自定义的登录布局 : login.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:id="@+id/loginLayout">    <LinearLayout android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="horizontal">        <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"        android:text="用户名"         />    <EditText android:layout_width="match_parent" android:layout_height="wrap_content"/>    </LinearLayout>      <LinearLayout android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="horizontal">        <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"        android:text="密码"         />    <EditText android:layout_width="match_parent" android:layout_height="wrap_content"/>    </LinearLayout></LinearLayout>

选项的资源文件：

<?xml version="1.0" encoding="utf-8"?><resources>    <string-array name="stulist">        <item>黄晓明</item>        <item>朱莉</item>        <item>李菲菲</item>        <item>李小名</item>        <item>李雪</item>    </string-array></resources>
