Binary XML file line #21: Binary XML file line #21: Error inflating class com.google.android.material.textfield.TextInputLayout

Question

當我的應用程序崩潰時，我在實現TextInputLayout時遇到問題。

我使用下面的 XML 創建了一個 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>

並將這一行添加到我的依賴項中：

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

但我的應用程序仍然崩潰並出現以下錯誤堆棧跟蹤：

請問可能是什么問題？

Answer 1

只需檢查您的 App Theme 並將其設置為@style/Theme.MaterialComponents.Light如果不是。

希望這對你有用！
