Question

更新

我创建了一个资产文件夹，里面是一个century.ttf文件。首先我得到了错误的编码问题，但在File was loaded in the wrong encoding 'UTF-8' while pasting new font to Assets Folder in Android Studio之后我按照这些步骤操作后，错误消息消失了。然后我写了我的MainActivity：

第四次更新：

Typeface typeface = Typeface.createFromAsset(getAssets(),"century.ttf");
Text.setTypeface(typrface);

然后我的应用突然停止了。

第四次更新：

Answer 1

按照以下链接中的说明进入清单文件并在应用程序xml标记下添加android：name =“the-below-implementation”

Answer 2

考虑到你在资产文件夹中使用ttf字体，生成这样的字体。

Typeface typeface = Typeface.createFromAsset(getAssets(),"YourFontName.ttf"); 
Text.setTypeface(typrface);

Answer 3

您的代码正在请求font/century（请参阅：Caused by: java.lang.RuntimeException: Font asset not found font/century）。实际资产是font/century.tff（根据您的评论），或者可能是font/century.ttf（这可能是TrueType字体更可能的文件扩展名）。

您提供的字体路径需要与assets/中的实际路径匹配，包括文件扩展名。

Answer 4

尝试将ttf文件放入＆＃34;字体＆＃34; ＆＃34;资产＆＃34;内的文件夹文件夹，然后更改源路径＆＃34; fonts / century.ttf＆＃34;。我的猜测是文件没有被识别为字体文件。

这就是我在其中一个项目中设置的方法：

无法在android studio中加载任何外部字体
