Android动态生成课程表 详解

根据提供的课程信息,动态生成课程表。不同于网上流传的课表形式,课程节数是固定,本课表的课程节数不固定。

1、效果图

技术分享技术分享

每天共有12节课,上课节数每天都不同。

2、布局文件代码

周一到周日是  7个竖直线性布局文件,其他皆为辅助标题或序号。

<LinearLayout 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"

	     	        />
	     	</LinearLayout>
	        <!-- 周一到周日的排列 -->
	     	<LinearLayout 
	     	    android:id="@+id/weekPanel_1"
	     	    android:layout_width="0dp"
	     	    android:layout_height="wrap_content"
	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	     	<LinearLayout 
	     	    android:id="@+id/weekPanel_2"
	     	    android:layout_width="0dp"
	     	    android:layout_height="wrap_content"
	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	     	<LinearLayout

	     	    android:layout_height="wrap_content"
	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	     	<LinearLayout 
	     	    android:id="@+id/weekPanel_4"
	     	    android:layout_width="0dp"
	     	    android:layout_height="wrap_content"
	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	     	<LinearLayout 
	     	    android:id="@+id/weekPanel_5"
	     	    android:layout_width="0dp"
	     	    android:layout_height="wrap_content"
	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	     	<LinearLayout

	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	     	<LinearLayout

	     	    android:layout_weight="1.0"
	     	    android:orientation="vertical"
	     	    >
	     	    
	     	</LinearLayout>
	    </LinearLayout>
	</ScrollView>
</LinearLayout>
3、布局文件中用到的尺寸文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="weekItemHeight">40dp</dimen>
    <dimen name="weekItemMarTop">2dp</dimen>
    <dimen name="weekItemMarLeft">2dp</dimen>
    
</resources>
4、颜色文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="classIndex" >#CCCCCC</color>
    <color name="courseTextColor" >#ECECEC</color>
    <color name="actionBarBg">#6666CC</color>
    <color name="actionBarText">#EDEDED</color>
</resources>
5、样式文件

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="AppBaseTheme" parent="android:Theme.Light">
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:actionBarStyle">@style/myActionBarStyle</item>
    </style>
    
    <style name="myActionBarStyle" parent="android:Widget.ActionBar" >
      <item name="android:background">@color/actionBarBg</item>
      <item name="android:titleTextStyle">@style/myActionBarTextStyle</item>
      <item name="android:height">40dp</item>
    </style>
	<style name="myActionBarTextStyle">
		<item name="android:textSize">18sp</item>	
		<item name="android:textStyle">bold</item>    
		<item name="android:textColor">@color/actionBarText</item>	    
	</style>
    
</resources>

6、课程实体类代码

package com.example.testcourse;

public class Course {
	private String name,room,teach,id;//课程名称、上课教室,教师,课程编号
	int start,step;	//开始上课节次, 一共几节课
	public Course(String name, String room, int start, int step,
			String teach, String id) {
		super();
		this.name = name;
		this.room = room;
		this.start = start;
		this.step = step;
		this.teach = teach;
		this.id = id;
	}

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getRoom() {
		return room;
	}

	public void setRoom(String room) {
		this.room = room;
	}

	public int getStart() {
		return start;
	}

	public void setStart(int start) {
		this.start = start;
	}

	public int getStep() {
		return step;
	}

	public void setStep(int step) {
		this.step = step;
	}

	public String getTeach() {
		return teach;
	}

	public void setTeach(String teach) {
		this.teach = teach;
	}
	
	
}

7、Activity代码,只要提供7天课程信息,课表可以自动生成。

package com.example.testcourse;

import java.util.ArrayList;
import java.util.List;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Color;
import android.text.Layout;
import android.util.Log;
import android.view.Gravity;
import android.view.Menu;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {
	LinearLayout weekPanels[]=new LinearLayout[7];
	List courseData[]=new ArrayList[7];
	int itemHeight;
	int marTop,marLeft;
	
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //
        itemHeight=getResources().getDimensionPixelSize(R.dimen.weekItemHeight);
        marTop=getResources().getDimensionPixelSize(R.dimen.weekItemMarTop);
        marLeft=getResources().getDimensionPixelSize(R.dimen.weekItemMarLeft);
        
        //数据
        getData();
        
        for (int i = 0; i < weekPanels.length; i++) {
			weekPanels[i]=(LinearLayout) findViewById(R.id.weekPanel_1+i);
			initWeekPanel(weekPanels[i], courseData[i]);
		}
        
    }
    public void getData(){
    	List<Course>list1=new ArrayList<Course>();
    	Course c1 =new Course("软件工程","A402", 1, 4, "典韦", "1002");
    	list1.add(c1);
    	list1.add(new Course("C语言", "A101", 6, 3, "甘宁", "1001"));
    	courseData[0]=list1;

    	List<Course>list2=new ArrayList<Course>();
    	list2.add(new Course("计算机组成原理", "A106", 6, 3, "马超", "1001"));
    	courseData[1]=list2;
    	
    	List<Course>list3=new ArrayList<Course>();
    	list3.add(new Course("数据库原理", "A105", 2, 3, "孙权", "1008"));
    	list3.add(new Course("计算机网络", "A405", 6, 2, "司马懿", "1009"));
    	list3.add(new Course("电影赏析", "A112", 9, 2, "诸葛亮", "1039"));
    	courseData[2]=list3;
    	
    	List<Course>list4=new ArrayList<Course>();
    	list4.add(new Course("数据结构", "A223", 1, 3, "刘备", "1012"));
    	list4.add(new Course("操作系统", "A405", 6, 3, "曹操", "1014"));
    	courseData[3]=list4;
    	
    	List<Course>list5=new ArrayList<Course>();
    	list5.add(new Course("Android开发","C120",1,4,"黄盖","1250"));
    	list5.add(new Course("游戏设计原理","C120",8,4,"陆逊","1251"));
    	courseData[4]=list5;
    }
    
    public void initWeekPanel(LinearLayout ll,List<Course>data){
    	if(ll==null || data==null || data.size()<1)return;
    	Log.i("Msg", "初始化面板");
    	Course pre=data.get(0);
    	for (int i = 0; i < data.size(); i++) {
			Course c =data.get(i);
			TextView tv =new TextView(this);
			LinearLayout.LayoutParams lp =new LinearLayout.LayoutParams(
					LinearLayout.LayoutParams.FILL_PARENT ,
					itemHeight*c.getStep()+marTop*(c.getStep()-1));
			if(i>0){
