app内动态切换语言

1. 设置context的语言

public static void setApplicationLanguage(Context context, Locale locale) {
        Resources resources = context.getApplicationContext().getResources();
        DisplayMetrics dm = resources.getDisplayMetrics();
        Configuration config = resources.getConfiguration();
        config.locale = locale;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            LocaleList localeList = new LocaleList(locale);
            LocaleList.setDefault(localeList);
            config.setLocales(localeList);
            context.getApplicationContext().createConfigurationContext(config);
            Locale.setDefault(locale);
        }
        resources.updateConfiguration(config, dm);
    }

2. 重置语言相关静态属性

• http header："Accept-Language"
• 其他属性

3. 重启activity

activity.recreate();

4. 完成
