动态更改对讲语言？ [英] Change Talkback language dynamically?

问题描述

我有一个带有翻译测验的应用程序，我想让盲人可以使用它。问题是，例如当我关注西班牙语句子时，Talkback会用英语阅读它。

I have an application with a translation quiz and I want to make it accessible to blind people. The problem is that when I focus on a Spanish sentence (for example), Talkback reads it in English. Is there any way to trigger the Spanish TTS dynamically in Java?

谢谢

推荐答案

是的，现在有！

您必须将字符串包装在 LocaleSpan （最小sdk 17）和最新版本的TalkBack可以即时切换语言。

You have to wrap the string in a LocaleSpan (min sdk 17) and the latest version of TalkBack can switch language on the fly.
