我想选项卡，转到第二个按钮，当我点击下一步按钮。在我看来，模型，这是我的命令下一个按钮

下面是我的code样品

  屏幕。

解决方案

我这个情况我不会用MvvmCross视图模型导航，因为使用您可能要创建一个自定义presenter。

你可以做的只是增加一个按钮点击活动或片段本身并使用以下code：

  VAR viewPager = view.FindViewById＆LT; ViewPager＆GT;（Resource.Id.viewpager）;
viewPager.SetCurrentItem（1，真）;
 

I have two screens which are linked to two tab buttons

1. Name
2. Duration

I would like tab to move to second button when I click Next button. In my view model this is my command for Next Button

Here is my code sample

public IMvxCommand NextCommand
{
    get
    {
        return new MvxCommand(() => ShowViewModel<RecyclerViewModel>());
    }
}

Rather than tab moving to next tab second view is opening in full screen.

First screen

解决方案

I this situation i would not use the MvvmCross ViewModel navigation, because to use that you probably have to create a custom presenter.

What you can do is just add a button click in the Activity or Fragment itself and use the following code:

var viewPager = view.FindViewById<ViewPager>(Resource.Id.viewpager);
viewPager.SetCurrentItem(1, true);
