当我在真实设备中打开活动时应用程序崩溃

Posted 2023-02-24

【中文标题】当我在真实设备中打开活动时应用程序崩溃

【英文标题】：App crashes when i open the activity in real device

【发布时间】：2017-09-10 17:08:26

【问题描述】：

我认为问题在于 xml 文件。应用程序在模拟器中运行良好，但在我尝试打开另一个活动时在真实设备上崩溃。下面是我的 xml 和 logcat。我正在从 firebase 检索数据，但是当我打开这个活动时，它只在手机上崩溃，但在模拟器上工作正常。下面的设计视图显示未能实例化一个或多个类。

【问题讨论】：

在 FoodDetail.java:34，你是如何放大视图的？

@AndrewChiLam 我也用 java 代码编辑了我的问题

，检查库导入是否正确

编译'com.cepheuen.elegant-number-button:lib:1.0.2'

@AndrewChiLam 先生，我已经编辑了我的 logcat 错误

【参考方案1】：

而不是这个

android:backgroundTint="@android:color/white"

写这个

app:backgroundTint="@android:color/white"
