image. save(f'result/image{i},ipg’) AttributeError:'numpy.ndarray’ object has no attribute 'save’

这个错误是因为 NumPy 数组没有 `save()` 方法。你需要使用 PIL 库中的 `Image.fromarray()` 方法将 NumPy 数组转换为 PIL Image 对象，然后再使用 Image 对象的 `save()` 方法来保存图像。

以下是一个示例代码，可以将 NumPy 数组保存为 JPEG 格式的图像：

from PIL import Image
import numpy as np

# 从 NumPy 数组创建 PIL Image 对象
img = Image.fromarray(np.uint8(array))

# 保存图像为 JPEG 格式
img.save('image.jpg')

请注意，`np.uint8()` 在将 NumPy 数组转换为 PIL Image 对象时是必需的，因为 PIL 只支持 8 位无符号整数图像。如果你的数组类型不是 `uint8`，则需要先将其转换为 `uint8`。

以下是一个简单的Android代码示例，用于从指定URL获取JSON数据并将其解析并显示在ListView上：

public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private List<News> newsList = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        listView = findViewById(R.id.list_view);
        new GetDataTask().execute("http://192.168.1.100:8080/news/newslist");

        // TODO: 将数据保存到本地
    }

    private void showData(List<News> newsList) {
        NewsAdapter adapter = new NewsAdapter(this, newsList);
        listView.setAdapter(adapter);
    }

    private class GetDataTask extends AsyncTask<String, Void, String> {
        @Override
        protected String doInBackground(String... urls) {
            String result = "";
            try {
                URL url = new URL(urls[0]);
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.setRequestMethod("GET");
                connection.setConnectTimeout(5000);
                connection.setReadTimeout(5000);
                if (connection.getResponseCode() == 200) {
                    InputStream in = connection.getInputStream();
                    ByteArrayOutputStream out = new ByteArrayOutputStream();
                    byte[] buffer = new byte[1024];
                    int len;
                    while ((len = in.read(buffer)) != -1) {
                        out.write(buffer, 0, len);
                    }
                    result = out.toString();
                    in.close();
                    out.close();
                }
                connection.disconnect();
            } catch (Exception e) {
                e.printStackTrace();
            }
            return result;
        }

        @Override
        protected void onPostExecute(String result) {
            try {
                JSONArray jsonArray = new JSONArray(result);
                for (int i = 0; i < jsonArray.length(); i++) {
                    JSONObject jsonObject = jsonArray.getJSONObject(i);
                    News news = new News();
                    news.setId(jsonObject.getInt("id"));
                    news.setTitle(jsonObject.getString("title"));
                    news.setContent(jsonObject.getString("content"));
                    news.setCommentCount(jsonObject.getInt("comment"));
                    news.setImageUrl(jsonObject.getString("image"));
                    newsList.add(news);
                }
                showData(newsList);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }
}

这里使用了AsyncTask来进行网络请求和数据的解析，并将解析后的数据通过自定义的Adapter显示在ListView上。在TODO处，可以将数据保存到本地。这里只是一个简单的示例，实际应用中还需要考虑异常情况和网络请求的优化等问题。

QT改错，#include "widget.h" #include "ui_widget.h" #include <QTime> #include <QTimer> #include <QPixmap> #include <iostream> #include <string> #include <QDebug> Widget::Widget(QWidget *parent) : QWidget(parent) , ui(new Ui::Widget) { ui->setupUi(this); this->count = 0; this->tm = new QTimer(this); this->tm->start(1000); this->ui->label_2->setText(QTime::currentTime().toString("yyyy-MM-dd hh:mm:ss")); QTime time(0,0,0,0); this->ui->timeNumber->display(time.toString("hh:mm:ss")); //初始化label QPixmap pic(":/images/1.ipg"); this->ui->label->setPixmap(pic); for (int i = 1; i <= 9; i ++){ QString file_path = ":/images/"; file_path = QString::number(i) + ".jpg"; ph_set.push_back(file_path); qDebug() << file_path << endl; } connect(this->tm,&QTimer::timeout,this,&Widget::update_tm); } Widget::~Widget() { delete ui; } void Widget::update_tm() { this->count ++; QTime time(0,0,0,0); this->ui->timeNumber->display(time.addSecs(count).toString("mm:ss")); this->ui->label_2->setText(QTime::currentTime().toString("hh:mm:ss")); } void Widget::on_beforeButton_clicked() { } void Widget::on_afterButton_clicked() { }

代码中的图片路径有误，应该将第13行的 "ipg" 改为 "jpg"。正确的代码如下：

#include "widget.h"
#include "ui_widget.h"
#include <QTime>
#include <QTimer>
#include <QPixmap>
#include <iostream>
#include <string>
#include <QDebug>

Widget::Widget(QWidget *parent)
    : QWidget(parent)
    , ui(new Ui::Widget)
{
    ui->setupUi(this);
    this->count = 0;
    this->tm = new QTimer(this);
    this->tm->start(1000);
    this->ui->label_2->setText(QTime::currentTime().toString("yyyy-MM-dd hh:mm:ss"));
    QTime time(0,0,0,0);
    this->ui->timeNumber->display(time.toString("hh:mm:ss"));
    //初始化label
    QPixmap pic(":/images/1.jpg");
    this->ui->label->setPixmap(pic);
    for (int i = 1; i <= 9; i ++){
        QString file_path = ":/images/";
        file_path = QString::number(i) + ".jpg";
        ph_set.push_back(file_path);
        qDebug() << file_path << endl;
    }
    connect(this->tm,&QTimer::timeout,this,&Widget::update_tm);
}

Widget::~Widget()
{
    delete ui;
}

void Widget::update_tm()
{
    this->count ++;
    QTime time(0,0,0,0);
    this->ui->timeNumber->display(time.addSecs(count).toString("mm:ss"));
    this->ui->label_2->setText(QTime::currentTime().toString("hh:mm:ss"));
}

void Widget::on_beforeButton_clicked()
{
}

void Widget::on_afterButton_clicked()
{
}
