文章标题

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。

1. actiivty的布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent">    <com.course.csh.view.CourseView        android:id="@+id/courseView1"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_centerHorizontal="true"        android:layout_centerVertical="true" >    </com.course.csh.view.CourseView></RelativeLayout>

1. Activity文件！

package com.course.csh;import android.os.Bundle;import android.app.Activity;import android.view.Menu;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }}
