的Android的NoSuchMethodError被扔在ArrayAdapter构造

Question

我试图以定制一个ListView扩展一般的ArrayAdapter和我得到一个的NoSuchMethodError当我打的TpAdapter（我的扩展适配器）构造

这里被抛出是exteded ArrayAdapter TpAdapter

private class TpAdapter : ArrayAdapter<MobileTalkingPoint> 
    { 
     private MobileTalkingPoint[] items; 
     private Context outer_context; 

     public TpAdapter(Context context, int textViewResourceId, MobileTalkingPoint[] items) 
      : base(context, textViewResourceId, items) 
     { 
      this.items = items; 
      this.outer_context = context; 
     } 

     public override View GetView(int position, View convertView, ViewGroup parent) 
     { 
      View v = convertView; 

      if (v == null) 
      { 
       LayoutInflater vi = (LayoutInflater)outer_context.GetSystemService(Context.LayoutInflaterService); 
       v = vi.Inflate(Resource.Layout.ItemTalkingPoint, null); 
      } 
      MobileTalkingPoint tp = items[position]; 
      if (tp != null) 
      { 
       TextView tpDate = v.FindViewById<TextView>(Resource.Id.tpDate); 
       TextView tpTitle = v.FindViewById<TextView>(Resource.Id.tpTitle); 
       TextView tpType = v.FindViewById<TextView>(Resource.Id.tpType); 
       TextView tpBody = v.FindViewById<TextView>(Resource.Id.tpBody); 

       tpDate.Text = String.Format("{0:MM/dd/yy}", tp.TPDate); 
       tpTitle.Text = tp.Title; 
       tpType.Text = tp.Type; 
       tpBody.Text = tp.Descr; 
      } 

      return v; 
     } 
    } 

我实例化作为他们在活动如下：

 MobileTalkingPoint[] weaknesses = talkingPoints; 

     TpAdapter adapStrength = new TpAdapter(this, Resource.Layout.ItemTalkingPoint, strengths); 

而对于异常堆栈跟踪如下：

注意我使用单声道的Android使用Visual Studio 2010

Answer 1

我不知道如果这是单声道的错误对于Android的或没有（好像它可能是，虽然），但如果您修改适配器采取一个IList，而不是一个数组，问题消失：

private class TpAdapter : ArrayAdapter<MobileTalkingPoint> 
{ 
    public TpAdapter(Context context, int textViewResourceId, IList<MobileTalkingPoint> items) 
     : base(context, textViewResourceId, items) 
    { 
    } 
} 

你可以仍然使用数组调用它，因此不需要修改：

MobileTalkingPoint[] points = { }; 
TpAdapter adapStrength = new TpAdapter(this, Resource.Layout.ItemTalkingPoint, points);
