有人知道如何缩小字体大小，从而解决此问题吗?

Does anyone know how to make the fontsize smaller, thus fixing this issue?

推荐答案

您可以使用自定义渲染器来为TabbedPage创建渲染器，然后在渲染器中进行如下编码:

You can use Custom Renderers to create your renderer for TabbedPage, and then in the renderer you can code for example like this:

public class StyledTabbedPageRenderer : TabbedPageRenderer
{
    private Android.Views.View formViewPager = null;
    private TabLayout tabLayout = null;

    protected override void OnElementChanged(ElementChangedEventArgs<TabbedPage> e)
    {
        base.OnElementChanged(e);

        this.tabLayout = (TabLayout)this.GetChildAt(1);

        changeTabsFont();
    }

    private void changeTabsFont()
    {
        //Typeface font = Typeface.CreateFromAsset(Android.App.Application.Context.Assets, "fonts/" + Constants.FontStyle);
        ViewGroup vg = (ViewGroup)tabLayout.GetChildAt(0);
        int tabsCount = vg.ChildCount;
        for (int j = 0; j < tabsCount; j++)
        {
            ViewGroup vgTab = (ViewGroup)vg.GetChildAt(j);
            int tabChildsCount = vgTab.ChildCount;
            for (int i = 0; i < tabChildsCount; i++)
            {
                Android.Views.View tabViewChild = vgTab.GetChildAt(i);
                if (tabViewChild is TextView)
                {
                    //((TextView)tabViewChild).Typeface = font;
                    ((TextView)tabViewChild).TextSize = 6;

                }
            }
        }
    }
}
