这里是我的代码。

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, URL, 
        new Response.Listener<JSONObject>() { 
         @Override 
         public void onResponse(JSONObject response) { 
          try { 
           JSONArray jsonArray = response.getJSONArray("result"); 

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


            String name = result.getString("name"); 
            String formatted_phone_number= result.getString("formatted_phone_number"); 
            textView.append(name + " " + " " + formatted_phone_number+ "\n"); 

           } 

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

          } 
         } 
        }, 
        new Response.ErrorListener() { 
         @Override 
         public void onErrorResponse(VolleyError error) { 
          Log.e("VOLLEY ", "ERROR"); 
         } 
        }); 
      requestQueue.add(jsonObjectRequest); 

Answer 1

试试这个：

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, URL, 
       new Response.Listener<JSONObject>() { 
        @Override 
        public void onResponse(JSONObject response) { 
         try { 
          JSONObject result = response.getJSONObject("result"); 

          String name = result.getString("name"); 
          String formatted_phone_number= result.getString("formatted_phone_number"); 
          textView.append(name + " " + " " + formatted_phone_number+ "\n"); 

         } catch (JSONException e) { 
          e.printStackTrace(); 
         } 
        } 
       }, 
       new Response.ErrorListener() { 
        @Override 
        public void onErrorResponse(VolleyError error) { 
         Log.e("VOLLEY ", "ERROR"); 
        } 
       }); 
     requestQueue.add(jsonObjectRequest);
