建立在Android的preferences应用程序语言 [英] Set-up the application Language in Android Preferences

问题描述

我想申请语言根据用户preferences但直至现在它不工作，我怎么会喜欢它进行设置。

I would like the application language to be set according to the user preferences but up till now it doesn't work how I would like it to.

我设置的默认值：strings.xml中，也重视-ES具有的strings.xml里面西班牙语。我有一个菜单选项，它使用户在preference活动，在那里他可以阿蒙gother东西选择的语言。

I have set the default values: strings.xml and also values-es with a strings.xml inside in spanish. I have a menu option which brings the user to a Preference activity where he can amon gother things chose the language.

因此​​，这里的code一些摘录：

So here are some extracts of the code:

public class Preference extends PreferenceActivity implements
        OnSharedPreferenceChangeListener {
......
// Set up a listener whenever a key changes 
        getPreferenceScreen().getSharedPreferences()
                .registerOnSharedPreferenceChangeListener(this);


...}
//(......)

//and here I have the listener so when the language pref changes value the locale gets changed.
    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
            String key) {
        if (key.equals("listPref2")) {
            String idioma = sharedPreferences.getString("listPref2", "catala");
            if ("castella".equals(idioma)) {
                idioma = "es_ES";

                Locale locale = new Locale(idioma);
                Locale.setDefault(locale);
                Configuration config = new Configuration();
                config.locale = locale;
                getApplicationContext().getResources().updateConfiguration(config,
                        getBaseContext().getResources().getDisplayMetrics());
            }
        }
    }

所以，当我改变工作语言，但后来当我回来以后，或者重新启动语言回来到默认语言环境en_US和应用程序的语言被改回再次默认仿真器。我能做些什么来排序了这一点？

So when I change the language it works but then when I come back later or restart the emulator the language gets back to default locale the en_US and the app language gets changed back to default again. What can I do to sort that out?

我知道我能得到这个preference（我可以从我的所有活动获得），然后每次都设置了语言环境，但我觉得有点重是不是有办法做到这一点的更多的优雅的方式？

I know I can get this preference (which I can access to from all my activities) and then each time set up the locale but I find it a bit heavy isn't there a way to do it in a more elegant way?

如果用户设置了这样的语言时，他回来两天后，他没有再改变语言我想要做的就是。

What I would like to do is if the user sets up the language so when he comes back 2 days later he doesn't have to change the language again.

任何想法？

推荐答案

确定它可以帮助别人。我已经添加了如下因素的主要活动清单：

OK it may help someone. I have added the folowing to the main activity manifest:

安卓configChanges =区域设置

然后，当用户的动产的preferences我已经把一个确认按钮，然后此按钮，您的主要活动，这就是为什么lnagages被重置。

Then when the user choses the preferences I have put a confirm button and then this button brings you to main activity that is why the lnagages gets reset.

我有一个静态类，我有这个code要更改语言环境：

I have a static class where I have this code to change the locale:

public static void updateLanguage(Context context, String idioma) {
    if (!"".equals(idioma)) {
        if ("castella".equals(idioma)) {
            idioma = "es_ES";
        } else if ("catala".equals(idioma)) {
            idioma = "ca_ES";
        }
        Locale locale = new Locale(idioma);
        Locale.setDefault(locale);
        Configuration config = new Configuration();
        config.locale = locale;
        context.getResources().updateConfiguration(config, null);
    }
}

到底在每一次活动我喜欢他们的20我之前调用这个方法：

end at every activity I have like 20 of them I call this method before:

的setContentView（R.layout.list_event）;

使用这些方法时，我旋转屏幕的活动不更改语言 这里是一个链接到一个博客，帮助我： <一href="http://adrianvintu.com/blogengine/post/Force-Locale-on-Android.aspx">http://adrianvintu.com/blogengine/post/Force-Locale-on-Android.aspx

With these methods when I rotate the screen the activities don't change the language here is a link to a blog that helped me: http://adrianvintu.com/blogengine/post/Force-Locale-on-Android.aspx
