Answer 1

If you are trying to set the text color on Android 5.0 or higher, you need to set the Theme of the MainActivity . Here is a simple one that should work...

[Activity(
    Label = "Some App Title", 
    Icon = "@drawable/icon", 
    MainLauncher = true, 
    Theme = "@style/android:Theme.Holo.Light"
)]

Answer 2

you can set in your app.xaml and it will override it

  <Style TargetType="NavigationPage">
    <Setter Property="BarBackgroundColor" Value="Red"/>
    <Setter Property="BarTextColor" Value="White"/>
  </Style>

在app.xaml中设置这些属性只能可靠地完成工作！

Answer 4

var page = new navigationPage(new yourPage());
page.BarBackgroundColor = Color.FromHex("#123456");

It will change yourPage() bar color
