是否有可能刷新片段的视图 [英] Is it possible to refresh the view of a Fragment

问题描述

我改变了我的应用程序的编程的区域，像下面这样：

I changed the locale of my application programmatically, like following:

Resources res = context.getResources();

 DisplayMetrics dm = res.getDisplayMetrics();
 android.content.res.Configuration conf = res.getConfiguration();
 conf.locale = new Locale("cn");
 res.updateConfiguration(conf, dm);

在此，我想为刷新我的当前显示片段的视图来显示新的区域设置。

After this, I would like to refresh my currently displayed fragment's view to display with new locale settings.

所以，我首先得到当前片段（这是最新一期的 backstack ）：

So, I firstly get the current fragment (that's the latest one in backstack):

BackStackEntry latestEntry=fragMgr.getBackStackEntryAt(fragMgr.getBackStackEntryCount()-1);
String str=latestEntry.getName();
Fragment fragment=fragMgr.findFragmentByTag(str);

在我得到的目前呈现的片段，我想为刷新的查看，但怎么办呢？是否有可能在Android的刷新片段的视图

After I get the currently showing fragment, I would like to refresh its view, but how to do it? Is it possible in Android to refresh the view of a fragment

推荐答案

您可以简单地分离和附加片段如下

You can simply detach and attach fragment as below

    Fragment currentFragment = getFragmentManager().findFragmentByTag("FRAGMENT");
    FragmentTransaction fragTransaction = getFragmentManager().beginTransaction();
    fragTransaction.detach(currentFragment);
    fragTransaction.attach(currentFragment);
    fragTransaction.commit();

这将刷新视图和语言环境会改变

This will refresh the view and locale will change
