如何做到在android系统规划/业务日历 [英] How to do Planner/ business Calendar in android

问题描述

我打算做包含以下日期动态事件日历。但我没有得到这方面很好的样本。
什么是Android或分享一些想法确切的名字叫根据图像的下方。我得到了很多的apk和形象与它有关。
但它背后没有确切的想法，做Android的支持。我的计划是，以显示月，周，日历明智的。
在谷歌搜索后，很多我写这些。
难道它支持所有从2.3到4版本我已经看到上面verison 4一些博客业务日历支持上。
非常感谢善良和伟大的想法。

I got many apk and image related to it. but no exact idea behind it, does android support it. I plan is to show calendar in Month, week, day wise. After searching lot in google I am writing this. Does it supports all version from 2.3 to 4. i have seen some blog business calendar supports on above verison 4. Thanks a lot for kind and great ideas.

推荐答案

试着用 GridView控件来实现，低于code为的GridView适配器：

Try to implement with GridView, below code for Gridview Adapter :

public class GridCellAdapter extends BaseAdapter //implements OnClickListener 
 {
  private final Context _context;

  private final List list;
  private static final int DAY_OFFSET = 1;
  private final String[] months = { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct","Nov", "Dec" };
  private final int[] daysOfMonth = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };
  private int daysInMonth;
  private int currentDayOfMonth;
  private int currentWeekDay;
  Calendar calendar;
  private Button gridcell;

  List objects;

  // Days in Current Month
  public GridCellAdapter(Context context, int textViewResourceId, int month, int year, List objects) 
  {
   super();
   this._context = context;
   this.list = new ArrayList();
   this.objects=objects;
   Calendar calendar = Calendar.getInstance();
   setCurrentDayOfMonth(calendar.get(Calendar.DAY_OF_MONTH));
   setCurrentWeekDay(calendar.get(Calendar.DAY_OF_WEEK));

   // Print Month
   printMonth(month, year);
  }

  private String getMonthAsString(int i) 
  {
   return months[i];
  }

  private int getNumberOfDaysOfMonth(int i) 
  {
   return daysOfMonth[i];
  }

  public String getItem(int position) 
  {
   return list.get(position);
