Android:XML 文件中的哪些部分在长按 View 时导致 InflateException

Question

这是我正在努力解决的问题的屏幕。

屏幕中央的白框是两个EditText。简单地单击 EditText 时没有问题，但是如果我长按它们，应用程序会报错退出，并在日志中留下以下异常。

android.view.InflateException: Binary XML file line #17: Error inflating class <unknown>

我认为这是由于此 Activity 中使用的 XML 文件的一些误导属性所致。

这是包含两个 EditText 的布局。

<RelativeLayout
    android:id="@+id/rlLoginBox"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:visibility="invisible">

    <EditText
        android:id="@+id/etEmail"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="15dp"
        android:background="@drawable/login_box_top"/>

    <EditText
        android:id="@+id/etPassword"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/etEmail"
        android:padding="15dp"
        android:background="@drawable/login_box_bottom"/>

</RelativeLayout>

如您所见，每个 EditText 都引用其各自的可绘制文件，称为 login_box_top.xml 和 login_box_bottom.xml。

login_box_top.xml文件如下。

<?xml version="1.0" encoding="utf-8"?>
<inset android:insetBottom="-2px" xmlns:android="http://schemas.android.com/apk/res/android">
    <selector>
        <item android:state_pressed="true">
            <shape android:shape="rectangle">
                <corners  android:topLeftRadius="4dip"
                    android:topRightRadius="4dip"
                    android:bottomLeftRadius="0dip"
                    android:bottomRightRadius="0dip" />
                <stroke android:width="2px" android:color="#E6E6E6" />
            </shape>
        </item>
        <item>
            <shape android:shape="rectangle">
                <corners  android:topLeftRadius="4dip"
                    android:topRightRadius="4dip"
                    android:bottomLeftRadius="0dip"
                    android:bottomRightRadius="0dip" />
                <solid android:color="#FFFFFFFF" />
                <stroke android:width="2px" android:color="#E6E6E6" />
            </shape>
        </item>
    </selector>
</inset>

这是 login_box_bottom.xml 文件。

<?xml version="1.0" encoding="utf-8"?>
<inset android:insetTop="-1px" xmlns:android="http://schemas.android.com/apk/res/android">
    <selector>
        <item android:state_pressed="true">
            <shape android:shape="rectangle">
                <corners
                    android:bottomLeftRadius="4dip"
                    android:bottomRightRadius="4dip"
                    android:topLeftRadius="0dip"
                    android:topRightRadius="0dip"  />
