浏览数：37 /
时间：2015年06月11日
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
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>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);

courseData[0]=list1;

list3.add(new Course("电影赏析", "A112", 9, 2, "诸葛亮", "1039"));
courseData[2]=list3;

}
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){
lp.setMargins(marLeft, (c.getStart()-(pre.getStart()+pre.getStep()))*(itemHeight+marTop)+marTop, 0, 0);
}else{
lp.setMargins(marLeft, (c.getStart()-1)*(itemHeight+marTop)+marTop, 0, 0);
}
tv.setLayoutParams(lp);
tv.setGravity(Gravity.TOP);
tv.setGravity(Gravity.CENTER_HORIZONTAL);
tv.setTextSize(12);
tv.setTextColor(getResources().getColor(R.color.courseTextColor));
tv.setText(c.getName()+"\n"+c.getRoom()+"\n"+c.getTeach());
//tv.setBackgroundColor(getResources().getColor(R.color.classIndex));
tv.setBackground(getResources().getDrawable(R.drawable.tvshape));
ll.addView(tv);
pre=c;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
