) {
    JSONObject members = null;
    try {
    members = response.getJSONObject("Members");
    JSONObject member = members.getJSONObject("Member");
    String firstID = String.valueOf(member.getInt("@First_Id"));
    String areaName = member.getString("MemberFrom");
    String name = member.getString("DisplayAs");
    String partyName = partyOf.getString("#text");
    String mpGender = member.getString("Gender");
    String mpDOB = member.getString("DateOfBirth");
    String mpFrom = member.getString("HouseStartDate");
    String mpImageURL = imageURL + mpID + "/";

    JSONObject partyOf = member.getJSONObject("Party");                     

    JSONObject addresses = member.getJSONObject("Addresses");
    JSONArray addressesArray = addresses.getJSONArray("Address");
    for (int i = 0; i < addressesArray.length(); i++) {
    try {
    JSONObject addressObjects = addressesArray.getJSONObject(i);
    } catch (JSONException e) {
    e.printStackTrace();
    }
    }

    JSONObject primaryPosts = member.getJSONObject("PrimaryPosts");
    JSONArray primaryPostsArray = primaryPosts.getJSONArray("PrimaryPost");
    for (int i = 0; i < primaryPostsArray.length(); i++) {
    try {
    JSONObject primiaryPostObjects = primaryPostsArray.getJSONObject(i);
    } catch (JSONException e) {
    e.printStackTrace();
    }
    }

    JSONObject formerPosts = member.getJSONObject("FormerPosts");
    JSONArray formerPostsArray = formerPosts.getJSONArray("FormerPost");
    for (int i = 0; i < formerPostsArray.length(); i++) {
    try {
    JSONObject formerPostsObject = formerPostsArray.getJSONObject(i);
    } catch (JSONException e) {
    e.printStackTrace();
    }
    }

    JSONObject biographyEntries = member.getJSONObject("BiographyEntries");
    JSONArray BiographyEntriesArray = biographyEntries.getJSONArray("BiographyEntry");
    for (int i = 0; i < BiographyEntriesArray.length(); i++) {
    try {
    JSONObject biographyEntriesPostsObject = BiographyEntriesArray.getJSONObject(i);
    } catch (JSONException e) {
    e.printStackTrace();
    }
    }

    } catch (JSONException e) {
    e.printStackTrace();
    }
    }
    }, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
    Log.d("Error", "onErrorResponse: " + error.getMessage());
    error.printStackTrace();
    }
    }) {
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
    Map<String, String> params = new HashMap<String, String>();
    params.put("Content-Type", "application/json");
    return params;
    }
    };

    mQueue.add(request);
    }
