我做了一个应用程序,它从不同的网址获取数据.我使用for循环使用jsoup lib从不同的URL获取数据.现在,这需要很多时间,例如5秒.
首先从url1中获取数据,然后从2中获取数据,然后从3中获取数据.
这就是我想的时间.

所以我想知道我们是否可以同时(多个线程)从不同的URL获取数据？

public  class Title extends AsyncTask <String,Void,Void> {

    String url,ver;
    Bitmap mIcon11 = null;
    ArrayList<App> appsList = new ArrayList<>();

    @Override
    protected Void doInBackground(String ... strings) {
        try {

            for (String string : strings) {
                Document document = Jsoup.connect(string).get();

                Elements a = document.select("div.AppCont");
                Elements b = a.select("article");
                Elements c = b.select("div.ImgDiv");
                Elements d = c.select("img");
                url = d.attr("src");

                InputStream in = new URL(url).openStream();
                mIcon11 = BitmapFactory.decodeStream(in);

                ver = b.get(0).text();
                String z = string.replace("https://a2zapk.com/History/","");
                z = z.replace("/","");

                PackageInfo pi = getApplicationContext().getPackageManager().getPackageInfo((z),PackageManager.GET_Meta_DATA);
                String versionName = pi.versionName;

                ver = ver + " (Installed Version: " +versionName + ")";
                appsList.add(new App(ver,mIcon11));

            }

        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
         add(appsList);
    }
