隐藏黑莓中的一个字段
我想在屏幕上切换两个字段，就像模拟选项卡屏幕一样。我尝试创建一个 HorizontalFieldManager 并用字段 A 填充它，然后切换 deleteAll() 和 add() 字段 B。然后重复以切换它们。 （由按钮触发）这可行，但在模拟器中执行此操作五次后会被锁定。我还没有在设备上尝试过。有没有更好的方法来做到这一点，或者这几乎是做类似事情的唯一方法？
I would like to toggle two Fields on a screen, like a simulated tab screen. I tried creating a HorizontalFieldManager and populating it with Field A, then to toggle deleteAll() and add() Field B. Then Repeat to switch them. (Triggered by a button) This works, but in the simulator is locks up after doing this five times. I haven't tried it on a device yet. Is there a better way to to this, or is this pretty much the only way to do something like that?

听起来这篇支持文章涵盖了您想要做的事情： 创建选项卡式视图屏幕。不过我还没试过。
It sounds like what you want to do is covered by this support article: Create tabbed view screens. I haven't tried it though.
