我不明白问题是什么？我是android开发新手，我不理解任何错误信息。请帮我解决这个问题！当我尝试运行时，应用程序正在崩溃！我已经在顶部给出了我的代码示例和错误消息

更换

<LinearLayoutCompat
            android:layout_width="match_parent"
            android:layout_height="match_parent"

这是LinearLayoutCompat的通货膨胀例外。找不到类。试试线性布局吧！显示您的build.gradle，其中添加了dependenciesThanks…您的建议对我有用。。。。。
