Xamarin Forms TabbedPage标题的中心文本 [英] Center text of a Xamarin Forms TabbedPage Title

问题描述

我有一个TabbedPage，其中有多个子页面，每个子页面都有一个标题. 当标题足够短以至于只有一行时，文本将完美居中，但是只要文本需要多于1行，它将不再居中.

i have a TabbedPage with multiple Child-Pages, with a title each. When the title is short enough to be single line the text gets centered perfectly, but as soon as the text needs more than 1 line it is no longer centered.

有人可以告诉我如何解决此问题吗?

Can anyone tell me how to fix this?

推荐答案

我认为不可能对所有平台都采用通用方式，而您必须采用特定于平台的方式.

I think it's impossible to do in common way for all platforms, and you have to do it in platform specific way.

对于android项目，我这样做的方式是: 在文件夹Resources/values中的Styles.xml文件中，我添加了样式

For android project I did it in such way: In file Styles.xml from folder Resources/values I added style

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="CustomTheme" 
        parent="@android:style/Theme.Holo">
        <item name="android:actionBarTabTextStyle">@style/CustomTab</item>
    </style>

    <style name="CustomTab" 
        parent="@android:style/Widget.Holo.ActionBar.TabText">
        <item name="android:gravity">center</item>
    </style>
</resources>

在MainActivity.cs中，我添加了

And in MainActivity.cs I added

[Activity(Theme = "@style/CustomTheme")]

对于Windows Phone，我发现了这篇文章 https://nocture.dk/2014/12/10/xamarin-forms-customizing-tabbed-page-header-title-windows-phone/，但没有尝试.

For Windows phone I found this article https://nocture.dk/2014/12/10/xamarin-forms-customizing-tabbed-page-header-title-windows-phone/, but didn't try it.

对于iOS，我也没有检查 http://jfarrell.net/2015/02/25/customizing-the-tab-bar-on-ios-with-xamarin-forms/.
