MvvmCross Android binding Enabled not work with Cl

Question

I have a TextView bound with Enabled, Clickable and Click. When the activity is loaded, Enabled & Clickable were bound to false value but the TextView cannot be disabled & still be clickable. After changed the bound value to true & then false, the TextView is disabled.

I found that the issue was related to binding the Click event. Once Click is bound, the mentioned issue occurs. Without binding the Click event, it works as expected.

In the following sample code, the first 2 TextViews are ok. The last one with binding Click does not work.

BTW, I have this issue with TextInputEditText instead. I found the situation applies to TextView as well so I use TextView for illustration.

         <TextView
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:text="test textview can be disabled at load"
             style="@style/EntryTextStyle"
             local:MvxBind="       Enabled RouteMarker.ArrivalNotice" />
         <TextView
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:text="test textview with no click command, can be disabled at load"
             style="@style/EntryTextStyle"
             local:MvxBind="       Enabled RouteMarker.ArrivalNotice;
                                   Clickable RouteMarker.ArrivalNotice" />
         <TextView
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:text="test textview with click command cannot be disabled at load"
             style="@style/EntryTextStyle"
             local:MvxBind="       Enabled RouteMarker.ArrivalNotice;
                                   Clickable RouteMarker.ArrivalNotice;
                                   Click DoSomethingCommand" />

    private IMvxAsyncCommand _doSomethingCommand;
    public IMvxAsyncCommand DoSomethingCommand
    {
        get
        {
            _doSomethingCommand = _doSomethingCommand ?? new MvxAsyncCommand(async () =>
            {
                await Task.Delay(10);
            });
            return _doSomethingCommand;
        }
    }

Any idea how to fix?

Thanks

As Stuart said, there are some interaction between ICommand.CanExecute and the Enabled property. Switching the binding to :

local:MvxBind="Click DoSomethingCommand;Enabled RouteMarker.ArrivalNotice;Clickable RouteMarker.ArrivalNotice;"

Effect.
