这里是 styles.xml

<resources>

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

这是堆栈跟踪

我尝试将 AppCompat 更改为 MaterialComponents，但它不起作用。但是当我指向 LinearLayout 标签(com.google.android.material.textfield.TextInputLayout 的父级)时，它会用红线显示错误，当我移除 LinearLayout 标签时它会消失。当我使用太多 LinearLayout 相互堆叠时会出现问题吗？

Answer 1

确保在你的应用级 build.gradle 文件中添加 Material 依赖并改变

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

到

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
