如何更改标签动态称号 [英] How to change the title of the Tab Dynamically

问题描述

我有三个选项卡，在我的应用程序。下一个选项卡的事件，我想换一个其他现有选项卡的标题。这是我们提供，同时增加了标签到TabHost称号。

I have three tabs in my Application. On an event under one Tab, i want to change the title of an another existing Tab. This is the title that we provide while adding the tabs to the TabHost.

例如：。TabHost.addTab（tabHost.newTabSpec（TAB2））setIndicator（我需要动态改变）setContent ....

Eg: TabHost.addTab(tabHost.newTabSpec("Tab2")).setIndicator("I need to be Changed dynamically").setContent....

在上面的例子中，我setIndicator（）下提供的TAB2的标题，应动态地改变。

In the above example, the title of the tab2 that i provided under setIndicator(), should be changed dynamically.

有没有办法做到这一点。

Is there any way to accomplish this.

推荐答案

除非你能找到一个更清洁的方法，您可以访问tabwidget本身。 包含在tabwidget是每个标签页，每个包含的ImageView和一个TextView相对布局。要直接访问TextView的选项卡中的索引为0，你可以这样做：

Unless you can find a cleaner method, you can access the tabwidget itself. Contained in the tabwidget are relative layouts for each of your tabs which each contain an imageview and a textview. To directly access the textview in the tab at index 0 you can do this:

mTabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title)

然后就转换为一个TextView，你可以修改它不过你想要的。以下为我工作：      ((TextView)mTabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title)).setText("New");

Then just cast as a textview and you can edit it however you want. The below worked for me: ((TextView)mTabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title)).setText("New");
