Ich möchte die Daten von zuletzt hinzugefügt Ereignis von Android Kalender abrufen. Ich verwende diesen Code, um die letzte ID zu erhalten.Daten des letzten hinzugefügten Ereignisses aus Android-Kalender abrufen
public static long getNewEventId(ContentResolver cr, Uri cal_uri)
{
Uri local_uri = cal_uri;
if (cal_uri == null)
{
local_uri = Uri.parse("content://com.android.calendar/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;
}
Und dann füge ich einfach ein Ereignis mit diesem Code:
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", SelectedDate);
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FsREQ=DAILY");
intent.putExtra("endTime", SelectedDate + 60 * 60 * 1000);
intent.putExtra("title", "Advance Scheduler Event");
startActivity(intent);
Danach ich abrufen einfach die Daten dieses Ereignisses mit diesem Code:
public CalendarData EventDetails(int ID)
{
CalendarData temp = null;
// -------------------------------------------------------------------------------
ContentResolver cr = getContentResolver();
Cursor cursor_calendar;
if (Integer.parseInt(Build.VERSION.SDK) >= 8)
{
cursor_calendar = cr.query(
Uri.parse("content://com.android.calendar/calendars"),
new String[] { "_id", "displayname" }, null, null, null);
}
else
{
cursor_calendar = cr.query(
Uri.parse("content://calendar/calendars"), new String[] {
"_id", "displayname" }, null, null, null);
}
cursor_calendar.moveToFirst();
String[] CalNamess = new String[cursor_calendar.getCount()];
int[] CalIdss = new int[cursor_calendar.getCount()];
for (int i = 0; i < CalNamess.length; i++)
{
CalIdss[i] = cursor_calendar.getInt(0);
CalNamess[i] = cursor_calendar.getString(1);
cursor_calendar.moveToNext();
}
cursor_calendar.close();
// -------------------------------------------------------------------------------
Cursor cursor_event;
if (Integer.parseInt(Build.VERSION.SDK) >= 8)
{
cursor_event = cr.query(
Uri.parse("content://com.android.calendar/events"),
new String[] { "calendar_id", "title", "description",
"dtstart", "dtend", "eventLocation" }, null, null,
null);
}
else
{
cursor_event = cr.query(Uri.parse("content://calendar/events"),
new String[] { "calendar_id", "title", "description",
"dtstart", "dtend", "eventLocation" }, null, null,
null);
}
boolean flag = false;
String add = null;
cursor_event.moveToFirst();
String[] CalNames = new String[cursor_event.getCount()];
int[] CalIds = new int[cursor_event.getCount()];
for (int i = 0; i < CalNames.length; i++)
{
CalIds[i] = cursor_event.getInt(0);
if (ID == CalIds[i])
{
flag = true;
Toast.makeText(getApplicationContext(),
"ID Found : " + CalIds[i], Toast.LENGTH_LONG).show();
CalNames[i] = "Event"
+ cursor_event.getInt(0)
+ ": \nTitle: "
+ cursor_event.getString(1)
+ "\nDescription: "
+ cursor_event.getString(2)
+ "\nStart Date: "
+ cursor_event.getLong(cursor_event
.getColumnIndex("dtstart"))
+ cursor_event.getLong(cursor_event
.getColumnIndex("dtend"))
+ cursor_event.getString(5);
temp = new CalendarData();
temp.Title = cursor_event.getString(1);
temp.Description = cursor_event.getString(2);
// temp.StartDate = new Date(cursor_event.getLong(3));
// temp.EndDate = new Date(cursor_event.getLong(4));
temp.StartDate = cursor_event.getLong(cursor_event
.getColumnIndex("dtstart"));
temp.EndDate = cursor_event.getLong(cursor_event
.getColumnIndex("dtend"));
temp.Location = cursor_event.getString(5);
break;
}
cursor_event.moveToNext();
}
return temp;
}
Aber ich kann‘ t erhalten die Daten dieses Ereignisses. Ich verstehe nicht, wo das Problem liegt. Bitte, hilf mir, das zu lösen.
vielen Dank :) –
