我试过类似的东西

 String data = EntityUtils.toString(response.getEntity());


           JSONObject jsonObj = new JSONObject(data);
           Object jj=jsonObj.getJSONObject("results").get("name");

但我得到了 JSONEXCEPTION

results 是一个数组而不是一个对象：

JSONObject jsonObj = new JSONObject(data);    
JSONArray results =jsonObj.getJSONArray("results");

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

  String name = result.getString("name");
  Log.d("tag", "name: " + name)
}

这里没有编译器，所以无法检查语法。
