1. 效果图
   
   
   自定义课程显示图
2. 自布局文件
   1）左上角的布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="50dip" android:layout_height="50dip" >

    <TextView  android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:textColor="#FF0000" android:text="课程表" />

</RelativeLayout>

2）上边的布局文件，星期几

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="100dip" android:layout_height="50dip" >

    <TextView  android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:textColor="#FF0000" android:text="星期几" />

</RelativeLayout>

3）课时的布局，例如1-2

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="50dip" android:layout_height="100dip" >

    <TextView  android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:textColor="#FF0000" android:text="1-2" />

</RelativeLayout>

4）课的详细信息的布局文件，

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="50dip" android:layout_height="100dip" >

    <TextView  android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:textColor="#FF0000" android:text="1-2" />

</RelativeLayout>

1. 自定义的CourseView，继承自ViewGroup，可以滑动！，支持横竖屏切换时数据的保存与恢复。
   实体类
