我正在尝试修改我的布局，但每当我使用图形布局时，它最终都会中断并给出如下所示的错误。我知道这不是问题，因为当我撤消更改时它会起作用。只有当我使用图形布局时。如果我使用 XML 它工作得很好。我知道它说它在我的 java 代码中，但切换 xml 布局不应导致此错误。第 294 行是 mEnergy = (ImageButton) view.findViewById(R.id.btnEnergy);

Best Answer-推荐答案


清理您的项目。在 Eclipse 中，

Project -->Clean... choose your project

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可以解决此类错误。在拔出所有头发试图弄清楚为什么会出现这种异常之前，这是一件快速而简单的事情。

另外，我建议尽可能使用 xml 选项卡。恕我直言，它更灵活，更容易获得您想要的结果。手动编码 xml 时仍然会遇到此问题，但我认为大多数时候以这种方式生成所需的布局更容易。

关于android - 布局更改导致崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17529535/
