从android URL下载imageview中加载的图片

// 导入必要的类
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;
import android.widget.ImageView;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

// 异步任务类，用于下载图片
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    private ImageView imageView;

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

    protected Bitmap doInBackground(String... urls) {
        String imageUrl = urls[0];
        Bitmap bitmap = null;
        try {
            URL url = new URL(imageUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream inputStream = connection.getInputStream();
            bitmap = BitmapFactory.decodeStream(inputStream);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return bitmap;
    }

    protected void onPostExecute(Bitmap result) {
        imageView.setImageBitmap(result);
    }
}

// 在需要加载图片的地方调用异步任务
String imageUrl = "https://example.com/image.jpg";
ImageView imageView = findViewById(R.id.imageView);
new DownloadImageTask(imageView).execute(imageUrl);
