我已经添加了所有必需的依赖项。
当我调试并从我的代码中删除一行时，我的应用程序不会崩溃并正常工作，我删除的行是
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
但是当我访问那里的 Material 设计页面时，我发现这个语法是正确的，但我不知道我做错了什么。
S0，请帮我解决这个错误。
发生了什么事？
MainActivity 使用 NoActionBarTheme 扩展，它没有扩展导致此崩溃的 Material 主题。
解决方案
第一步：添加material主题依赖（如果没有添加）
implementation 'com.google.android.material:material:1.3.0'
第 2 步：将您的应用主题和 Activity 主题扩展为 Material 主题。
<style name="NoActionBarTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
第 3 步：现在您可以在 TextInputLayout.
中使用 style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
您的Activity正在使用：
<style name="NoActionBarTheme" parent="Theme.AppCompat.Light.NoActionBar">
您必须切换到 MaterialComponents 主题。
