Android 标签页和意图
我有一个自动完成文本框，用户可以在其中进行选择。从这里我想加载一个基于用户选择的选项卡式布局。问题是我无法找到一种干净的方法将该选择传递给每个选项卡。目前，我可以将意图传递给“tabhost”活动，然后显式传递给每个子活动，但是对我来说，这似乎是混乱的迭代代码！所以基本上我怎样才能将我的意图数据包干净地传递到选项卡活动？高效！伪代码也非常受欢迎;)
干杯伙计们
I have a auto-complete textbox in which the user makes a selection. From here I want to load a tabbed layout which is based on the user selection. The problem is I cant figure out a clean way to pass that selection to each of the tabs. At the moment I can pass an intent to the 'tabhost' activity and then pass to each child activity explicitly, however this just seems like messy iterative code to me! So basically how can I pass my intent data bundles to the tabs activities cleanly & efficiently! Psuedo code is also very welcome ;)
Cheers guys

您可以将选择存储为 SharedPreference，然后从任何活动中获取值。想到的第二个选项是将所选值保存在应用程序上下文中，也可以从任何活动轻松访问该值。
You can store the selection as SharedPreference and then just obtain the value from any activity. Second option that comes in mind is saving the selected value on the Application context which is also easily accessible from any activity.
