一个Android自动生成课程表的自定义控件
CSDN:http://blog.csdn.net/hmyang314/article/details/52076392
##一、介绍 1、根据传入课程数据,或日期数据、时间数据,动态显示课程表; 2、顶部日期行的显示样式可以自定义,空课程、课程的内容及背景也可自定义; 3、第一列,及时间列的宽度可以设置,默认为0,则宽度与课程格子的宽度相同,内容与背景也可以自定义; 4、当课程页面超出手机屏幕高度时,可以上下滑动,改变数据可刷新控件就可以更新界面;
##二、使用方法
1、核心类是CourseTableLayout,继承自LinearLayout的抽象类,所以我们实际项目使用需要继承它,这里使用了泛型,试课程表使用更加灵活,并要实现对应的抽象方法,如下:
public abstract class CourseTableLayout<T> extends LinearLayout {
//******************************其他代码省略**************************
/**
* 判断该课程是否是当前时间的课程
*
* @param course
* @param dayPosition
* @param timePosition
* @return 返回boolean 数组长度为2,
* boolean[0]:true 代表该课程是当前时间点的课程,boolean[1]:true 代表当前时间点是上面的连续课程
*/
protected abstract boolean[] compareToCourse(T course, int dayPosition, int timePosition);
/**
* 对左上角第一个TextView自定义显示
*
* @param firstTextView
*/
protected void showFirstTextView(TextView firstTextView) {
}
/**
* 显示空课程(默认文本已显示,这里用于自定义效果)
*/
protected void showEmptyCourse(TextView textView, int dayPosition, int timePosition, int oneTableWidth, int oneTableHeight) {
}
/**
* 显示课程到控件,并且需要根据课程节数改变控件高度
*
* @param textView
* @param course 课程数据
* @param oneTableWidth 一个课程控件宽度
* @param oneTableHeight 一个课程控件高度
*/
protected abstract void showCourse(TextView textView, T course, int dataPosition, int dayPosition, int timePosition, int oneTableWidth, int oneTableHeight);
/**
* 自定义日期文本
*
* @param textView
* @param dayPosition
* @param dayLabel
*/
protected void customDayText(TextView textView, int dayPosition, String dayLabel) {
}
/**
* 自定义时间文本
*
* @param textView
* @param timePosition
* @param timeLabel
*/
protected void customTimeText(TextView textView, int timePosition, String timeLabel) {
}
protected abstract void onClickEmptyCourse(TextView textView, int dayPosition, int timePosition);
protected abstract void onClickCourse(TextView textView, T course, int dataPosition, int dayPosition, int timePosition);
}
2、我这里用courseTableTestLayout继承CourseTableLayout实现,数据模型用CourseModel实体,这个根据具体业务可灵活更改。
public class CourseModel implements Serializable {
private static final long serialVersionUID = 1L;
public int week;
public String name;
/**
* 开始上课节次
*/
public int start;
/**
* 共几节课
*/
public int step;
}
public class courseTableTestLayout extends CourseTableLayout<CourseModel> {
private int BG_COURSE[] = new int[]{R.drawable.bg_course_table_blue_selector, R.drawable.bg_course_table_green_selector,
R.drawable.bg_course_table_red_selector};
private OnClickCourseListener mOnClickCourseListener;
public courseTableTestLayout(Context context, AttributeSet attrs) {
super(context, attrs);
initData();
}
public courseTableTestLayout(Context context) {
super(context);
initData();
}
private void initData() {
setIsShowDefault(true);
}
@Override
protected boolean[] compareToCourse(CourseModel course, int dayPosition, int timePosition) {
boolean[] result = new boolean[2];
if (course.week == dayPosition + 1 && course.start == timePosition + 1) {
result[0] = true;
}
return result;
}
@Override
protected void showCourse(TextView textView, CourseModel course, int dataPosition, int dayPosition, int timePosition, int oneTableWidth, int oneTableHeight) {
textView.setBackgroundResource(R.drawable.bg_course_table_blue_selector);
}
@Override
protected void customDayText(TextView textView, int dayPosition, String dayLabel) {
}
@Override
protected void onClickEmptyCourse(TextView textView, int dayPosition, int timePosition) {
if (mOnClickCourseListener != null) {
mOnClickCourseListener.onClickEmptyCourse(textView, dayPosition, timePosition);
}
}
@Override
protected void onClickCourse(TextView textView, CourseModel course, int dataPosition, int dayPosition, int timePosition) {
if (mOnClickCourseListener != null) {
mOnClickCourseListener.onClickCourse(textView, course, dataPosition, dayPosition, timePosition);
}
}
public void setOnClickCourseListener(OnClickCourseListener listener) {
mOnClickCourseListener = listener;
}
public interface OnClickCourseListener {
void onClickCourse(TextView textView, CourseModel course, int dataPosition, int dayPosition, int timePosition);
void onClickEmptyCourse(TextView textView, int dayPosition, int timePosition);
}
}
3、在xml中实现
<com.hmy.coursetablelayout.view.CourseTableTestLayout
android:id="@+id/layout_course"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp">
</com.hmy.coursetablelayout.view.CourseTableTestLayout>
4、使用:
List<CourseModel> mList = getData();//课程数据
CourseTableTestLayout mCourseTableTestLayout = (CourseTableTestLayout) findViewById(R.id.layout_course);
//其他设置方法请在代码中查看
mCourseTableTestLayout.setData(mList);
//刷新界面这样调用
mCourseTableTestLayout.notifyDataSetChanged();
