Android布局翻转/翻转在logcat中显示错误

【问题标题】：Android layout flip/turn showing errors in logcatAndroid布局翻转/翻转在logcat中显示错误
【发布时间】：2011-04-26 07:05:39
【问题描述】：

我是安卓新手。在谷歌搜索了一下后，我尝试了一个动画程序并在模拟器中强制关闭，并且在运行项目时没有显示任何东西

我想为两个布局（xml 文件）（即 signin.xml 和 register.xml）设置翻转/翻转效果。通过单击 signin.xml 中的新用户按钮，我想将布局转换为 register.xml

我采用了两种布局并尝试实现，即线性和表格布局。我遵循的程序是否正确

我添加了单个按钮进行试用，但它不起作用，我想知道这段代码有什么问题

我没有收到任何错误，但运行时模拟器出现问题。

请有人帮助我，...谢谢！

这些是我的 xml 文件

    【解决方案1】：

    我已经检查了您在模拟器上的代码，并且现在可以正常工作。您必须首先在flip3d.java 中更改包含的布局名称

    setContentView(R.id.flip); //currenlty its R.id.main

    然后你将 main.xml 和 register.xml 的实际布局内容复制到flip.xml itslef 中，而不是使用include 标签包含它们。模拟器似乎无法以这种方式处理布局包含。
