我正在为 RecyclerView 项目使用围绕 EditText 的 TextInputLayout。我正在使用样式“Theme.AppCompat.Light.NoActionBar”。但我仍然收到错误 “Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.AppCompat (or a descendant).” 但是，当我从 xml 中删除 TextInputLayout 时，应用程序运行正常。
这是我的 RecyclerView 项目 (item_content_settings):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="20">
<com.google.android.material.textfield.TextInputLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="18"
android:padding="16dp">
<EditText
android:id="@+id/content_summary"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:hint="First Name"
android:inputType="text"
android:text="First Name And Last Name" />
</com.google.android.material.textfield.TextInputLayout>
<ImageView
android:id="@+id/pencil"
android:layout_width="0dp"
android:layout_height="16dp"
android:layout_gravity="center"
android:layout_margin="0dp"
android:layout_weight="2"
android:src="@drawable/pencil_edit" />
</LinearLayout>
我的风格:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="AppTheme.Base">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<!--
Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.
-->
</style>
<!-- <style name="AppTheme.NoActionBar">-->
<!-- <item name="windowActionBar">false</item>-->
<!-- <item name="windowNoTitle">true</item>-->
<!-- </style>-->
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/background</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
安卓 list :

最佳答案
作为@MikeM。评论了用于实例化 Adapter 的上下文存在问题的问题。
您需要传递 Activity，而不是 Application Context。
ApplicationContext 没有您的应用主题。
但请注意，因为您使用的是 com.google.android.material.textfield.TextInputLayout，检查 the doc Material 组件库。
您的应用主题应继承自 Material Components theme .
如果您无法更改主题，您可以执行以下操作之一:
- 继承 self 们的
Material Components Bridge之一主题。 - 继续继承
AppCompat主题并添加一些new theme attributes到你的主题。
关于android - TextInputLayout 抛出 "The style on this component requires your app theme to be Theme.AppCompat (or a descendant)."，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58007372/
