NullPointerException - JSON, Volley, NetworkImage

Question

En essayant de charger l'activité suivante, j'ai rencontré une exception NullPoint, j'ai essayé de résoudre le problème, mais mes tentatives ont échoué.

En bref, il existe deux activités: une qui remplit une liste de tableaux et un clic sur un élément de la liste de tableaux amène l'utilisateur à une deuxième page d'activité (celle-ci) qui contient plus d'informations sur cet élément. La première activité se charge correctement sans aucune erreur, et la liste des tableaux avec l'image d'arrière-plan est affichée. Je reçois l'erreur inattendue lors du clic sur un élément de la liste de tableaux, ce qui amène l'utilisateur à la deuxième activité.

est Ci-dessous le message de chat journal:

Dans l'activité qui renseigne la liste des tableaux, l'élément étant peuplé de l'activité de l'élément unique (après utilisateur de cliquer sur un élément) est appelé

@Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      Intent intent = new Intent(CasualEventsActivity.this,CasualEventsSingleItemActivity.class); 

      intent.putExtra("list_item_name", container.get(position).getList_item_title()); 
      intent.putExtra("list_item_location", container.get(position).getList_item_location()); 
      intent.putExtra("single_list_item_description", container.get(position).getSingle_list_item_description()); 
      intent.putExtra("list_item_bac", container.get(position).getList_item_bac()); 
      startActivity(intent); //start Activity

Answer 1

changement

public String getList_item_bac() 
{ 
    return this.list_item_bac.toString(); 
} 

à

public Uri getList_item_bac() 
{ 
    return this.list_item_bac; 
} 

aussi j'ai changé cette

private final Events_List convertirAnuncio(JSONObject obj) throws JSONException { 
    long id = obj.getLong("id"); //id 
    String list_item_name = obj.getString("list_item_name"); 
    String list_item_location = obj.getString("list_item_location"); 
    String list_item_description = obj.getString("list_item_description"); 
    String single_list_item_description = obj.getString("single_list_item_description"); 
    String list_item_price = obj.getString("list_item_price"); 
    Uri uri = Uri.parse(obj.getString("list_item_bac")); 
    return new Events_List(id, list_item_location, single_list_item_description,list_item_name,list_item_description,list_item_price, uri, uri); 
} 

et changer

intent.putExtra("list_item_bac", container.get(position).getList_item_bac()); 

à

intent.putExtra("list_item_bac", container.get(position).getList_item_bac().toString()); 

donc vous obtiendrez:
