你遇到的问题是你的内在ng-repeat位于你的外在之外，这意味着活动上下文是未知的。要解决此问题，您只需重新考虑您的div 布局，将一个ng-repeat包含在另一个中。例如：

<div ng-controller="Test">                     
   <div ng-repeat="evento in eventos | filter:categorySelected">
       <div ng-click = "eventSelected = {id: '{{evento.id}}'}">
           <div class="infoEvento">
               <div class="name_event">
                   {{evento.eventName}}
               </div> 
           </div>           
       </div>   
       <!-- Activitys -->
       <div ng-controller="Test">                     
           <div ng-repeat="activity in evento.activitys | filter:eventSelected">
               <div class="infoEvento">
                   <div class="name_event">
                       {{activitys.description}}
                   </div>            
               </div>                            
           </div>                     
       </div>            
    </div>                     
</div>
