Android轻松实现多语言的方法示例

 public void setLanguage() {    //根据读取到存放在sp里面的数据 进行设置    Configuration configuration = getResources().getConfiguration();    SharedPreferences sharedPreferences = getSharedPreferences("key", MODE_PRIVATE);    int language = sharedPreferences.getInt("language", 0);    switch (language) {      case 0:        configuration.setLocale(Locale.CHINESE);        break;      case 1:        configuration.setLocale(Locale.ENGLISH);        break;    }    getResources().updateConfiguration(configuration, getResources().getDisplayMetrics());  }
