点击按钮切换语言 [英] Clicking a button to switch the language
问题描述
当我单击sub_changelang"按钮时,它应该将程序语言更改为例如法语.我得到了以下代码来更改语言环境,但我不知道如何刷新/更新应用程序以将语言更改为法语.
When I click on the "sub_changelang" button, it should change the program language to French for example. I got the following code to change the locale but I have no idea how to refresh/ pdate the app to change the language to French.
Button cl = (Button) findViewById(R.id.sub_changelang);
cl.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
Locale locale = new Locale("fr_FR");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
}
});
它不起作用.我该如何解决?我尝试添加:
It doesn't work. How can I fix it? I tried to add:
MainActivity.this.getResources().updateConfiguration(config, MainActivity.this.getResources().getDisplayMetrics());
但它没有用.我也试过了:
but it didn't work. I also tried:
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
它也没有用.
android:configChanges="locale"
在 AndroidMainfest.xml 中的 application -> activity 下设置
is set inside the AndroidMainfest.xml under application -> activity
推荐答案
我正在使用这段代码来设置语言环境
I am using this code to set locale
String languageToLoad = "fr_FR";
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
context.getResources().updateConfiguration(config,context.getResources().getDisplayMetrics());
Intent intent = new Intent(XYZ.this, XYZ.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
这里的上下文是应用程序基础上下文.也请尝试fr"而不是fr_FR",因为我正在为阿拉伯语语言环境工作,并且工作正常.
here context is application Base Context. Please also try "fr" instead of "fr_FR" because I am working for Arabic locale and its working fine.
更改区域设置后,您需要重新启动 Activity.
You need to restart your Activity after changing locale.
