Question

我有一个用户可以预订的应用程序。我试图实现一个对话框，用户可以在其中导航定制他的预订，即

选择日期
添加额外内容
查看报价
确认预订

我写了一个布局来向用户显示导航步骤（前进，后退，取消等），但我希望上面提到的步骤拥有它自己的片段/布局。我还要提一下，创建对话框的初始调用来自片段。有谁知道如何实现这一目标？我找到了Fragment-bookingCustomization_DatePicker错误

private Dialog dialog;
private void BtnMakeBooking_Click(object sender, EventArgs e)
{
    dialog = new Dialog(this.Activity);
    dialog.RequestWindowFeature((int)WindowFeatures.ContextMenu);
    dialog.SetTitle("Booking Customization");
    dialog.SetContentView(Resource.Layout.Fragment_booking_customization);

    Fragment_bookingCustomization_DatePicker date = new Fragment_bookingCustomization_DatePicker();
    var fragManager = FragmentManager.BeginTransaction();
    fragManager.Replace(Resource.Id.relativeLayout1, date);
    fragManager.Commit();

    dialog.Show();
}

我写了一个布局来向用户显示导航步骤（前进，后退，取消等），但我希望上面提到的步骤拥有它自己的片段/布局。我还要提一下，创建对话框的初始调用来自片段。

从您的代码中，您试图直接从原始片段开始一个新片段，根据您的要求，这是不可能的。因此，只需注释掉启动新片段的代码将使您的项目有效。

private void BtnClick_Click(object sender, EventArgs e)
{
    dialog = new Dialog(this.Activity);
    dialog.RequestWindowFeature((int)WindowFeatures.ContextMenu);
    dialog.SetTitle("Booking Customization");
    //here your dialog already host it's own layout:
    dialog.SetContentView(Resource.Layout.Fragment_booking_customization);

    //You can't start a new fragment from this fragment. So just comment the following codes out
    //Fragment_bookingCustomization_DatePicker date = new Fragment_bookingCustomization_DatePicker();
    //var fragManager = FragmentManager.BeginTransaction();
    //fragManager.Replace(Resource.Id.relativeLayout1, date);//error
    //fragManager.Commit();

    dialog.Show();
}

如果您想知道如何间接打开其他片段中的片段，可以参考this case。
