vous devez analyser le JSON – Raghunandan

je l'ai fait, c'est un journal de mon JSONObject. –

poster le code d'analyse – Raghunandan

Vous devez d'abord analyser le fichier json, puis l'ajouter à un tableau ou à un tableau.

{ // json object node 
    "responseData": { // json object responseData 
     "results": [ // json array results 
      {   // json object node 
       "GsearchResultClass": "GimageSearch", 
       "width": "1916", 
       "height": "2608", 
       "imageId": "ANd9GcTGxX6RvwPECJIOp4O6kV618ZupfzDDb42Xu0ti-HXfwRUzIjGn5gh_JRUQ", 
       "tbWidth": "110", 
       "tbHeight": "150", 
       "unescapedUrl": "http://upload.wikimedia.org/wikipedia/commons/e/e9/Official_portrait_of_Barack_Obama.jpg" // get the url by the key

Parsing

ArrayList<String> urls = new ArrayList<String>(); 
JSONObject jb = new JSONObject("your json string"); 
JSONObject response = jb.getJSONObject("responseData"); 
JSONArray jr = response.getJSONArray("results"); 

for(int i=0;i<jr.length();i++) 
{ 
     JSOnObject jb1 =(JSONObject) jr.get(i); 
     String url = jb1.getString("unescapedUrl"); 
     urls.add(url); 
     // use arraylist and the url to arraylist 
}

Comme dit dans les commentaires, vous devez utiliser JSONParsing.

Voir ceci: -

Object obj = jsonParser.parse(result.toString());   
JSONObject myJsonObject = (JSONObject) obj; 

url= (String) myInfoJsonObject.get("unescapedUrl");

Est-ce que l'étape ci-dessus pour toutes les clés dont les valeurs que vous souhaitez analyser.
