InflateException 膨胀 class EditText 时出错

Question

我在 Android Studio 上充气时遇到问题。

它在模拟器中运行良好。然而，我在 phone（HTC One M7 - 第一个）上测试了应用程序。

有人知道这个的解决方案吗？

布局如下：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:weightSum="1">

    <android.support.v7.widget.CardView
        android:id="@+id/ingcard"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        android:layout_marginLeft="4dp"
        android:layout_marginRight="4dp"
        card_view:cardElevation="10dp"
        card_view:cardPreventCornerOverlap="true"
        card_view:contentPadding="5dp">

        <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="match_parent">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceLarge"
                android:text="Medium Text"
                android:id="@+id/tvrecname"
                android:layout_alignParentLeft="true"
                android:layout_alignParentTop="true" />

            <EditText
                android:layout_width="100dp"
                android:layout_height="wrap_content"
                android:inputType="numberDecimal"
                android:ems="10"
                android:id="@+id/etingquantity"
                android:layout_alignParentEnd="true"
                android:layout_alignParentRight="true" />
        </RelativeLayout>
    </android.support.v7.widget.CardView>
</FrameLayout>
