您可以使用以下代码为应用设置语言，这是英语，用您的语言替换en：

         Locale locale = new Locale("en"); 
         Locale.setDefault(locale);
         Configuration config = new Configuration();
         config.locale = locale;
         getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());

清单文件中的

写android:configChanges="locale"。

您可以随时让他们选择语言，但请记住除当前活动外所有活动语言都有变化，您必须重新开始当前活动。
