如何在Xamarin Forms水平StackLayout中均匀分布4个控件。我在iPhone 4S上看起来不错,但在iPhone 6或iPad上却很糟糕。水平堆栈布局是ListView中的列表项。我尝试过相对布局和1行网格。但是我看起来最好(在4S上)。感谢。
按顺序我有按钮,标签,标签和按钮。
stackLayout = new StackLayout {
Orientation = StackOrientation.Horizontal,
HorizontalOptions = LayoutOptions.Center
};
deleteButton.Image = "minus.png";
deleteButton.HorizontalOptions = LayoutOptions.Start;
//label text width may vary from 4 to 16 characters
displayLabel.SetBinding(Label.TextProperty, "Text");
displayLabel.HorizontalOptions = LayoutOptions.Center;
displayLabel.WidthRequest = 125;
//label text is always 8 characters
displayLabel2.SetBinding(Label.TextProperty, "Text2");
displayLabel2.HorizontalOptions = LayoutOptions.Center;
button2.Image = "plus.png";
button2.HorizontalOptions = LayoutOptions.EndAndExpand;
stackLayout.Children.Add(deleteButton);
stackLayout.Children.Add(displayLabel);
stackLayout.Children.Add(displayLabel2);
stackLayout.Children.Add(button2);

使用StackLayout:
using Xamarin.Forms;
var label1 = new Label() {
Text = "label1",
HorizontalOptions = LayoutOptions.FillAndExpand, //OR CenterAndExpand
};
var label2 = new Label() {
Text = "label2",
HorizontalOptions = LayoutOptions.FillAndExpand, //OR CenterAndExpand
};
var label3 = new Label() {
Text = "label3",
HorizontalOptions = LayoutOptions.FillAndExpand, //OR CenterAndExpand
};
var label4 = new Label() {
Text = "label4",
HorizontalOptions = LayoutOptions.FillAndExpand, //OR CenterAndExpand
};
var stackLayout = new StackLayout
{
Orientation = StackOrientation.Horizontal,
HorizontalOptions = LayoutOptions.FillAndExpand,
Children = {
label1,
label2,
label3,
label4,
}
};
RootPage.Children.Add(new ContentPage {
Padding = 10,
Content = stackLayout
});
使用网格:
using Xamarin.Forms;
var label1 = new Label() {
Text = "label1",
};
var label2 = new Label() {
Text = "label2",
};
var label3 = new Label() {
Text = "label3",
};
var label4 = new Label() {
Text = "label4",
};
var gridLayout = new Grid
{
HorizontalOptions = LayoutOptions.FillAndExpand,
ColumnDefinitions = new ColumnDefinitionCollection() {
new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) },
new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) },
new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) },
new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) },
},
RowDefinitions = new RowDefinitionCollection() {
new RowDefinition() { Height = GridLength.Auto }
}
};
gridLayout.Children.Add(label1, 0, 0);
gridLayout.Children.Add(label2, 1, 0);
gridLayout.Children.Add(label3, 2, 0);
gridLayout.Children.Add(label4, 3, 0);
RootPage.Children.Add(new ContentPage {
Padding = 10,
Content = gridLayout
});
