如何更改Android中的默认字体大小？

Question

我正在开发与字体相关的应用程序，在该应用程序中需要更改系统字体大小 。 我在Google中找不到任何示例。 如果有人有访问系统字体的经验，请帮助我解决此问题。谢谢。

我尝试了以下代码，但无法正常工作。

Settings.System.putFloat(getBaseContext().getContentResolver(),
                        Settings.System.FONT_SCALE, (float) 1.3);

好吧，经过大量搜索后，我发现了这个问题 ，其中，罗曼·盖伊（Romain Guy）提到不可能。

正如我在上面的评论中提到的那样，对于您所指的这个应用程序 ，他们在说明中还提到It may not work for all devices. Please try it and let me know (Settings > App log) if it does not work on your device. Starting from Android 4.2, this app only works on rooted devices due to Android disables 3rd party apps to change system UI configuration (color, font) unless you are using a rooted phone.
