java - 二进制 XML 文件行 #21 : Binary XML file line #21: Error inflating class com. google.android.material.textfield.TextInputLayout

Question

当我的应用崩溃时，我在实现 TextInputLayout 时遇到问题。

我使用下面的 XML 创建了一个 UI:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:focusableInTouchMode="true"
        android:padding="16dp">

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="20dp"
            android:scaleType="centerCrop" />

        <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Card number" />

        </com.google.android.material.textfield.TextInputLayout>


        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#53BD55"
            android:onClick="pay"
            android:text="Make Payment"
            android:textColor="#FFFFFF" />

    </LinearLayout>
</LinearLayout>

并将这一行添加到我的依赖项中:

implementation 'com.google.android.material:material:1.0.0-beta01'

但我的应用程序仍然崩溃，错误堆栈跟踪如下:

请问这可能是什么问题？

只需检查您的应用主题，如果没有，请将其设置为 @style/Theme.MaterialComponents.Light。

希望它对您有用!
