Xamarin.Forms - StackLayout标签位于设备宽度之外
Xamarin.Forms - StackLayout标签位于设备宽度之外
提问于 2014-07-18 10:18:48
可以为元素设置百分比宽度吗？
我遇到的问题是第二个标签按下屏幕上的按钮，你怎么能强迫标签只占可用的空间。我试过设置元素的最小宽度。
new StackLayout
{
Orientation = StackOrientation.Horizontal,
Spacing = 0,
Children = {
new Label() { Text = "TITLE", HorizontalOptions = LayoutOptions.Start},
new Label() { Text = "fsdf dsfsd fsdfsdfs ewtrey vjdgyu jhy jgh tyjht rhyrt rgtu gtr ujtrey gt yu tgrt uh tyui y5r rtuyfgtj yrjhrytjtyjy jty t ruy ujh i rt", HorizontalOptions = LayoutOptions.Center, LineBreakMode = LineBreakMode.WordWrap},
new Button() { Text = "wee", HorizontalOptions = LayoutOptions.EndAndExpand}
}
}, 回答 1

尝试使用OnSizeAllocated(双宽、双高)，
代码在您的Xamarin.Forms页面中
protected override void OnSizeAllocated(double width, double height)
{
base.OnSizeAllocated(width, height);
Metrics.Instance.Width=width;
Metrics.Instance.Height=height;
}单例类保存宽度和高度并检查方向更改
public class Metrics
{
private static Metrics _instance;
protected SessionData ()
{
}
public double Width{ get; set; } //Width
public double Height{ get; set; } //Height
}创建堆栈布局
var StackchildSize = Metrics.Width/3;
new StackLayout
{
Orientation = StackOrientation.Horizontal,
Spacing = 0,
Children = {
new Label() { Text = "TITLE", HorizontalOptions = LayoutOptions.Start
WidthRequest=stackChildSize},
new Label() { Text = "<Your Text>", WidthRequest=stackChildSize,},
new Button() { Text = "wee", HorizontalOptions = LayoutOptions.EndAndExpand,
WidthRequest=stackChildSize,}
}},
