如何使用异步任务在imageview上捕获和显示图像？

public class LoadImageTask extends AsyncTask<String, Void, Bitmap> {
    private ImageView imageView;

    public LoadImageTask(ImageView imageView) {
        this.imageView = imageView;
    }

    @Override
    protected Bitmap doInBackground(String... params) {
        String imageUrl = params[0];
        Bitmap bitmap = null;
        try {
            // 执行图像加载的耗时操作，例如从网络或本地存储中获取图像数据
            URL url = new URL(imageUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            bitmap = BitmapFactory.decodeStream(input);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bitmap;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        // 将获取到的图像数据设置给ImageView，以显示图像
        if (result != null) {
            imageView.setImageBitmap(result);
        }
    }
}

ImageView imageView = findViewById(R.id.imageView);
String imageUrl = "https://example.com/image.jpg";

LoadImageTask task = new LoadImageTask(imageView);
task.execute(imageUrl);
