無法滾動到結果結束時keyborad打開（Win​​dows Phone）

Question

我正在開發Windows Phone應用程序，我遇到了這個問題： 我有一個列表控件，它顯示我的搜索結果，但是當鍵盤打開我的一些結果是不可見的，因爲我的鍵盤...

有沒有辦法縮小控制，直到鍵盤邊界？爲了看到所有的結果。

即使打開鍵盤，我也想滾動到結果的結尾。

有我的解決方案

public class ResizeContentOnKeyboardShowingBehavior : Behavior<Page> 
    { 
     private readonly double _screenHeight; 

     public ResizeContentOnKeyboardShowingBehavior() 
     { 
      _screenHeight = Window.Current.Bounds.Height; 
     } 

     protected override void OnAttached() 
     { 
      InputPane.GetForCurrentView().Showing += OnKeyboardShowing; 
      InputPane.GetForCurrentView().Hiding += OnKeyboardHiding; 
     } 

     protected override void OnDetaching() 
     { 
      InputPane.GetForCurrentView().Showing -= OnKeyboardShowing; 
      InputPane.GetForCurrentView().Hiding -= OnKeyboardHiding; 
     } 

     private void OnKeyboardHiding(InputPane sender, InputPaneVisibilityEventArgs args) 
     { 
      var content = (FrameworkElement)AssociatedObject.Content; 

      content.Height = _screenHeight; 
     } 

     private void OnKeyboardShowing(InputPane sender, InputPaneVisibilityEventArgs args) 
     { 
      var content = (FrameworkElement)AssociatedObject.Content; 

      double keyboardHeight = sender.OccludedRect.Height; 

      content.Height = _screenHeight - keyboardHeight; 
     } 
    } 

基本行爲實現：

public abstract class Behavior : DependencyObject, IBehavior 
{ 
    public DependencyObject AssociatedObject { get; set; } 

    public virtual void Attach(DependencyObject associatedObject) 
    { 
     AssociatedObject = associatedObject; 
    } 

    public virtual void Detach() 
    { 
    } 
} 

public abstract class Behavior<T> : Behavior 
    where T : DependencyObject 
{ 
    [System.ComponentModel.EditorBrowsable(System.ComponentModel.EditorBrowsableState.Never)] 
    public new T AssociatedObject { get; set; } 

    public override void Attach(DependencyObject associatedObject) 
    { 
     base.Attach(associatedObject); 
     this.AssociatedObject = (T)associatedObject; 
     OnAttached(); 
    } 

    public override void Detach() 
    { 
     base.Detach(); 
     OnDetaching(); 
    } 

    protected virtual void OnAttached() 
    { 
    } 

    protected virtual void OnDetaching() 
    { 
    } 
} 

IBehavior接口是從Microsoft.Xaml.Interactivity命名空間從行爲SDK http://scr.hu/4m4q/pzl07

用法：

<Page x:Class="MainView" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:interactivity="using:Microsoft.Xaml.Interactivity" 
    xmlns:behaviors="using:Behaviors"> 

<interactivity:Interaction.Behaviors> 
    <behaviors:ResizeContentOnKeyboardShowingBehavior /> 
</interactivity:Interaction.Behaviors> 

<Grid> 

</Grid> 

或者相同的功能，但沒有任何行爲。剛添加到頁面代碼後面。

public sealed partial class MainPage : Page 
{ 
    private readonly InputPane _inputPane; 
    private readonly double _screenHeight; 

    public MainPage() 
    { 
     this.InitializeComponent(); 

     _screenHeight = Window.Current.Bounds.Height; 
     _inputPane = InputPane.GetForCurrentView(); 
    } 

    protected override void OnNavigatedTo(NavigationEventArgs e) 
    { 
     base.OnNavigatedTo(e); 

     _inputPane.Hiding += OnKeyboardHiding; 
     _inputPane.Showing += OnKeyboardShowing; 
    } 

    protected override void OnNavigatedFrom(NavigationEventArgs e) 
    { 
     base.OnNavigatedFrom(e); 

     _inputPane.Hiding -= OnKeyboardHiding; 
     _inputPane.Showing -= OnKeyboardShowing; 
    } 

    private void OnKeyboardShowing(InputPane sender, InputPaneVisibilityEventArgs args) 
    { 
     var content = (FrameworkElement)Window.Current.Content; 
     double keyboardHeight = sender.OccludedRect.Height; 
     content.Height = _screenHeight - keyboardHeight; 
    } 

    private void OnKeyboardHiding(InputPane sender, InputPaneVisibilityEventArgs args) 
    { 
     var content = (FrameworkElement)Window.Current.Content; 
     content.Height = _screenHeight; 
    } 
}
