Android 如何更改材质文本InputLayout OutlineBox未聚焦颜色

我有一个OutlinedBox TextInputLayout，我想在editText的非聚焦模式下更改框的颜色

我该怎么做

---

在主题中添加

colorOnSurface

属性并指定所需的任何颜色

<style name="Apptheme"
       parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- General theme colors -->
    <item name="colorPrimary">@color/material_green_500</item>
    <item name="colorSecondary">@color/material_green_600</item>
    <item name="colorAccent">@color/illiniColorAccent</item>

    <item name="colorOnSurface">@color/blue</item><!--inputtext unfocused color-->
</style>

你好，Morteza Rastgoo，不存在这样的属性，这是Android Studio显示的错误。你能帮我解决这个问题吗？@parekhkruti26确保你扩展了Hello Morteza，我扩展了与你所说的相同的主题，但问题是，我使用了材质库的最后一个稳定版本，即

1.0.0

，我想这个属性是该库最新alpha版本的一部分。
