注意：代码在5.0 OS中运行良好，但在6.0＆amp; 7.0它会产生问题。 请让我知道为什么我会遇到这个问题。
答案 0 :(得分：1)
问题是你已经为OS 5.0上的特定设备制作了特定的应用，这显然是非触摸的。现在在Touch设备上，按钮和复选框的大小要大得多，而您却试图将它们限制为更小的尺寸。所以复选框通常会占用你所做的任何内容，但是当聚焦时，他们会尝试为自己腾出空间，这会干扰你的屏幕布局。删除复选框中的人为约束，您的直接问题可能会得到解决。
但是，此代码中存在许多问题，可能会在以后引发问题。
使用Screen.USE_ALL_HEIGHT不会影响整个显示。
你不必要地覆盖每一个领域以某种方式约束他们的身高。而你做错了。例如，在iaDescriptionEditField中，您已为布局提供了全宽，但随后限制了其大小。这将导致该字段未在末端绘制。
您拥有硬编码的宽度和高度 - 包括以像素为单位的字体，这会使您的应用在高像素密度设备（如粗体3）上看起来非常糟糕。
您正在覆盖HorizontalFieldManager，然后完全重新创建sublayout方法。最好只是扩展Manager类，因为您似乎没有使用HorizontalFieldManager的任何工具。
请记住，并非所有字段都会提供正确的getPreferredWidth / Height，您应该只使用这些方法在布局过程中进行估算。
我建议您在考虑到您需要定位的不同设备后重新考虑并重写整个代码。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。
