大家好，我正在从 XML 文件创建一个选项卡式导航。但是由于某种原因，我的循环只为活动选项卡和最后一个选项卡（在本例中为第四个选项卡）创建文本字段。
> 你可以在这里预览我的 Flash。<（我打开了文本框边框）
我的问题：
1.活动选项卡（浅色选项卡）的大小未根据文本字段的宽度正确调整
2.我的循环出于某种原因跳过了 2 个中间选项卡，但正确设置了第 4 个选项卡。
XML 选项卡标题：
- 这是第一个标签
- 第二个标签
- 第三个标签
- 第 4 个也是最后一个标签
似乎第二个和第三个选项卡的大小正确，但正如您在下面看到的那样，在尝试追踪第二个和第三个选项卡的文本时出现错误。
♥ 更新：添加了整个 TabMenu 类，希望能解决这个问题 :) 我现在相信这是我的问题所在：
// tabNamer creates the active & default textfields
tabNamer(tabNameActive, Fonts.ActiveTabText, tabData[0].id); // for ActiveTab
tabNamer(tabNameDefault, Fonts.DefaultTabText, tabData[i].id); // for DefaultTabs
tabNamer是一个只包含一个 textField 的函数，我相信我一直在覆盖最后一个 textField，这就是为什么只有第 4 个也是最后一个 textField 显示文本的原因。有没有办法动态命名我的 textFeilds 是我循环吗？

这些是来自创建选项卡功能（类功能）的痕迹
i = 0
tabArray[0].getChildAt(2) = This is first tab
tabNameDefault.text = This is first tab
i = 1
tabArray[1].getChildAt(2) = 2nd Tab
tabNameDefault.text = 2nd Tab
i = 2
tabArray[2].getChildAt(2) = The 3rd Tab
tabNameDefault.text = The 3rd Tab
i = 3
tabArray[3].getChildAt(2) = The 4th and last tab
tabNameDefault.text = The 4th and last tab
这些是我单击选项卡时得到的痕迹（我试图找到第二个和第三个文本字段）
//Clicked Tab 1
Text for button clicked: This is first tab
//Clicked Tab 2

一整天都在为此绞尽脑汁:(希望得到任何建议、提示或伙计，这就是为什么！:)
