Android的标签按钮：柄敲击/点击事件

问题描述：

请参见后续code片段：

Please see the follow code fragment:

// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, HomeTabActivity.class);

// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("home").setIndicator("Home", 
               res.getDrawable(R.drawable.ic_tab_home)).setContent(intent);
tabHost.addTab(spec);

现在，当我点击一个标签按钮，它显示了相应的活动，但后来我再次单击该按钮，我想也检测到这种点击，即使标签实际上是当前或主动标签，反正是有去做这个？我没有找到规范任何一组监听器方法。

Now when I click on an tab button, it shows corresponding activity, but then I click the button again, I want to also detect this click, even if the tab is actually the "current" or active tab, is there anyway to do this? I did not find any set listener method in spec.

答

好吧，我不认为这有什么，做，作为标签控件的一部分。有一对夫妇的事情，你可以尝试虽然。

Well, I don't think there is anything that does that as part of the tab control. There are a couple of things you could try though.

覆盖上HomeTabActivity的onNewIntent方法，看看他们每个选项卡被点击时发出的意图，但我对此表示怀疑。

您可以尝试把一个监听器上的的 getCurrentTabView 上TabHost方法

Override the onNewIntent method on the HomeTabActivity and see if they send the intent every time that the tab is tapped, though I doubt it.
You could try putting a listener on the view returned by the getCurrentTabView method on TabHost
