我正在开发Android应用程序。我必须将事件添加到原生Android日历中。所以我尝试了以下代码:
if (Build.VERSION.SDK_INT >= 8 ) {
l_eventUri = Uri.parse("content://com.android.calendar/events");
} else {
l_eventUri = Uri.parse("content://calendar/events");
}
Cursor cursor = getContentResolver() .query(Uri.parse(getCalendarUriBase(this)),new String[] { "calendar_id", "displayname"}, null,null, null);
cursor.moveToFirst();
// fetching calendars name
String CNames[] = new String[cursor.getCount()];
// fetching calendars id
int[] CalIds = new int[cursor.getCount()];
for (int i = 0; i < CNames.length; i++) {
CalIds[i] = cursor.getInt(0);
CNames[i] = cursor.getString(1);
cursor.moveToNext();
}
// get calendar
Calendar cal = Calendar.getInstance();
Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
ContentResolver cr = getContentResolver();
// event insert
ContentValues values = new ContentValues();
values.put("calendar_id",111);
values.put("title", "Reminder Title");
values.put("allDay", 0);
values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
values.put("description", "Reminder description");
//Event Id
values.put("_id", 23);
//0~ default; 1~ confidential; 2~ private; 3~ public
values.put("visibility", 0);
//0~ false; 1~ true
values.put("hasAlarm", 1);
//status: 0~ tentative; 1~ confirmed; 2~ canceled
values.put("eventStatus", 1);
//0~ opaque, no timing conflict is allowed; 1~ transparency, allow overlap of scheduling
values.put("transparency", 0);
Uri event = cr.insert(EVENTS_URI, values);
// reminder insert
Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
values = new ContentValues();
values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
values.put( "method", 1 );
values.put( "minutes", 10 );
cr.insert( REMINDERS_URI, values );
private String getCalendarUriBase(Activity act) {
String calendarUriBase = null;
Uri calendars = Uri.parse("content://calendar/calendars");
Cursor managedCursor = null;
try {
managedCursor = act.managedQuery(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.managedQuery(calendars, null, null, null, null);
} catch (Exception e) {
}
if (managedCursor != null) {
calendarUriBase = "content://com.android.calendar/";
}
}
return calendarUriBase;
}
当我运行此代码时,我收到IllegalArgumentException
。
java.lang.IllegalArgumentException: Unknown URL content://com.android.calendar/
我认为错误是因为getCalendarUriBase()
方法。我搜索了很多其他方法,但到目前为止大多数开发人员都遵循上面的代码片段,因为这适用于每个Android版本。如何解决?
答案 0 :(得分:3)
当您尝试执行此行时,您错过了calendars
Cursor cursor = getContentResolver().query(
Uri.parse(getCalendarUriBase(this)), /* <-- unknown URL content */
new String[] { "calendar_id", "displayname" },
null,null,null);
产生IllegalArgumentException
。
只需在calendars
之后添加getCalendarUriBase(this)
。
Cursor cursor = getContentResolver().query(
Uri.parse(getCalendarUriBase(this)+"calendars"),
new String[] { "_id", "displayName" },
null,null,null);
注意:强>
- 如果从
_id
表格查询,请使用calendars
获取日历ID。calendar_id
被定义为其他表格中的外键(例如events
)。- 对GingerBread或以下版本使用
displayName
。对于冰淇淋三明治及以上,请使用calendar_displayName
。
添加活动时,您需要包括:日历ID,开始日期,结束日期(或重复规则)和事件时区。除了时区,你已经包括了所有时区。尝试添加
values.put("eventTimezone", TimeZone.getDefault().getID());
在插入活动之前。
