Android:以编程方式更改语言 [英] Android: Change language programmatically

问题描述

我有 3 个按钮可以更改语言.所以我需要制作方法，在那里我可以将侦听器设置为每次按下时都可以更改语言的按钮.我试过这个 https://stackoverflow.com/a/2900144/1088229 但这样它只改变了一次语言环境，似乎这不再起作用(如果我再次单击，它甚至没有响应).所以我在监听器的末尾添加了 changeLanguageListener() ，所以监听器被刷新了.

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 https://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.

那可以吗，我是怎么解决的，还是有其他方法?

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);
}

推荐答案

因此，因为我只允许更改语言环境的两个活动(两种菜单模式)，我只是在语言环境更改后立即重新启动 Activity，所以一切都被刷新了.没有找到其他更好的解决方案

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
