如何在android中執行計劃器/業務日曆

Question

我打算在日期下面做包含動態事件的日曆。但我沒有得到有關它的好樣品。 什麼是Android中的下圖所示的確切名稱調用或共享一些想法。我有很多apk和與它相關的圖像。 但它背後沒有確切的想法，android是否支持它。我打算在月，周，日明智地展示日曆。 在谷歌搜索很多我寫這個。 它是否支持從2.3到4的所有版本。我已經在上述版本4上看到了一些博客業務日曆支持。 非常感謝您的好意和好點子。

嘗試與GridView實現，下面的代碼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); 
    } 

    @Override 
    public int getCount() 
    { 
    return list.size(); 
    } 

    /**

    { 
    int trailingSpaces = 0; 
    int daysInPrevMonth = 0;

    getMonthAsString(currentMonth);

    GregorianCalendar cal = new GregorianCalendar(yy, currentMonth, 1); 
    if (currentMonth == 11) 
    { 
    prevMonth = currentMonth - 1; 
    daysInPrevMonth = getNumberOfDaysOfMonth(prevMonth); 
    nextMonth = 0; 
    prevYear = yy; 
    nextYear = yy + 1; 
    } 
    else if (currentMonth == 0) 
    { 
    prevMonth = 11; 
    prevYear = yy - 1; 
    nextYear = yy; 
    daysInPrevMonth = getNumberOfDaysOfMonth(prevMonth); 
    nextMonth = 1;

    else

    { 
    ++daysInMonth; 
    } 
    else if (mm == 3) 
    { 
    ++daysInPrevMonth; 
    } 
    } 

    for (int i = 0; i < trailingSpaces; i++) 
    { 
    list.add(String.valueOf((daysInPrevMonth - trailingSpaces + DAY_OFFSET) + i) + "-GREY" + "-" + getMonthAsString(prevMonth)+ "-" + prevYear+"-no");

screen_gridcell.xml代碼：
