有没有办法为整个应用程序设置字体样式

我正在尝试为我的应用程序应用自定义字体样式。我知道:

Typeface tf = Typeface.createFromAsset(getAssets(),"font.ttf");
text.setTypeface(tf);

但我想为整个应用程序应用自定义字体样式,包括操作栏标签和所有文本视图。

是否有一种“晚餐”方式为整个应用程序应用自定义字体?

您无法在一个点上为整个应用程序设置自定义字体,但您必须自己为每个视图设置字体。

无法设置整个应用程序字体,但如果您正在寻找更通用的编程解决方案,我创建了一个静态类,可用于设置整个视图的字体(Activity UI)。请注意,我正在使用Mono(C#),但您可以使用Java轻松实现它。

您可以将此类传递给您要自定义的布局或特定视图。如果你想要超高效,可以使用Singleton模式实现它。

public static class AndroidTypefaceUtility 
{
    static AndroidTypefaceUtility()
    {
    }
    //Refer to the code block beneath this one, to see how to create a typeface.
    public static void SetTypefaceOfView(View view, Typeface customTypeface)
    {
    if (customTypeface != null && view != null)
    {
            try
            {
                if (view is TextView)
                    (view as TextView).Typeface = customTypeface;
                else if (view is Button)
                    (view as Button).Typeface = customTypeface;
                else if (view is EditText)
                    (view as EditText).Typeface = customTypeface;
                else if (view is ViewGroup)
                    SetTypefaceOfViewGroup((view as ViewGroup), customTypeface);
                else
                    Console.Error.WriteLine("AndroidTypefaceUtility: {0} is type of {1} and does not have a typeface property", view.Id, typeof(View));
                }
                catch (Exception ex)
                {
                    Console.Error.WriteLine("AndroidTypefaceUtility threw:\n{0}\n{1}", ex.GetType(), ex.StackTrace);
                    throw ex;
                }
            }
            else
            {
                Console.Error.WriteLine("AndroidTypefaceUtility: customTypeface / view parameter should not be null");
            }
        }

        public static void SetTypefaceOfViewGroup(ViewGroup layout, Typeface customTypeface)
        {
            if (customTypeface != null && layout != null)
            {
                for (int i = 0; i < layout.ChildCount; i++)
                {
                    SetTypefaceOfView(layout.GetChildAt(i), customTypeface);
                }
            }
            else
            {
                Console.Error.WriteLine("AndroidTypefaceUtility: customTypeface / layout parameter should not be null");
            }
        }

    }

在您的活动中,您需要创建一个Typeface对象。我使用放在我的Resources / Assets /目录中的.ttf文件在OnCreate()中创建我的。确保该文件在其“属性”中标记为Android资产。

protected override void OnCreate(Bundle bundle)
{               
    ...
    LinearLayout rootLayout = (LinearLayout)FindViewById<LinearLayout>(Resource.Id.signInView_LinearLayout);
    Typeface allerTypeface = Typeface.CreateFromAsset(base.Assets,"Aller_Rg.ttf");
    AndroidTypefaceUtility.SetTypefaceOfViewGroup(rootLayout, allerTypeface);
}
