Question

我正在尝试在listpicker的fullmode中设置背景。我已经看到了这个：http://www.geekchamp.com/tips/listpicker-fullscreen-mode-background-problem-workaround但它似乎不适用于Windows Phone 8 ListPicker，因为模板不同？

这是我的模板：

    <ControlTemplate x:Key="ListPickerControlTemplate" TargetType="toolkit:ListPicker">
    <StackPanel>
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="PickerStates">

希望这会对你有所帮助。只需在App.xaml.cs文件构造函数中添加以下行：

((SolidColorBrush)App.Current.Resources["PhoneChromeBrush"]).Color = GetColorFromHexa("#1589FF").Color;

///Conert hexa decimal color value to solidcolorBrush
SolidColorBrush GetColorFromHexa(string hexaColor) 
{
    byte r = Convert.ToByte(hexaColor.Substring(1, 2), 16);
    byte g = Convert.ToByte(hexaColor.Substring(3, 2), 16);
    byte b = Convert.ToByte(hexaColor.Substring(5, 2), 16);
    SolidColorBrush soliColorBrush = new SolidColorBrush(Color.FromArgb(0xFF, r, g, b));
    return soliColorBrush;
}

您可以克隆Toolkit源代码中找到的ListPickerPage.xaml，更改您喜欢的任何内容，并将ListPicker :: PickerPageUri设置为指向您自己的ListPickerPage副本。
