我正在尝试以编程方式更改 textView 的字体，但我的应用程序不断崩溃。这就是我的做法：

//SET CUSTOM FONT FOR TIMER
    String fontPath = "fonts/voice_notepad_font.ttf";
    TextView timer = (TextView)findViewById(R.id.timer);
    Typeface tf = Typeface.createFromAsset(getAssets(), fontPath);
    timer.setTypeface(tf);

这是我正在使用的字体

我将自定义字体添加到 assets/fonts 文件夹并将其重命名为“voice_notepad_font”

才发现问题！我不知道为什么，但是 .ttf 是大写的（voice_notepad_font.TTF），这就是它崩溃的原因。

我刚刚将 String fontPath 更改为：

String fontPath = "fonts/voice_notepad_font.TTF"

现在它完美地工作了。

老实说，这从未发生过，每次我下载自定义字体时，.ttf 都是小写的。这就是为什么我不知道自己做错了什么。
