注：该代码是在5.0的操作系统工作正常，但在6.0 & 7.0它创造的问题。请让我知道为什么我得到这个问题。

请访问[本站]（http://sscce.org/）。绝对没有必要在这里发布这么多的代码。 – Nate 2013-04-11 09:53:28

hello @Nate ..我会照顾，你能告诉我为什么我的屏幕得到减少后，每次点击dateSelection管理器，在insertDateSelectionManager（）方法，当我评论setchangelistenr它工作正常.. – 2013-04-11 10:56:23

问题在于，您已经针对OS 5.0上的某个特定设备制定了特定的应用程序，该应用程序显然没有触摸。现在在触控设备上，按钮和复选框的尺寸要大得多，而您试图将它们限制为更小的尺寸。所以复选框通常会采取你已经完成的任何事情，但是当它们集中时，它们会尝试为自己腾出空间，这会干扰你的屏幕布局。删除复选框中的人工约束，您的直接问题可能会得到解决。

但是，此代码中存在很多问题，可能会在稍后引发问题。

使用Screen.USE_ALL_HEIGHT不会占用整个显示屏。
您不必要地覆盖每个领域，以某种方式限制他们的身高。你做错了。例如，在iaDescriptionEditField中，您已为布局给出了完整宽度，但随后限制了其大小。这将导致该字段在末尾处未被绘制。
你硬编码的宽度和高度 - 包括以像素为单位的字体，这将使你的应用程序看起来很糟糕的高像素密度的设备，如大胆3.
要覆盖一个HorizontalFieldManager然后完全重建子布局方法。最好只扩展Manager类，因为您似乎没有使用任何HorizontalFieldManager工具。
请记住，并非所有字段都会给出正确的getPreferredWidth/Height，并且您应该只使用这些方法在布局期间进行估计。

我建议您在考虑到需要定位的不同设备后重新考虑并重新编写整个代码。使用基于点的字体和测量，而不是基于像素的测量。

一切顺利。

@adwin感谢您的答复据我所知，罪魁祸首部分是r1，r2，r3 setchangelistener部分..当我评论代码时屏幕可能不会减少，并且每件事情都可以正常工作，但根据应用程序的要求，一次只能选择一个复选框..我必须禁用其他 – 2013-04-12 05:55:21

如果我不使用nonProgrammaticChange（）..然后我得到堆栈溢出异常..有没有其他方法来解决问题 – 2013-04-12 08:51:36

@Mario你的setChangeListeners做了很多事情包括检查/取消选中和设置标签字段。试着通过评论来找出代码的哪个部分正在做这件事。 – adwiv 2013-04-12 09:48:56

点击复选框后屏幕高度降低
