So , Wie bekomme ich Bild URL von diesem String

Answer 1

Try this:: 

Document doc = Jsoup.parse(html); 
     Elements element = doc.getAllElements(); 
     for(Element e: element) 
     { 
      Elements str = e.getElementsByTag("img"); 
      for(Element el: str) 
      {     
       String src= el.attr("src"); 
       System.out.println("The src:"+src); 
      } 
     } 

Answer 2

Sie können Regulärer Ausdruck verwenden, um das src Attribut von img Tag zu entsprechen.

diesen Code Versuchen Sie,

String mydata = "your html string"; 
String regex = "src\\s*=\\s*\"(.+?)\""; 

Pattern pattern = Pattern.compile(regex); 
Matcher matcher = pattern.matcher(mydata); 
List<String> imgUrls = new ArrayList<String>(); 
while (matcher.find()) { 
    imgUrls.add(matcher.group(1)); 
} 

//Load imgUrls into ImageViews using some image loader 

Für Imageloader können Sie Picasso oder Glide verwenden.

Answer 3

URL[] urlsimage; 
Bitmap[] TBM; 

JSONArray jsonArray = new JSONArray(Response); 

urlsimage=new URL[jsonArray.length()]; 
TBM=new Bitmap[jsonArray.length()]; 

for(int i=0; i < jsonArray.length(); i++){ 
JSONObject jsonObject = jsonArray.getJSONObject(i); 

Image[i]=jsonObject.getString("image"); 
    if(!Image[i].equals("null")) 
    { 
     urlsimage[i]=new URL(Image[i]); 
     TBM[i] = BitmapFactory.decodeStream(urlsimage[i].openConnection().getInputStream()); 
    } 
} 

img.setImageBitmap(TBM[0]);
