如何使用androids LayoutInflater.Factory创建自定义视图类而不是内置类？

Question

我正在使用基于RelativeLayout的自定义类，但它显然不会在Eclipse布局编辑器中呈现。

我发现这篇文章关于LayoutInflater.Factory，它听起来像我需要做的，但我找不到使用LayoutInflater.Factory的指南。

谁能有什么，我做的这个地方帮助？我理解这篇文章中所说的内容，但需要具体说明在哪里申报，钩住什么工厂。

如果它是有帮助的，下面是当我尝试查看版式视图main.xml中输出的完整的控制台..

Answer 1

LayoutInflater.Factory是不是你想要的。 Eclipse编辑器完全能够显示自定义视图，您应该检查错误日志以防发生错误。

Answer 2

发现问题。这不是一个铸造这个对象的问题，而是它内部的另一个ViewGroup，它被视为代码中的View。
