无法在奥利奥(Oreo)中更改语言 [英] Unable to change language in Oreo

问题描述

我正在尝试在我的应用中使用阿拉伯语和英语.在运行于Android Nougat或更低版本的设备上，其工作正常.但这不适用于oreo设备. API 26中是否有一些新的代码要求?我正在使用下面的代码.

I'm trying to use Arabic and English in my app. Its working fine on devices running on android Nougat or below. But it's not working on oreo devices. Is there some new code requirement in API 26? I am using the code below.

public void changeLanguage(Context context, String language) {
    Locale locale = new Locale(language);
    Locale.setDefault(locale);
    Configuration config = context.getResources().getConfiguration();
    config.setLocale(locale);
    context.createConfigurationContext(config);
    context.getResources().updateConfiguration(config, context.getResources().getDisplayMetrics());
}

并且我将"en"和"ar"作为语言参数传递.

and I'm passing "en" and "ar" as language argument.

推荐答案

设置新的Locale时，应重新启动Activity.您可以使用下一个代码片段执行该操作:

When you set new Locale you should restart your Activity. You can perform it using the next snippet of code:

private void restartActivity() {
    Intent intent = getIntent();
    finish();
    startActivity(intent);
}

然后您的changeLanguage()方法将以另一种方式显示:

Then your changeLanguage() method will look in a next way:

public void changeLanguage(Context context, String language) {
    Locale locale = new Locale(language);
    Locale.setDefault(locale);
    Configuration config = context.getResources().getConfiguration();
    config.setLocale(locale);
    context.createConfigurationContext(config);
    context.getResources().updateConfiguration(config, context.getResources().getDisplayMetrics());

    restartActivity();
}
