android - 如何抑制 TTS.getAvailableLocales() 的警告消息

Question

我可以获得当前设备支持的区域设置列表，如下所示:

for (Locale each : Locale.getAvailableLocales())
    if(1 <= myTTS.isLanguageAvailable(each))
        supportedLocales.add(each);

但我的问题是，方法 isLanguageAvailable() 总是记录不支持的语言环境的警告消息，如下所示:

08-15 20:10:08.163  5056    5672    W   TTS Local voice not installed, we will not be able to do local fallback

每当我启动 TTS 应用程序时，我都会收到一堆这样的信息，但我真的不想要这些。

如何在我的发布版本中抑制这些不需要的警告消息？

Answer 1

一种解决方法是将 logcat 过滤器设置为除 TextToSpeech 之外的所有内容(您需要启用正则表达式):^((?! TextToSpeech).)*$

我认为您无法对来自核心 api 的日志执行任何操作。当您从某些手机进行调试并始终获取蓝牙或连接日志时，也会出现同样的问题。
