支持工具栏upNavigator隐藏问题

Question

我提出了这个问题：

https://code.google.com/p/android/issues/detail?id=189760

基本上是

public class Employees extends ArrayList implements Serializable
{

    private static final long serialVersionUID = 1L;

   /**
   Constructs a new employees object
   */
   public Employees()
   {
      super();
   }
}

HazelcastInstance hazelcastInstance = HazelcastHelper.getHazelcastInstance();
IMap<String, Employees> empMap = hazelcastInstance.getMap("employeesMap");

Employees empList = new Employees();
Employee employee = new Employee();
empList.add(employee);
empMap.put("companyId", employees);
empMap.executeOnKey("companyId", new IncSalaryEntryProcessor()); 

public static class ListValueEntryProcessor extends AbstractEntryProcessor<String, Employees>
{

    private static final long serialVersionUID = 1L;

    @Override
    public Object process(Entry<String, Employees> arg0) 
    {
        if(! (arg0.getValue() instanceof Employees))
        {
            System.out.println("Why so !");
        }
        // ClassCastException thrown here.
        Employees empList = arg0.getValue();
        return true;
    }

}

隐藏指示器隐藏使其只能隐身，而不会消失。
