Question

我正在构建一个android应用程序，需要向返回json对象并使用Volley库的API发出请求。

我能够获得响应，但是由于某种原因，我无法遍历json对象以接收所有键值。我已经尝试了for（int i = 0; i jsonObject.length（）但我仍然只得到1个结果。

private void jsonParse(){
    String url = "https://api.myjson.com/bins/wo1xc";
    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {

                    try {

                        JSONObject jsonObject = response.getJSONObject("exactMatchDomain");
                        JSONArray jsonArray = response.getJSONArray("suggestedDomains");

                        for(int i = 0; i < jsonArray.length(); i++){

                            JSONObject suggestedDomains = jsonArray.getJSONObject(i);

                            String domain = suggestedDomains.getString("domain");
                            String listPrice = suggestedDomains.getString("listPrice");

                            mTextViewResult.append(domain + ", " + listPrice + "\n\n"  );

                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

            error.printStackTrace();

        }
    });

    mQue.add(request);

您应该这样做：

JSONArray jsonArray = response.getJSONArray("suggestedDomains");
    for(int i = 0; i < jsonArray.length(); i++) {
        JSONObject suggestedDomains = jsonArray.getJSONObject(i);
        String domain = suggestedDomains.getString("domain");
        String listPrice = suggestedDomains.getString("listPrice");
        mTextViewResult.append(domain + ", " + listPrice + "\n\n"  );
}

由于回应：

{
"exactMatchDomain": {
"available": true,
"id": "domain",
"domain": "hyuirhejkyuiys.com",
"productId": 101,
"listPrice": "$13.99",
"salePrice": "$13.99",
"extendedValidation": false,
"disclaimer": null
},
"suggestedDomains": [
{
  "id": "domain",
  "domain": "hyuirhejkyuiys.net",
  "available": true,
  "productId": 12001,
  "listPrice": "$18.99",
  "salePrice": "$18.99",
  "extendedValidation": false,
  "disclaimer": null
},
{
  "id": "domain",
  "domain": "hyuirhejkyuiys.org",
  "available": true,
  "productId": 12101,
  "listPrice": "$19.99",
  "salePrice": "$9.99",
  "extendedValidation": false,
  "disclaimer": null
},
{
  "id": "domain",
  "domain": "hyuirhejkyuiys.info",
  "available": true,
  "productId": 201,
  "listPrice": "$21.99",
  "salePrice": "$4.99",
  "extendedValidation": false,
  "disclaimer": null
},
{
  "id": "domain",
  "domain": "hyuirhejkyuiys.co",
  "available": true,
  "productId": 56401,
  "listPrice": "$34.99",
  "salePrice": "$9.99",
  "extendedValidation": false,
  "disclaimer": null
},
{
  "id": "domain",
  "domain": "thehyuirhejkyuiys.com",
  "available": true,
  "productId": 101,
  "listPrice": "$13.99",
  "salePrice": "$13.99",
  "extendedValidation": false,
  "disclaimer": null
}
],
"disclaimer": "Taxes and ICANN fee not included in price

}

我建议您使用Retrofit 2代替Volley。
