【android】项目案例(一)之超级课程表

转载请注明出处：http://blog.csdn.net/liulongling/article/details/50127819

demo和超级课程表界面和功能有些不一样 如：

 1.效果图左侧时间轴,超级课程表是每节课，我做的是每节课对应的时间

 2.每周课程切换,超级课程表是点击顶部的第几周显示每周课程，我做的是监听手指手势切换上下周

实现思路:

  1.UI上使用ScrollView来实现一天课程的滚动,因为需要实现通过手势来切换每周的课程,所以这里重写了ScrollViewExtend.否则手势监听事件会与ScrollView发生冲突

  2.布局上的划分,左边第一列是时间轴，一共24小时。除第一列,后面几列是显示课程内容.知道了每周是7天,每天24小时，屏幕宽高,求得每小时课程宽高,再深入计算每分钟的高度high。最后通过课程的时间 日期和high计算出课程显示的坐标.知道了坐标 剩下就是堆代码了...

代码运行需要配置:

 1.注解配置地址:http://jingyan.baidu.com/article/5552ef47c25fea518ffbc9e9.html

 2.注解包下载和使用地址:http://jakewharton.github.io/butterknife/

思路一代码:

1>重写ScrollView

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@drawable/bg_main"    android:orientation="vertical" >    <include        android:id="@+id/weekday"        layout="@layout/course_week_date" />    <com.app.lll.view.ScrollViewExtend        android:id="@+id/scroll_body"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_below="@+id/weekday"        android:scrollbars="none" >        <RelativeLayout            android:layout_width="match_parent"            android:layout_height="wrap_content" >            <LinearLayout                android:id="@+id/ll_weekView"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:orientation="horizontal" >                <LinearLayout                    android:id="@+id/ll_time"                    android:layout_width="50dp"                    android:layout_height="wrap_content"                    android:orientation="vertical" >                </LinearLayout>                <TextView                    android:layout_width="1.5dp"                    android:layout_height="match_parent"                    android:background="#d8d8d8" />                <RelativeLayout                    android:id="@+id/rl_courses"                    android:layout_width="match_parent"                    android:layout_height="wrap_content" >                </RelativeLayout>            </LinearLayout>            <RelativeLayout                android:id="@+id/rl_user_courses"                android:layout_width="match_parent"                android:layout_height="wrap_content" >            </RelativeLayout>        </RelativeLayout>    </com.app.lll.view.ScrollViewExtend></RelativeLayout>

package com.app.lll.view;import android.content.Context;import android.util.AttributeSet;import android.view.GestureDetector;import android.view.MotionEvent;import android.widget.ScrollView;/** * 重写ScrollView 可以与手势事件共同使用 * @author liulongling * */public class ScrollViewExtend extends ScrollView {GestureDetector gestureDetector;public ScrollViewExtend(Context context) {super(context);}public ScrollViewExtend(Context context, AttributeSet attrs) {super(context, attrs);}public ScrollViewExtend(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}public void setGestureDetector(GestureDetector gestureDetector) {this.gestureDetector = gestureDetector;}public boolean onTouchEvent(MotionEvent ev) {super.onTouchEvent(ev);return gestureDetector.onTouchEvent(ev);}public boolean dispatchTouchEvent(MotionEvent ev){gestureDetector.onTouchEvent(ev);super.dispatchTouchEvent(ev);return true;}}

2>计算课程格子高度宽度

//第一个格子宽度firstGridWidth =DensityUtils.dp2px(mContext, 50+2);//格子平均宽度aveWidth = (ScreenUtils.getScreenWidth(mContext)-firstGridWidth) / 7;//格子平均高度gridHeight =ScreenUtils.getScreenHeight(mContext) / 12;

3>左侧时间轴

<pre name="code" class="java">public void initViewParams(){if(mHourParams == null){mHourParams = new RelativeLayout.LayoutParams(firstGridWidth,gridHeight);}if(mHourTextParams == null){mHourTextParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);mHourTextParams.addRule(RelativeLayout.CENTER_HORIZONTAL);mHourTextParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);}if(mHourLineParams == null){mHourLineParams = new RelativeLayout.LayoutParams(DensityUtils.dp2px(mContext, 10),DensityUtils.dp2px(mContext, (float)1.5));mHourLineParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);mHourLineParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);}}

/** * 初始化24小时*8view */public void initTwentyFourHourViews(){initViewParams();for(int i=1;i<HOURS.length;i++){for(int j=1;j<=8;j++){if(j==1){addTimeView(i-1);//时间轴}else{addDotView(i,j-1);//小黑点//可以点击的TextView 用来添加课程TextView tx = new TextView(mContext);tx.setId((i - 1) * 7  + j);//相对布局参数RelativeLayout.LayoutParams rp = new RelativeLayout.LayoutParams(aveWidth,gridHeight);//设置他们的相对位置if(j == 2){if(i > 1){rp.addRule(RelativeLayout.BELOW, (i - 2) * 7+j);}}else{//字体样式tx.setTextAppearance(mContext, R.style.courseTableText);rp.addRule(RelativeLayout.RIGHT_OF, (i - 1) * 7  + j - 1);rp.addRule(RelativeLayout.ALIGN_TOP, (i - 1) * 7  + j - 1);tx.setText("");}tx.setLayoutParams(rp);tx.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {int hour = (v.getId()-2)/7;int weekofday=(v.getId() -1)%7;if(weekofday == 0){weekofday = 7;}if(hour < 0){hour = 0;}//莫忘了计算点击的时间时 加上开始时间hour += HOURS[0];if(curClickView!=null){curClickView.setBackground(null);if(curClickView.getId() == v.getId()){curClickView = null;//跳转到添加课程界面return;}}curClickView = v;curClickView.setBackground(getResources().getDrawable(R.drawable.bg_course_add));curClickView.setAlpha((float)0.5);}});courseLayout.addView(tx);}}}}

4>左侧时间轴格子

<pre name="code" class="java">/** * 时间轴 * @param hour 几点 */public void addTimeView(int hour){RelativeLayout layout = new RelativeLayout(mContext);layout.setLayoutParams(mHourParams);//第一个格子里显示2个时间 24点 1点if(hour == 0){RelativeLayout.LayoutParams layoutParams= new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);TextView textView = new TextView(mContext);textView.setText("0"+HOURS[0]+":00");textView.setLayoutParams(layoutParams);textView.setTextAppearance(mContext, R.style.weekViewTimeText);layout.addView(textView);}//第一个时间显示在格子顶部 其它时间显示在底部hour = HOURS[hour+1];TextView textView = new TextView(mContext);textView.setLayoutParams(mHourTextParams);textView.setTextAppearance(mContext, R.style.weekViewTimeText);StringBuilder builder = new StringBuilder();builder.append(hour < 10?("0"+hour):hour);builder.append(":00");//22点不显示textView.setText(builder.toString());if(hour == 22){textView.setVisibility(View.INVISIBLE);}layout.addView(textView);//22点横线不显示if(hour != 22){TextView lineView = new TextView(mContext);lineView.setLayoutParams(mHourLineParams);lineView.setBackgroundColor(getResources().getColor(R.color.week_view_black));layout.addView(lineView);}timeLayout.addView(layout);}

思路二代码

自定义view显示课程位置

<pre name="code" class="java">/** * 根据课程时间绘制课程显示的位置 * @param name    课程名称 * @param sHour   课程开始时间 * @param sHour   课程开始分钟 * @param min     这节课有多少分钟 * @param weekday 周几 */public void addCourseView(Lesson bean){int[] sParams = DateUtil.getTime(bean.getsTime());int[] eParams = DateUtil.getTime(bean.geteTime());if(sParams == null || eParams == null){return;}//开始时间 分钟  总时间int sHour,sMin,eHour,eMin,min;sHour = sParams[0];sMin = sParams[1];eHour= eParams[0];eMin = eParams[1];if(eHour > sHour || eMin > sMin){min = (eHour - sHour)*60+(eMin - sMin);if(min < 40){min = 40;}//课程高度float minHeight = (float)gridHeight/(float)60;int cHeight = (int)(((float)gridHeight/(float)60)*min);int weekday = DateUtil.getWeekOfDate(bean.getLessonDate());if(weekday == 0){weekday = 7;}//1.添一个相对布局 来存储图片和文字RelativeLayout layout = new RelativeLayout(mContext);layout.setTag(String.valueOf(bean.getId()));RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(aveWidth,cHeight);//Calculate the location of the course Since the beginning of the course is from 7 points  rlp.topMargin = (sHour-7)*gridHeight+(int)(minHeight*sMin);rlp.leftMargin = firstGridWidth+(weekday-1)*aveWidth;layout.setLayoutParams(rlp);//设置背景框layout.setBackgroundResource(R.drawable.course_bg);//设置背景颜色GradientDrawable  drawable =(GradientDrawable) layout.getBackground();drawable.setColor(ColorUtils.getFillColor(1));//设置描边颜色drawable.setStroke(DensityUtils.dp2px(mContext, 2),ColorUtils.getStrokeColor(2));//bean.status == ClientCode.YS?mContext.getResources().getColor(background[0]):mContext.getResources().getColor(background[DateUtil.getWeekDay()])//设置不透明度layout.getBackground().setAlpha(222);//2.添加课程TextView courseInfo = new TextView(mContext);StringBuilder builder = new StringBuilder();builder.append(bean.getsTime());builder.append("\n");builder.append(" ");builder.append(bean.getName());courseInfo.setText(builder.toString());// 偏移由这节课是星期几决定//rlp.addRule(RelativeLayout.RIGHT_OF, 1);// 字体居中//courseInfo.setGravity(Gravity.CENTER);RelativeLayout.LayoutParams layoutParams= new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);courseInfo.setTextSize(12);courseInfo.setLayoutParams(layoutParams);courseInfo.setTextColor(Color.WHITE);layout.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) { //课程信息界面}});layout.addView(courseInfo);//课程以上显示已经图标if(bean.getStatus() == 1){layout.addView(addClassOkIcon());}mUserCourseLayout.addView(layout);}}
