如何在android中更改多个图像的src？

Question

我想更改html内容中每个图片的来源。 源更改后，我想在webview中显示html内容。 这是我试图执行的代码。 此代码的问题是它将所有图像更改为最后解析的图像。

private void show_webview( String instruction ) {
   ParseJSON pj = new ParseJSON(instruction);
   pj.parseJSON();
   String[] instructions = ParseJSON.instruction;
   for( int i = 0; i < instructions.length; i++ ) {
      instructions[i] = instructions[i].replaceAll("Â"," ");
      Document doc = Jsoup.parse(instructions[i]);
      Elements img = doc.getElementsByTag("img");
      int no_imgs = img.size();
      int im=0;
      String src = null;
      String img_src[] = new String[no_imgs];
      for (Element el:img) {
         src = el.absUrl("src");
         downloadImages(src);
         img_src[im] =src;
         im++;
      }
      for (int x=0; x< img_src.length; x++) {
         int indexname = img_src[x].lastIndexOf("/");
         if (indexname == img_src[x].length()) {
            img_src[x]= img_src[x].substring(x, indexname);
         }
         indexname = img_src[x].lastIndexOf("/");
         String name = img_src[x].substring(indexname, img_src[x].length());
         Log.d("Image name", name);
         Element image1 = doc.select("img").first();
         String img_url = image1.absUrl("src");
         if (img_src[x].contains(name.toLowerCase())) {
            Boolean isSDPresent =
               Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED);
            if (isSDPresent) {
               Elements image = doc.select("img[src]");
               String imagePath = "file://"+Environment.getExternalStorageDirectory().getAbsolutePath() + "/rreadyreckoner_images" + name;
               image.attr("src", imagePath);
               Log.d("PATH", imagePath);
            }
            else {
               Elements image = doc.select("img[src]");
               String imagePath = "file://"+"/storage/emulated/0/rreadyreckoner_images"+name;
               image.attr("src", imagePath);
            }
         }
      }
      webView.getSettings().setJavaScriptEnabled(true);
      webView.getSettings().setAllowFileAccess(true);
      webView.getSettings().setBuiltInZoomControls(true);
      webView.getSettings().setLoadsImagesAutomatically(true);
      webView.loadDataWithBaseURL( "", String.valueOf(doc), "text/html", "utf-8", "" );
      Log.d("Instruction",instructions[i]);
   }
}
