HttpResponse响应中出现错误= new client.execute（post）; 执行显示错误

Question

我正在制作android json listview应用。

HttpResponse response = new client.execute(post);出现错误HttpResponse response = new client.execute(post);

where执行显示错误。 它无法导入jar。

我也在项目中添加了httpclient-4.5.1.jar。

 try {
               HttpClient client = new DefaultHttpClient();
               HttpPost post = new HttpPost(params[0]);
               HttpResponse response = new client.execute(post);
                // StatusLine stat = response.getStatusLine();
                int status = response.getStatusLine().getStatusCode();

                if( status==200 ) {
                    HttpEntity entity = response.getEntity();
                    String data = EntityUtils.toString(entity);
                    JSONObject jObj = new JSONObject(data);

                    JSONArray jArray = jObj.getJSONArray("actors");

                    for (int i = 0; i < jArray.length(); i++) {
                        Actors actor = new Actors();

                        JSONObject jRealObject = jArray.getJSONObject(i);

                        actor.setName(jRealObject.getString("name"));
                        actor.setDescription(jRealObject.getString("description"));
                        actor.setDob(jRealObject.getString("dob"));
                        actor.setCountry(jRealObject.getString("country"));
                        actor.setHeight(jRealObject.getString("height"));
                        actor.setSpouse(jRealObject.getString("spouse"));
                        actor.setChildren(jRealObject.getString("children"));
                        actor.setImage(jRealObject.getString("image"));

                        actorsList.add(actor);
                    }

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

                return false;
        }

new关键字用于实例化对象，并且需要将要实例化的类的构造函数（而不是实例）作为单个参数。 就你而言

改变中

HttpResponse response = new client.execute(post);

与

HttpResponse response = client.execute(post);

将修复编译时错误。 client ，是DefaultHttpClient一个实例
