Question

我的问题是我在Rest Api中有一个名为name的Json对象。登录/注册后，我需要获取它并在我的应用程序中显示textView15字段。我不知道如何获取和显示Json。任何帮助都会很明显。

Api是：

{
  "users": {
    "_id": "gcx8ksa4XepvYRyWH",
    "emails": [
      {
        "address": "selenium@gmail.com",
        "verified": false
      }
    ]
  },
  "user": {
    "_id": "wWHmKn5ciWAHZGt2m",
    "user_id": "gcx8ksa4XepvYRyWH",
    "name": "selenium@gmail.com",
    "hubs": [],
    "username": "selenium",
    "industry": "selenium",
    "profession": "selenium"
  }
}

我的代码：

 AsyncHttpClient client = new AsyncHttpClient();
        applyJobItems.clear();
        List<String> userCredentials = UserUtils.getLoginDetails();
        client.addHeader("x-user-id", userCredentials.get(0));
        client.addHeader("x-auth-token", userCredentials.get(1));
        client.get("https://", new AsyncHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

                final String response = new String(responseBody);
                android.util.Log.e("Response", "" + response);

                try {
                    JSONObject jsonObject = new JSONObject(response);
                    final JSONArray jsonArray = jsonObject.getJSONArray("user");


                    final List<String> names = new ArrayList<String>();
                    for (int i = 0; i < jsonArray.length(); i++) {
                        JSONObject inter = new JSONObject(jsonArray.get(i).toString());
                        ApplyJobItem jobItem = new ApplyJobItem();
                        jobItem.setName(inter.getString("name"));
                        names.add(inter.getString("name"));
                        applyJobItems.add(jobItem);
                        android.util.Log.e("name", inter.getString("name"));
                    }
                }catch (Exception e) {
                        e.printStackTrace();
                    }

Answer 1

将这个json放在android中的JSONObject变量中并像

一样解析它

String name = jsonObject.getJSONObject('user').getString('name');

此处jsonObject是您从服务器获取的主要json对象的名称..

                    adapter.notifyDataSetChanged();

                    listView.setVisibility(View.VISIBLE);

                }
            }, new Response.ErrorListener() {
