Ottieni più di 8 risultati di ricerca di immagini

Question

Sto utilizzando l'API di ricerca di immagini di Google nella mia app per Android per cercare immagini. Funziona bene, ma sto ricevendo solo 8 risultati di query.

Come posso ottenere più di 8 immagini? (O c'è un modo migliore per cercare le immagini?)

Qui di seguito è il mio codice:

public class getImagesTask extends AsyncTask<Void, Void, Void> 
     { 
      JSONObject json; 
      ProgressDialog dialog; 

      @Override 
      protected void onPreExecute() { 
       // TODO Auto-generated method stub 
       super.onPreExecute(); 

       dialog = ProgressDialog.show(GoogleSearchAPIExampleActivity.this, "", "Please wait..."); 
      } 

      @Override 
      protected Void doInBackground(Void... params) { 
       // TODO Auto-generated method stub 

       URL url; 
       try { 
        url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" + 
        "v=1.0&q="+strSearch+"&rsz=8"); //&key=ABQIAAAADxhJjHRvoeM2WF3nxP5rCBRcGWwHZ9XQzXD3SWg04vbBlJ3EWxR0b0NVPhZ4xmhQVm3uUBvvRF-VAA&userip=192.168.0.172"); 

       URLConnection connection = url.openConnection(); 
       connection.addRequestProperty("Referer", "http://technotalkative.com"); 

       String line; 
       StringBuilder builder = new StringBuilder(); 
       BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); 
       while((line = reader.readLine()) != null) { 
        builder.append(line); 
       } 

       System.out.println("Builder string => "+builder.toString()); 

       json = new JSONObject(builder.toString()); 
       } catch (MalformedURLException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (JSONException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
       return null; 
      } 

      @Override 
      protected void onPostExecute(Void result) { 
       // TODO Auto-generated method stub 
       super.onPostExecute(result); 

       if(dialog.isShowing()) 
       { 
        dialog.dismiss(); 
       } 

       try { 
        JSONObject responseObject = json.getJSONObject("responseData"); 
        JSONArray resultArray = responseObject.getJSONArray("results"); 

        listImages = getImageList(resultArray); 
        SetListViewAdapter(listImages); 
        System.out.println("Result array length => "+resultArray.length()); 
       } catch (JSONException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

      } 
     }

Answer 1

url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" + 
         "v=1.0&q="+strSearch+"&rsz=8&start=0"); 

Qui è possibile ottenere 64 risultati di immagine solo utilizzando questa API.

Ora cosa succede, se si imposta variable=9, aggiungerà un'altra immagine in uscita, ma la prima immagine sarà sparita (come possiamo ottenere solo 8 immagini per pagina).

Ora quando si imposta variable=8, si ottengono le 8 immagini successive (numero di pagina2 con le successive 8 immagini).

Di nuovo, se si imposta variable=16, si ottengono le 8 immagini successive (numero di pagina 3 con le successive 8 immagini).

Di nuovo, se si imposta variable=24, si ottengono le 8 immagini successive (numero di pagina4 con le successive 8 immagini) e così via.

Otterrete immagini fino a questo URL.

url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" + 
          "v=1.0&q="+strSearch+"&rsz=8&start=56"); 
(8th page) 

Ora da qui se si incrementa iniziare variabile come start=57, non ci sarà alcuna uscita.

Answer 2

Questo servizio sta chiamando solo 8 immagini. Per avere più di 8 immagini è necessario chiamare questo servizio più volte. Vedi questo answer, Questo è quello che vuoi.
