Derek Banas教程：未找到类“android.view.button”

时间：2014-06-28 19:43:30

标签： android eclipse logcat

我目前正在关注Derek Banas的教程1（网址：http://www.youtube.com/watch?v=Z149x12sXsw） 我在日志猫中显示了一些错误。基本上，有一个关于片段xml的已知问题，我已经解决了它。问题是当我的项目没有错误（没有x或！符号）时，每当我运行时，应用程序都会在我的eclipse虚拟设备上停止。

这是我的logcat：

答案 0 :(得分：4)

在布局xml文件中，使用Button代替button。

答案 1 :(得分：0)

您正在对主要活动布局进行膨胀，但由于无法找到类android.view.button，因此失败了。

你的布局（xml）可能包含一个标记<button>，这是错误的：将其更改为<Button>
