Question

我在FundamentalView.axml

中有浮动按钮

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingBottom="22dp"
    android:paddingRight="22dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentEnd="true">
     <ImageButton
        android:id="@+id/addButton"
        android:layout_width="56dp"
        android:layout_height="56dp"
        android:src="@drawable/ic_add_white_24dp" />
   </FrameLayout>

在 FundamentalView.cs 中，我有一个click事件，它从视图底部触发一个片段，并带有选项（添加一个新人和新计算）。

 var addButton = view.FindViewById<ImageButton>(Resource.Id.addButton);
 addButton.Click += OnAddButtonClick;

 void OnAddButtonClick(object sender, System.EventArgs e)
 {
   var dialog = new CardDialogView();
   dialog.Show(((MainView)Activity).SupportFragmentManager, "CardDialogView");        
 }

CardDialogView.axml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFFFFF">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/dash_add_computer"
        android:textColor="@color/primary_text"
        android:textSize="16sp"
        android:text="New Calculation"
        local:MvxBind="Click NewCalculationCommand"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/dash_add_head"
        android:drawablePadding="28dp"
        android:textColor="@color/primary_text"
        android:textSize="16sp"
        android:text="New Person" />
</LinearLayout>

我的问题是如何使TextView可以点击并知道在mvvmcross中点击了哪个textview？

CardDialogView.cs

  public class CardDialogView : MvxDialogFragment<CardDialogViewModel>
  {

       public override Dialog OnCreateDialog(Bundle savedState)
        {
            .....
            return dialog;
        }
  }

CardDialogViewModel.cs

public class CardDialogViewModel : MvxViewModel
{

    public ICommand NewCalculationCommand
    {
        get
        {
         // it does not come here!
         return new MvxCommand(() => ShowViewModel<NewItemViewModel>(new { date = DateTime.Now }));
        }
    }
}

您可以像单击按钮一样绑定textview click：

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/dash_add_computer"
        android:textColor="@color/primary_text"
        android:textSize="16sp"
        local:MvxBind="Click NewCalculationCommand"
        android:text="New Calculation" />

对于第二个textview，将其绑定到另一个命令。这样，当调用相应的命令时，您将知道哪个textview触发了它。

MVVMCross中的TextView Clickable
