如何在android MvvmCross Xamarin中设置ProgressBar的可见性(How to set visibility for ProgressBar in android MvvmCross Xamarin)

 我正在尝试将ProgressBar visibility设置为GONE 。 
 
 
 在XML中 
 
<?xml version="1.0" encoding="utf-8"?>
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    local:MvxBind="Visibility Visibility(ProgressVisibility)"
    android:background="@drawable/sel_custom_progress" />
 
 在 ViewModel中 
 
private bool _progressVisibility;
public bool ProgressVisibility
{
    get { return _progressVisibility; }
    set { _progressVisibility = value; RaisePropertyChanged(() => ProgressVisibility); }
}
 
 
 我正在设置ProgressVisibility = false; 
 
 
 发生了什么 ：视图仍然可见，而不是隐藏。 如何解决这个问题。 

I am trying to set visibility for ProgressBar as GONE.
 
 
In XML
 
<?xml version="1.0" encoding="utf-8"?>
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    local:MvxBind="Visibility Visibility(ProgressVisibility)"
    android:background="@drawable/sel_custom_progress" />
 
In ViewModel
 
private bool _progressVisibility;
public bool ProgressVisibility
{
    get { return _progressVisibility; }
    set { _progressVisibility = value; RaisePropertyChanged(() => ProgressVisibility); }
}
 
 
I am setting ProgressVisibility = false;
 
 
What is happening: The view is still visible and not getting hidden. How to resolve this.
