无法解析符号 Theme.MaterialComponents.Light.NoActionBar (Android Studio)

我有一个错误'Theme.MaterialComponents.Light.NoActionBar' in styles.xml (the 'Theme.MaterialComponents.Light.NoActionBar'由于错误而变成红色）在几次 gradle 更新后。我的组件也没有按照我的设计理念很好地排列。

我已经清理并重建项目，使缓存/重新启动无效，更新 gradle（可能不是正确的答案），但没有答案。我只是想也许我是唯一一个遇到这个问题的人，也许是我的初学者问题:')

样式.xml

`

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/hitam</item>
    <item name="colorAccent">@color/colorAccent</item>

</style>

我希望当这个地球上没有人出现此错误时，该错误是不可见的。请帮忙T_T

The 材质组件主题 https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md#material-components-themes都包含在Android 库的 Material 组件 https://github.com/material-components/material-components-android.

由于您使用的是 androidx 库，只需在您中添加此依赖项app/build.gradle file.

dependencies {
    // ...
    implementation 'com.google.android.material:material:x.x.x'
    // ...
  }

目前（2022年4月29日）最新稳定版本是

implementation 'com.google.android.material:material:1.5.0'
