Java 无法在Android中使用未命名的JSON数组填充AutocompleteTextview

我一直在尝试使用API用JSON填充autocompletetextview，但它不起作用，因为JSON API没有数组名。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

我试过实现这个答案，但它不起作用

这是API的结构

这是我的方法。

private void populateEduList() {
    List<String> responseList = new ArrayList<>();
    String url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, response -> {

        try {
            JSONArray jsonArray = new JSONArray(response);
            for (int i = 0; i < jsonArray.length(); i++){
                JSONObject object = jsonArray.getJSONObject(i);
                responseList.add(object.getString("name"));
                ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
                mAutoCompEdu.setAdapter(adapter);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

    }, error -> {
        //do something for the error
    });

    requestQueue.add(request);
}

private void populateEduList() {
        List<String> responseList = new ArrayList<>();
        String url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
        StringRequest request = new StringRequest(Request.Method.GET, url, response -> {
            try {
                JSONArray jsonArray = new JSONArray(response);
                for (int i = 0; i < jsonArray.length(); i++){
                    JSONObject object = jsonArray.getJSONObject(i);
                    responseList.add(object.getString("name"));
                    Log.d("hasjkd", object.getString("name"));
                    ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
                    mAutoCompEdu.setAdapter(adapter);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }

        }, error -> {
            //do something for the error
        });

        requestQueue.add(request);
    }

private void populatedulist（）{
List responseList=new ArrayList（）；
字符串url=”https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
JsonObjectRequest=新的JsonObjectRequest（request.Method.GET，url，null，response->{
试一试{
JSONArray JSONArray=新JSONArray（响应）；
for（int i=0；i{
//为这个错误做点什么
});
添加（请求）；
}

我一直在使用Volley库获取JSON并对其进行解析。

这就是答案，要在autocompleteTextView中获取和显示JSON，如果JSON数组没有名称，我们必须使用

StringRequest

而不是

JsonObjectRequest

更新代码。

private void populateEduList() {
    List<String> responseList = new ArrayList<>();
    String url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, response -> {

        try {
            JSONArray jsonArray = new JSONArray(response);
            for (int i = 0; i < jsonArray.length(); i++){
                JSONObject object = jsonArray.getJSONObject(i);
                responseList.add(object.getString("name"));
                ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
                mAutoCompEdu.setAdapter(adapter);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

    }, error -> {
        //do something for the error
    });

    requestQueue.add(request);
}

private void populateEduList() {
        List<String> responseList = new ArrayList<>();
        String url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
        StringRequest request = new StringRequest(Request.Method.GET, url, response -> {
            try {
                JSONArray jsonArray = new JSONArray(response);
                for (int i = 0; i < jsonArray.length(); i++){
                    JSONObject object = jsonArray.getJSONObject(i);
                    responseList.add(object.getString("name"));
                    Log.d("hasjkd", object.getString("name"));
                    ArrayAdapter adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, responseList);
                    mAutoCompEdu.setAdapter(adapter);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }

        }, error -> {
            //do something for the error
        });

        requestQueue.add(request);
    }

private void populatedulist（）{
List responseList=new ArrayList（）；
字符串url=”https://autocomplete.clearbit.com/v1/companies/suggest?query=amazon";
StringRequest=新的StringRequest（request.Method.GET，url，response->{
试一试{
JSONArray JSONArray=新JSONArray（响应）；
for（int i=0；i{
//为这个错误做点什么
});
添加（请求）；
}

您是否检查了是否收到响应？在您的请求中？通过邮递员它可以工作。我是在询问android studiono，它不是使用

StringRequest

获取objectsTry
