Xamarin C#：尝试水平居中按钮会导致它离开屏幕

基本上，我试着用屏幕的百分比来放置一个按钮。百分比大小和百分比位置。该按钮位于X:0.5f和Y:0.0f，这意味着它应该位于屏幕顶部的中心

Button button = new Button(Application.Context);
int height = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.HeightPixels * heightPercent);
int width = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.WidthPixels * widthPercent);

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WrapContent, RelativeLayout.LayoutParams.WrapContent)
{
    LeftMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.WidthPixels * xPercent - (width / 2)),
    TopMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.HeightPixels * yPercent),
    BottomMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.HeightPixels * yPercent) + height,
    RightMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.WidthPixels * xPercent + (width / 2)),
    Width = width,
    Height = height
};


button.Tag = buttonID;
button.LayoutParameters = params1;

上面的代码会导致按钮离开屏幕，尽管这毫无意义。如果我将页边距更改为此

LeftMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.WidthPixels * xPercent),
TopMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.HeightPixels * yPercent),
BottomMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.HeightPixels * yPercent) + height,
RightMargin = Convert.ToInt32(Application.Context.Resources.DisplayMetrics.WidthPixels * xPercent) + width,

按钮将出现在屏幕上，但稍微向右偏移。我试图把它移到左边一半的大小，但我不知道为什么布局会异常。有什么提示吗

按钮如何添加到布局中：

int MaxWidth = Resources.DisplayMetrics.WidthPixels;
int MaxHeight = Resources.DisplayMetrics.HeightPixels;

base.OnCreate(bundle);
RelativeLayout layout = new RelativeLayout(this);

layout.SetMinimumHeight(MaxHeight);
layout.SetMinimumWidth(MaxWidth);

<BUTTON GETS CREATED HERE>

layout.AddView(button);
SetContentView(layout);

int MaxWidth=Resources.DisplayMetrics.WidthPixels；
int MaxHeight=Resources.DisplayMetrics.HeightPixels；
base.OnCreate（bundle）；
RelativeLayout布局=新的RelativeLayout（此）；
布局。设置最小高度（最大高度）；
布局。设置最小宽度（最大宽度）；
布局。添加视图（按钮）；
SetContentView（布局）；

Xamarin C#：尝试水平居中按钮会导致它离开屏幕

您可以使用来实现此功能，例如：

RelativeLayout layout = new RelativeLayout(this);
Button button = new Button(this);
button.Text = "Center Button";

RelativeLayout.LayoutParams parametros = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WrapContent, RelativeLayout.LayoutParams.WrapContent);
parametros.AddRule(LayoutRules.CenterHorizontal);
layout.AddView(button, parametros);

SetContentView(layout);

您在哪里将

按钮添加到布局？您的
按钮的父视图是什么？请发布您的代码。@YorkShen MSFT我添加了用于添加按钮的代码。
