我正在尝试修改我的布局，但每当我使用图形布局时，它最终会破坏并在下面看到错误。我知道这不是问题，因为它可以解除我的更改。只有在我使用图形布局时才会这样。如果我使用XML它就可以正常工作。我知道它说它在我的java代码中，但切换xml布局不应该导致此错误。第294行是mEnergy = (ImageButton) view.findViewById(R.id.btnEnergy);

答案 0 :(得分：10)
清理您的项目。在Eclipse中，
项目 - ＆gt;清理......选择项目
有时Eclipse不会立即获取xml更改，因此它会抛出这些类转换异常。简单地清理和重建项目通常会处理这些错误。这是一个快速简单的事情，在拉出你所有的头发之前试图弄清楚为什么你会得到这样的例外。
另外，我建议尽可能使用xml选项卡。恕我直言，它更灵活，更容易得到你想要的结果。在手动编写xml代码时仍然会遇到此问题，但我认为在大多数情况下以这种方式生成所需的布局会更容易。
答案 1 :(得分：0)
您的布局xml文件错误。
不是android:layout_alignBottom="@+id/btnEnergy"，android:layout_alignBottom="@id/btnEnergy"不包括“+”
@ + id表示添加新ID，这会导致错误。
