看起来不错，只需添加复选框点击，看一下。

public class MyCustomView : Java.Lang.Object, SimpleCursorAdapter.IViewBinder
{

    public bool SetViewValue(View view, Android.Database.ICursor cursor, int i)
    {
        if (view.Id == Resource.Id.action_bar)
        {
            // If the column is IS_STAR then we use custom view.
            int is_val = cursor.GetInt(i);
            CheckBox cb = (CheckBox)view;
            cb.Click += cb_Click;
            if (is_val != 0)
            {
                // set the visibility of the view to GONE
                cb.Checked = true;
                return true;
            }
            else
            {
                // cb.Checked = false; //in case you want to make it (uncheck)
                return true; 
            }
            // For others, we simply return false so that the default binding
            // happens.

        }
        return true;
    }

    void cb_Click(object sender, EventArgs e)
    {
        //Handle checkbox click because value will be cahnge while clicking on checkbox
    }
}

这段代码让我感谢你... :)

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath){

    var cell : CollectionViewCell = collectionView.cellForItemAtIndexPath(indexPath) as! CollectionViewCell
    cell.backgroundColor = UIColor.magentaColor()
    self.mediaModels[indexPath.row].isSelected  = true
    cell.selected = true
    cell.imageTicked.hidden = false
}
func collectionView(collectionView: UICollectionView, didDeselectItemAtIndexPath indexPath: NSIndexPath){

    var cell : CollectionViewCell = collectionView.cellForItemAtIndexPath(indexPath) as! CollectionViewCell
    cell.backgroundColor = UIColor.whiteColor()
    self.mediaModels[indexPath.row].isSelected  = false
    cell.selected = false
    cell.imageTicked.hidden = true
}
