Android日历,获取事件ID
我正在编写一个需要向Android日历中添加一些事件的应用程序。对于插入,我只使用了以下代码:
public void onItemClick(AdapterView<?> adapter, View curview, int position, long id) { WhoisEntry entry = this.adapter.getItem(position);
String domainName = entry.getDomainName();
Date expDate = entry.expirationDate;
Toast.makeText(getApplicationContext(), "Domain: " + domainName, Toast.LENGTH_SHORT).show();
Calendar cal = Calendar.getInstance();
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", entry.expirationDate);
intent.putExtra("allDay", false);
intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
intent.putExtra("title", "Expiration of " + entry.domainName);
startActivity(intent);
}
现在,我想知道是否有可能获得与该事件关联的ID,以这种方式在插入事件并将其ID保存到我的应用程序后,用户可以直接从应用程序内部调用该事件。可能吗?
回答:
我提取了用于将事件存储到android日历中的列的列表。这里的清单:
[0]“ originalEvent”(id = 830007842672)
[1]“ availabilityStatus”(id = 830007842752)
[2]“ ownerAccount”(id = 830007842840)
[3]“ _sync_account_type”(id = 830007842920)
[4]“可见性” (id = 830007843008)
[5]“ rrule”(id = 830007843080)
[6]“ lastDate”(id = 830007843144)
[7]“ hasAlarm”(id = 830007843216)
[8]“ guestsCanModify”(id = 830007843288)[ 9]“ guestsCanSeeGuests”(id =
830007843376)
[10]“执行”(id = 830007843464)
[11]“ rdate”(id = 830007843528)
[12]“透明度”(id = 830007843592)
[13]“时区”( id = 830007843672)
[14]“已选择”(id = 830007843744)
[15]“ dtstart”(id = 830007843816)[16]“标题”(id = 830007843888)
[17]“ _sync_time”(id = 830007843952)
[18]“ _id”(id = 830007844024)[19]“ hasAttendeeData”(id = 830007844088)[20]“
_sync_id”(id = 830007844176)
[21]“ commentsUri” (id = 830007844248)[22]“说明”(id = 830007844328)[23]“
htmlUri”(id = 830007844408)[24]“ _sync_account”(id = 830007844480)
[25]“ _sync_version”(id = 830007844560)
[ 26]“ hasExtendedProperties”(id = 830007844640)
[27]“ calendar_id”(id = 830007844736)
然后,如果我想获取事件的新事件ID:
public static long getNewEventId(ContentResolver cr, Uri cal_uri){ Uri local_uri = cal_uri;
if(cal_uri == null){
local_uri = Uri.parse(calendar_uri+"events");
}
Cursor cursor = cr.query(local_uri, new String [] {"MAX(_id) as max_id"}, null, null, "_id");
cursor.moveToFirst();
long max_val = cursor.getLong(cursor.getColumnIndex("max_id"));
return max_val+1;
}
和插入事件:
public void insertDomainEntry(Date exp_date, String name, long event_id){ SQLiteDatabase db = getWritableDatabase();
ContentValues values = new ContentValues();
values.put("exp_date", exp_date.getTime()/1000);
values.put("event_id", event_id);
values.put("domainname", name);
db.insertOrThrow("domains_events", null, values);
}
该解决方案似乎可行,即使这可能不是一个很好的解决方案。
的目的是为事件表创建一个新的事件条目,此处是使用此方法的代码:
@Override public void onItemClick(AdapterView<?> adapter, View curview, int position,
long id) {
WhoisEntry entry = this.adapter.getItem(position);
long event_id = CalendarUtils.getNewEventId(getContentResolver(), null);
Toast.makeText(getApplicationContext(), "Domain: " + entry.getDomainName(),
Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", entry.getExpiration().getTime());
intent.putExtra("_id", event_id);
intent.putExtra("allDay", false);
intent.putExtra("endTime", entry.getExpiration().getTime()+60*30);
intent.putExtra("title", "Expiration of " + entry.getDomainName());
startActivity(intent);
database.insertDomainEntry(entry.getExpiration(),
entry.getDomainName(), event_id);
}
根据评论中的要求,我添加了如何获取Calendar URI(基本上是日历的存储位置,应用程序尝试猜测它,在所有已知的可能的日历路径中进行搜索)
public static String getCalendarUriBase(Activity act) { String calendarUriBase = null;
Uri calendars = Uri.parse("content://calendar/calendars");
Cursor managedCursor = null;
try {
managedCursor = act.getContentResolver().query(calendars,
null, null, null, null);
} catch (Exception e) {
}
if (managedCursor != null) {
calendarUriBase = "content://calendar/";
} else {
calendars = Uri.parse("content://com.android.calendar/calendars");
try {
managedCursor = act.getContentResolver().query(calendars,
null, null, null, null);
} catch (Exception e) {
}
if (managedCursor != null) {
calendarUriBase = "content://com.android.calendar/";
}
}
calendar_uri= calendarUriBase;
return calendarUriBase;
}
