Mvvmcross Visibility in fluent binding

I have got EditText with swiss binding (last line):

<EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:MvxBind="Visibility Visibility(WebServiceEditVisible); Text EditTextWebServiceAdress" />

How can I write binding to Visibility plugin and to Text property using Fluent binding?

Solution

  • The fluent binding equivalent to the Swiss binding you have implemented would be:

    Resource file:

    <EditText
    android:id="@+id/your_edit_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

    Codebehind:

    var myEditText = view.FindViewById<EditText>(Resource.Id.your_edit_text);
var bindingSet = this.CreateBindingSet<YourView, YourViewModel>();

bindingSet.Bind(yourEditText).For(c => c.Text).To(vm => 
vm.EditTextWebServiceAdress);
bindingSet.Bind(yourEditText).For(c => c.Visibility).To(vm => 
vm.WebServiceEditVisible).WithConversion(new MvxVisibilityValueConverter());

bindingSet.Apply();

    This code would go in the OnCreateView override of your fragment. If you're working inside an activity, it would go inside OnCreate instead, and you'd need to change view.FindViewById<EditText>(Resource.Id.your_edit_text); to FindViewById<EditText>(Resource.Id.your_edit_text);.
