Android 选择器显示错误

Question

在我的 android xml 文件中，我有一个 edittext。我试图自定义 edittext，xml 看起来像:--

 <EditText
            android:id="@+id/edi"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ems="10"
            android:layout_marginTop="10dp"
            android:layout_gravity="center"
            android:hint="Username"
            android:background="@layout/textbox001"
            android:drawableLeft="@drawable/usernameicon"
          / >

在布局中，textbox001 是:--

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <item android:state_pressed="true" >
        <shape>
            <gradient
                android:startColor="#e4e4e2"
                android:endColor="#d5d5d5"
                android:angle="270" />
            <stroke
                android:width="0dp"
                android:color="#282a2f" />
            <corners
                android:topLeftRadius="10dp"
        android:topRightRadius="10dp"
        android:bottomLeftRadius="0dp"
        android:bottomRightRadius="0dp" />
            <padding
                android:left="10dp"
                android:top="10dp"
                android:right="10dp"
                android:bottom="10dp" />
        </shape>
    </item>
    <item>
        <shape>
            <gradient
        android:endColor="#e4e4e2"
        android:startColor="#d5d5d5"
        android:angle="270"
 />
            <stroke
                android:width="0dp"
                android:color="#282a2f" />
            <corners
                android:topLeftRadius="10dp"
        android:topRightRadius="10dp"
        android:bottomLeftRadius="0dp"
        android:bottomRightRadius="0dp" />
            <padding
                android:left="10dp"
                android:top="10dp"
                android:right="10dp"
                android:bottom="10dp" />

        </shape>
    </item>
</selector>

但它在选择器中显示错误..即:--

element selector does not have  required attribute android:layout_width 
element selector does not have  required attribute android:layout_height

问题出在哪里？？？我该如何解决？？在 xml 图形中，它还显示:--

The graphics preview in the layout editor may not be accurate:
Different corner sizes are not supported in Path.addRoundRect. (Ignore for this session)

我认为您应该将选择器文件放在可绘制文件夹中，而不是布局文件夹中!
