呼叫功能

Question

我proplem是：我有功能LoadTaskList()上MainActivity，但在CustomAdapter我叫LoadTaskList()但它並不活躍

CustomAdapter.cs

 public override View GetView(int position, View convertView, ViewGroup parent) 
     { 
      LayoutInflater inflater = (LayoutInflater)mainActivity.GetSystemService(Context.LayoutInflaterService); 
      View view = inflater.Inflate(Resource.Layout.row, null); 

      TextView txtTask = view.FindViewById<TextView>(Resource.Id.task_title); 
      Button btnDelete = view.FindViewById<Button>(Resource.Id.btnDelete); 


      txtTask.Text = taskList[position]; 

      btnDelete.Click += delegate { 
       string task = taskList[position]; 
       dbHelper.deleteTask(task); 

       mainActivity.LoadTaskList(); // here 
      }; 
      return view; 
     } 

MainActivity.cs

public void LoadTaskList() 
    { 
     List<string> taskList = dbHelper.getTaskList(); 
     if (mAdapter == null) 
     { 
      mAdapter = new CustomAdapter(this, taskList,dbHelper); 
      lstTask.Adapter = mAdapter; 
     } 

    }
