如何在Xamarin.Droid中更改选项卡式页面指示器的颜色? [英] How to change color of tabbed page indicator in Xamarin.Droid?

问题描述

我正在使用 Xamarin.Forms 和可移植类库构建应用程序.我有一个选项卡式页面.我想更改选项卡式页面指示器的颜色.更改其余布局是我已经管理的事情，我唯一需要做的就是更改浅蓝色的选项卡式页面指示器，如下所示:

I'm building an application with Xamarin.Forms and a Portable Class Library. I have a tabbed page. I want to change the color of the tabbed page indicator. Changing the rest of the layout is something I already managed, the only thing I do need is to change the light blue tabbed page indicator like shown below:

我在Xamarin.Droid中找不到任何能正常工作的东西.这是使用以下内容创建选项卡式页面的代码:

I couldn't find anything that could work in Xamarin.Droid. This is the code that creates the tabbed page with content:

class TabbedPageTry : TabbedPage
{
    public TabbedPageTry()
    { 
        Title = "TabbedPage";

        var myPages = new CategoryDAO().GetCategories();
        foreach (var item in myPages)
        {
            Children.Add(new TabPage(item.CategoryID) { BindingContext = item });
        }
    }

    public class TabPage : ContentPage
    {
        public TabPage(int categoryID)
        {
            Padding = new Thickness(0, Device.OnPlatform(20, 0, 0), 0, 0);

            var listView = new ListView
            {

                SeparatorColor = Color.FromHex("#101010"),
                ItemsSource = new CourseDAO().GetCourses(),
                IsPullToRefreshEnabled = false,
                BackgroundColor = Color.White,
            };

            this.SetBinding(Page.TitleProperty, "Name");
            Content = listView;
        }
}

因为正在使用Xamarin.Forms将应用程序制作为Visual Studio，所以我的问题尚未得到解答.我发现的所有问题都是针对Android的，这是我正在寻找的否.我需要的是针对我的问题的C#解决方案.

Because the application is being made Visual Studio with Xamarin.Forms my question is not answered yet. All the question I found are for Android specific, this is NOT what I am looking for. What I need is the C# solution to my problem.

谢谢.

推荐答案

如果您在Android平台项目中使用AppCompat ，在TabLayout axml文件中，使用tabIndicatorColor属性来执行此操作:

If you are using AppCompat in your Android platform project, in your TabLayout axml file use the tabIndicatorColor property to do this:

<android.support.design.widget.TabLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/sliding_tabs"
   ....
    app:tabIndicatorColor="#123456" />
