如何檢測彈出窗口外的點擊？

-3

嘿，我想檢測到點擊彈出窗口的外面，這裏是我的代碼如何檢測彈出窗口外的點擊？

builder = new AlertDialog.Builder(Context); 
    builder.SetTitle(Resource.String.rating_dialog_title); 
    builder.SetMessage(Resource.String.rating_dialog_desc); 
    builder.SetNegativeButton(Resource.String.yes, (s, e) => 
    { 
     SetAppRateStatus(AppRateStausEnum.RateNow); 
     IMvxWebBrowserTask help = new MvxWebBrowserTask(); 
     help.ShowWebPage("https://play.google.com/store/apps/details"); 
    }); 

    builder.SetNeutralButton(Resource.String.no, (s, e) => 
    { 
     SetAppRateStatus(AppRateStausEnum.RemindMeLater); 
    }); 

    builder.SetPositiveButton(Resource.String.never, (s, e) => 
    { 
     SetAppRateStatus(AppRateStausEnum.Never); 
    });

所以，請給我建議，檢測彈出窗口之外的點擊代碼，謝謝
