Android 获取系统语言的实例(兼容7.0)

//获取 Locale 的方式有二

//方式一
Locale locale = getResources().getConfiguration().locale;

//方式二
Locale locale = Locale.getDefault();

//获取当前系统语言
locale.getLanguage();

//获取 Locale 的方式有二

//方式一
Locale locale = getResources().getConfiguration().locale;

//方式二
Locale locale = Locale.getDefault();

// 获取当前系统语言
String lang = locale.getLanguage() + "-" + locale.getCountry();

//获取 Locale 对象的正确姿势：

Locale locale；
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
  locale = getResources().getConfiguration().getLocales().get(0);
} else {
  locale = getResources().getConfiguration().locale;
}

//获取语言的正确姿势：

String lang = locale.getLanguage() + "-" + locale.getCountry();

Locale locale = Locale.getDefault();
MLog.e(locale.getLanguage() + "-" + locale.getCountry());

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
  LocaleList localeList = getResources().getConfiguration().getLocales();
  for (int i = 0; i < localeList.size(); i++) {
    MLog.e(i + " >1> " + localeList.get(i).getLanguage() + "-" + localeList.get(i).getCountry());
  }

  LocaleList localeList2 = LocaleList.getAdjustedDefault();
  for (int i = 0; i < localeList2.size(); i++) {
    MLog.e(i + " >2> " + localeList2.get(i).getLanguage() + "-" + localeList2.get(i).getCountry());
  }

  LocaleList localeList3 = LocaleList.getDefault();
  for (int i = 0; i < localeList3.size(); i++) {
    MLog.e(i + " >3> " + localeList3.get(i).getLanguage() + "-" + localeList3.get(i).getCountry());
  }

  LocaleList localeList4 = LocaleList.getEmptyLocaleList();
  for (int i = 0; i < localeList4.size(); i++) {
    MLog.e(i + " >4> " + localeList4.get(i).getLanguage() + "-" + localeList4.get(i).getCountry());
  }
}

Locale locale = Locale.getDefault();
//Locale.getDefault() 和 LocaleList.getAdjustedDefault().get(0) 同等效果，还不需要考虑版本问题，推荐直接使用
String language = locale.getLanguage() + "-" + locale.getCountry();

Locale locale;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
  locale = LocaleList.getDefault().get(0);
} else {
  locale = Locale.getDefault();
}
String language = locale.getLanguage() + "-" + locale.getCountry();
