安卓：更改语言编程 [英] Android: Change language programmatically

问题描述

我有3个按钮来改变语言。所以，我需要做的方法，在那里我可以设置监听器功能的按钮，可以改变语言每次他们是pressed。 我想这 http://stackoverflow.com/a/2900144/1088229 但这种方式改变区域只有一次，似乎这不工作了（如果我再次点击，它甚至不响应）。所以我加了 changeLanguageListener（）在听者的结束，让听众被刷新。

那么，这行，我怎么解决它，或有另一种方式？

 私人无效changeLanguageListener（）{
    最终按钮丁烯=（按钮）findViewById（R.id.button_language_en）;
    最终按钮butLt =（按钮）findViewById（R.id.button_language_lt）;
    最终按钮butRu =（按钮）findViewById（R.id.button_language_ru）;
    OnClickListener监听器=新OnClickListener（）{

        公共无效的onClick（视图v）{
            按钮，但是=（巴顿）V;
            资源RES = getResources（）;
            。串电流= res.getConfiguration（）locale.getCountry（）;
            Log.i（当前，电流）;
            字符串localeString =新的String（电流）;
            如果（but.equals（丁烯））{
                localeString =EN;
            }否则，如果（but.equals（butLt））{
                localeString =LT;
            }否则，如果（but.equals（butRu））{
                localeString =RU;
            }
            Log.i（点击，localeString）;

            如果（current.equalsIgnoreCase（localeString）及！＆安培; localeString.length（）大于0）{
                //在应用程序更改区域设置。
                DisplayMetrics DM = res.getDisplayMetrics（）;
                android.content.res.Configuration CONF = res.getConfiguration（）;
                conf.locale =新的语言环境（localeString.toLowerCase（））;
                res.updateConfiguration（CONF，DM）;
                //刷新菜单
                setGridView（）;
                //添加此行得到刷新监听器
                changeLanguageListener（）;
            }
        }
    };
    butEn.setOnClickListener（听众）;
    butLt.setOnClickListener（听众）;
    butRu.setOnClickListener（听众）;
}
 

解决方案

因此​​，只有两个活动（两种菜单模式），在那里我让改变语言环境，因为，我刚刚重新启动的活动区域设置更改后的权利，所以一切都将被刷新。没有找到任何其他更好的解决方案。

I have 3 buttons to change language. So I need to make method, where I could set listeners to buttons which could change language everytime they are pressed. I tried this http://stackoverflow.com/a/2900144/1088229 but this way it changes locale only once and seems that this doesn't work any more (if i click again, it doesn't even respond). So I added changeLanguageListener() in end of listener, so listener is refreshed.

So is it ok, how i solved it or there is another way?

private void changeLanguageListener() {
    final Button butEn = (Button) findViewById(R.id.button_language_en);
    final Button butLt = (Button) findViewById(R.id.button_language_lt);
    final Button butRu = (Button) findViewById(R.id.button_language_ru);
    OnClickListener listener = new OnClickListener() {

        public void onClick(View v) {
            Button but = (Button) v;
            Resources res = getResources();
            String current = res.getConfiguration().locale.getCountry();
            Log.i("Current", current);
            String localeString = new String(current);
            if (but.equals(butEn)) {
                localeString = "en";
            } else if (but.equals(butLt)) {
                localeString = "lt";
            } else if (but.equals(butRu)) {
                localeString = "ru";
            }
            Log.i("Clicked", localeString);

            if (!current.equalsIgnoreCase(localeString) && localeString.length() > 0) {
                // Change locale settings in the app.
                DisplayMetrics dm = res.getDisplayMetrics();
                android.content.res.Configuration conf = res.getConfiguration();
                conf.locale = new Locale(localeString.toLowerCase());
                res.updateConfiguration(conf, dm);  
                //refresh menu
                setGridView();
                //added this line to get refreshed listener
                changeLanguageListener();
            }               
        }
    };
    butEn.setOnClickListener(listener);
    butLt.setOnClickListener(listener);
    butRu.setOnClickListener(listener);
}

解决方案

So, because of only two activities (two menu modes) where i let to change locale, I just restart Activity right after locale change, so everything is refreshed. Didn't find any other better solution
