Unable to populate AutocompleteTextview with unnamed JSON Array in Android

问题

以下是翻译好的部分：

我一直在尝试使用 API 将自动完成文本视图（autocompletetextview）填充到 JSON 中，但由于 JSON API 没有一个数组名称，所以它无法正常工作。如果我尝试使用其他具有数组名称的 API，它就可以正常工作。

这是 API 的示例链接：link。

我尝试过实现 此答案，但它并没有起作用。

这是 API 的结构。

这是我的方法。

  1. private void populateEduList() {
  2.     List<String> responseList = new ArrayList<>();
  3.     String url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
  4.     JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, response -> {
  6.         try {
  7.             JSONArray jsonArray = new JSONArray(response);
  8.             for (int i = 0; i < jsonArray.length(); i++){
  9.                 JSONObject object = jsonArray.getJSONObject(i);
  10.                 responseList.add(object.getString("name"));
  11.                 ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
  12.                 mAutoCompEdu.setAdapter(adapter);
  13.             }
  14.         } catch (JSONException e) {
  15.             e.printStackTrace();
  16.         }
  18.     }, error -> {
  19.         // 处理错误
  20.     });
  22.     requestQueue.add(request);
  23. }

我一直在使用 Volley 库来获取 JSON 并解析它。

英文:

I have been trying to populate the autocompletetextview with JSON using an API but it's not working as the JSON API does not have an Array name. If I try to use some other API that does have an array name it's working fine.

This is the example link for the API.

I have tried implementing this answer but it's not working.

无法在Android中使用未命名的JSON数组填充AutocompleteTextView。

This is the structure of the API.

And this is my method.

  1. private void populateEduList() {
  2.     List&lt;String&gt; responseList = new ArrayList&lt;&gt;();
  3.     String url = &quot;https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon&quot;;
  4.     JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, response -&gt; {
  6.         try {
  7.             JSONArray jsonArray = new JSONArray(response);
  8.             for (int i = 0; i &lt; jsonArray.length(); i++){
  9.                 JSONObject object = jsonArray.getJSONObject(i);
  10.                 responseList.add(object.getString(&quot;name&quot;));
  11.                 ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
  12.                 mAutoCompEdu.setAdapter(adapter);
  13.             }
  14.         } catch (JSONException e) {
  15.             e.printStackTrace();
  16.         }
  18.     }, error -&gt; {
  19.         //do something for the error
  20.     });
  22.     requestQueue.add(request);
  23. }

I have been using the Volley Library to fetch the JSON and parse it.

这是答案，如果 JSON 数组没有 "Name"，我们需要使用 StringRequest 而不是 JsonObjectRequest 来获取并在自动完成文本视图中显示 JSON。

更新的代码。

  1. private void populateEduList() {
  2.     List<String> responseList = new ArrayList<>();
  3.     String url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
  4.     StringRequest request = new StringRequest(Request.Method.GET, url, response -> {
  5.         try {
  6.             JSONArray jsonArray = new JSONArray(response);
  7.             for (int i = 0; i < jsonArray.length(); i++){
  8.                 JSONObject object = jsonArray.getJSONObject(i);
  9.                 responseList.add(object.getString("name"));
  10.                 Log.d("hasjkd", object.getString("name"));
  11.                 ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
  12.                 mAutoCompEdu.setAdapter(adapter);
  13.             }
  14.         } catch (JSONException e) {
  15.             e.printStackTrace();
  16.         }
  18.     }, error -> {
  19.         // 处理错误的操作
  20.     });
  22.     requestQueue.add(request);
  23. }
英文:

This is the answer, to fetch and display JSON in an autocompleteTextView if the JSON Array does not have a Name, we have to use StringRequest instead of JsonObjectRequest.

Updated Code.

  1. private void populateEduList() {
  2.         List&lt;String&gt; responseList = new ArrayList&lt;&gt;();
  3.         String url = &quot;https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon&quot;;
  4.         StringRequest request = new StringRequest(Request.Method.GET, url, response -&gt; {
  5.             try {
  6.                 JSONArray jsonArray = new JSONArray(response);
  7.                 for (int i = 0; i &lt; jsonArray.length(); i++){
  8.                     JSONObject object = jsonArray.getJSONObject(i);
  9.                     responseList.add(object.getString(&quot;name&quot;));
  10.                     Log.d(&quot;hasjkd&quot;, object.getString(&quot;name&quot;));
  11.                     ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
  12.                     mAutoCompEdu.setAdapter(adapter);
  13.                 }
  14.             } catch (JSONException e) {
  15.                 e.printStackTrace();
  16.             }
  18.         }, error -&gt; {
  19.             //do something for the error
  20.         });
  22.         requestQueue.add(request);
  23.     }
