我有一个带有项目列表的xamarin选择器,我想在iPhone上按下"完成"按钮并在android上按下"Oke"按钮时删除选择器.
我有删除选择器的代码.但我不知道可能由哪个event_Handler.

码:

Picker picker = new Picker
    {
        Title = "What's in the slot?",
        VerticalOptions = LayoutOptions.CenterAndExpand
        //HorizontalOptions = LayoutOptions.Center 

    };

private void Displaypickerview(int row, int column)
    {
        if (status == "filling board")
        {
            foreach (string text in pickerText)
            {


picker.Items.Add(text);
        }
        foreach (string ore in oreLevels)
        {
            picker.Items.Add(ore);
        }


        picker.SelectedIndexChanged += (sender, args) =>
        {
            if (picker.SelectedIndex == -1)
            {

            }
            else
            {
                //change value of cell and button
                Picker picker = (Picker)sender;
                int index = picker.SelectedIndex;

                if …
