重新启动在一个TabActivity单个标签的活动？ [英] Restarting an activity in a single tab in a TabActivity?

问题描述

我有一个TabActivity。每个标签指向一个子活动。这个伟大的工程。

I have a TabActivity. Each tab point to a sub activity. This works great.

有什么聪明的方法来刷新活动标签之一？我只是想'重启'的标签＃3例如活动。不知道的好办法做到这一点以外的其他刷新支持建设以活动本身，或清除所有选项卡并重新创建所有的人。

Is there any clever way to refresh one of the activity tabs? I just want to 'restart' the activity in tab #3 for example. Not sure of a good way to do this other than building in refresh support to the activity itself, or clearing ALL the tabs and recreating all of them.

谢谢

推荐答案

略多于动态的解决方案：

Slightly more dynamic solution:

LocalActivityManager manager = getLocalActivityManager();
String currentTag = tabHost.getCurrentTabTag();
Class<? extends Activity> currentClass = manager.getCurrentActivity().getClass();
manager.destroyActivity(currentTag, true);
manager.startActivity(currentTag, new Intent(this, currentClass));
