【中文标题】Android 应用无法在某些设备上运行【英文标题】：Android app won't work in some of the devices 【发布时间】：2017-05-10 08:15:29 【问题描述】：我创建了一个显示 Firebase 子级的应用。它可以在我的手机（nexus 6）中运行，也可以在另一个（一加 3）中运行，但是当我将它安装在其他设备（如 redmi note 3）中时，应用程序强制关闭，我不确定为什么会发生这种情况。

这是卡片视图布局，其中没有按钮，因为我昨天删除了按钮并使用 ImageViews 进行了更新

【问题讨论】：
您正在尝试将 ImageView 转换为 Button 从您的错误中可以看出。贴出相关代码 @KostasDrak 我已经用代码更新了问题，我没有按钮。 代码看起来不错，干净，重新构建然后再次在小米上运行...... @MuhammadFaisalHyder 谢谢，我重新构建了代码，它现在可以工作，一个小问题，我如何将其标记为答案，这个社区的新手。 很高兴为您提供帮助，我在下面发布了一个答案，您可以接受它:) cmets 不能被接受为答案。 【参考方案1】：有时，IDE 中会出现问题，即它们会弄乱分配的 ID，并且在某些情况下需要重建、清理甚至使缓存无效并重新启动项目需要。在这种情况下，代码看起来还可以，干净，重新构建，然后再次在小米上运行您的应用程序。
