Android: Change language programmatically
提问by Paulius Vindzigelskis
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/2900144/1088229but 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.
我有 3 个按钮来更改语言。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但这样它只更改了一次语言环境，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changeLanguageListener()在监听器的末尾添加了，所以监听器被刷新了。
So is it ok, how i solved it or there is another way?
那么可以吗，我是如何解决的，还是有其他方法？
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);
}

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
因此，由于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，因此所有内容都会刷新。没有找到其他更好的解决方案

Resources res = context.getResources();
// Change locale settings in the app.
DisplayMetrics dm = res.getDisplayMetrics();
android.content.res.Configuration conf = res.getConfiguration();
conf.locale = new Locale(language_code.toLowerCase());
res.updateConfiguration(conf, dm);
If you have language specific content - you can change that base on the setting.## Heading ##
如果您有特定于语言的内容 - 您可以根据设置更改该内容。## 标题 ##

I would not recommend to change the language within your application. A better solution would be a button that opens the systems locale settings. You can use the following intent for this.
我不建议在您的应用程序中更改语言。更好的解决方案是打开系统区域设置的按钮。您可以为此使用以下意图。
startActivityForResult(new Intent(android.provider.Settings.ACTION_LOCALE, 0);
