使用字符串值設置日曆訂單日期

Question

我被困了2天，最後放棄。我需要你的日曆功能幫助。該人員選擇一個產品（在按鈕上），並設置一條消息，並允許他們在可以重新訂購時添加提醒。現在我打開日曆，但無法讓日曆根據該產品設置日期。我不確定如何設置字符串值，調用它，並設置日曆日期。我知道這是基本的東西，但我很感激幫助！對不起，冗長的代碼。我想確保我包含了所有相關的東西。

這裏是我的代碼：

Button reorder1 = (Button) findViewById(R.id.rotramadol); 
Button reorder2 = (Button) findViewById(R.id.roaciphex); 
Button reorder3 = (Button) findViewById(R.id.roflexeril); 
reorder1.setOnClickListener(this); 
reorder2.setOnClickListener(this); 
reorder3.setOnClickListener(this); 

@Override 
public void onClick(View v) { 
    if (v.getId() == R.id.rotramadol) { 
//this one needs the calendar set 10 days from now 
     AlertDialog ad = new AlertDialog.Builder(this) 
       .setMessage(
         "Order Quantity 90 tabs requires 10 days") 
       .setTitle("Tramadol") 
       .setPositiveButton("Set Reminder", this) 
       .setNegativeButton("OK", this).setCancelable(false) 
       .create(); 
     ad.show(); 
    } else if (v.getId() == R.id.roaciphex) { 
//this one needs the calendar set 25 days from now 
     AlertDialog ad1 = new AlertDialog.Builder(this) 
       .setMessage("Order Quantity 30 tabs requires 25 days") 
       .setTitle("Aciphex") 
       .setPositiveButton("Set Reminder", this) 
       .setNegativeButton("OK", this).setCancelable(false) 
       .create(); 
     ad1.show(); 
    } else if (v.getId() == R.id.roflexeril) { 
//this one needs the calendar set 7 days from now 
     AlertDialog ad2 = new AlertDialog.Builder(this) 
       .setMessage("Order Quantity 30 tabs requires 7 days") 
       .setTitle("Flexeril") 
       .setPositiveButton("Set Reminder", this) 
       .setNegativeButton("OK", this).setCancelable(false) 
       .create(); 
     ad2.show(); 


@Override 
public void onClick(DialogInterface dialog, int which) { 
    // TODO Auto-generated method stub 

    switch (which) { 
    case DialogInterface.BUTTON_POSITIVE: // yes 

     Intent intent = new Intent(Intent.ACTION_INSERT); 
     intent.setType("vnd.android.cursor.item/event"); 
     intent.putExtra(Events.TITLE, "Reorder"); 
     intent.putExtra(Events.EVENT_LOCATION, ""); 
     intent.putExtra(Events.DESCRIPTION, 
       "https://www.place they reorder.com"); 

     GregorianCalendar calDate = new GregorianCalendar(); 
     intent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, 
       calDate.getTimeInMillis()); 
     intent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, 
       calDate.getTimeInMillis()); 

     intent.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, true); 

     intent.putExtra(Events.RRULE, "FREQ=DAILY;COUNT=1;"); 

     intent.putExtra(Events.ACCESS_LEVEL, Events.ACCESS_PRIVATE); 
     intent.putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY); 

     startActivity(intent); 

     break; 

    case DialogInterface.BUTTON_NEGATIVE: // no 

     dialog.cancel(); 

     break; 
    default: 
     break; 

    } 

}

我假設你正在試圖建立基於用戶選擇的日曆事件，嘗試下面的代碼

    Calendar calendar = Calendar.getInstance(); 
        calendar.add(Calendar.DATE, 5/*how many days from today*/); 
        Intent intent = new Intent(Intent.ACTION_EDIT); 
        intent.setType("vnd.android.cursor.item/event"); 
        intent.putExtra(Events.TITLE, "your title"); 
        intent.putExtra("beginTime", calendar.getTime()); 
        intent.putExtra("endTime", calendar.getTime() + DateUtils.MINUTE_IN_MILLIS * 30); 
        intent.putExtra(Events.EVENT_TIMEZONE, calendar.getTimeZone()); 
        startActivity(intent);
