添加按钮时应用崩溃-Android

Question

我在android应用程序设计方面绝对有0经验。我的一个朋友要我尝试为他们的应用创建功能，这就是我过去一周一直在尝试的功能。我需要做的前几件事是添加背景图像（完成），添加文本（完成）并添加按钮，该按钮调出菜单（问题）。无需添加按钮，我可以在Android Studio的内置仿真器中运行该应用程序，但是当我添加按钮/ imageButton时，该应用程序将崩溃。在这一点上，我什至没有想过要调出菜单的按钮，那是另一天。我要做的就是让按钮不会崩溃的应用程序。我一直在互联网上寻找教程，文档，甚至在堆栈溢出的地方，但是我什么也找不到。

现在，我什至尚未开始使用Java代码，而仅使用XML代码（请参见下文）。我将发布错误消息（来自android监视器功能的错误消息），并将发布我的设备在工作室中的外观以及在模拟器上显示的消息的图像。如果有人可以帮助我，我将非常感激。

Answer 1

您是如何导入图像的？在Android Studio中使用图像资产（在Res目录中右键单击并选择图像资产），将根据需要正确生成图像
