android – 读写日历

我的目标是阅读和编写日历.

我能够从内容中读取数据：// calendar / calendars和content：// calendar / events

String uriString = "content://calendar/calendars";
  Log.i("INFO", "Reading content from " + uriString);
  readContent(uriString);
  uriString = "content://calendar/events";
  Log.i("INFO", "Reading content from " + uriString);
  readContent(uriString);

private void readContent(String uriString) {

  Uri uri = Uri.parse(uriString);
  Cursor cursor = mContext.getContentResolver().query(uri, null, null,
    null, null);
  if (cursor != null && cursor.getCount() > 0) {
   cursor.moveToFirst();
   String columnNames[] = cursor.getColumnNames();
   String value = "";
   String colNamesString = "";
   do {
    value = "";

    for (String colName : columnNames) {
     value += colName + " = ";
     value += cursor.getString(cursor.getColumnIndex(colName))
       + " ||";
    }

    Log.e("INFO : ", value);
   } while (cursor.moveToNext());

  }

 }

我也在日历中插入新记录,如：

String calUriString = "content://calendar/calendars";
   ContentValues values = new ContentValues();
   values.put("name", "Code Generate Calendar");
   values.put("displayName", "Code Generate Calendar");
   values.put("hidden", 0);
   values.put("color", "-7581685");
   values.put("access_level", "700");
   values.put("selected", "1");
   values.put("timezone", "Asia/Karachi");

   Uri calendarUri = context.getContentResolver().insert(
   Uri.parse(calUriString), values);

但它没有出现在日历中.

当我要在日历中插入新事件时：

ContentValues values = new ContentValues();
   values.put("calendar_id", 4);
   values.put("dtend", "1277337600000");
   values.put("dtstart", "1277251200000");
   // values.put("title", "first TEst event");
   values.put("transparency", 1);
   values.put("selected", 1);
   values.put("color", "-16380578");
   // values.put("lastDate", "6/25/2010");
   //values.put("access_level", 700);
   values.put("eventStatus", 1);
   values.put("eventTimezone", "UTC");
   values.put("timezone", "Asia/Karachi");
   values.put("allDay", 1);
   String eventUriString = "content://calendar/events";
   Uri eventUri = context.getContentResolver().insert(
   Uri.parse(eventUriString), values);

抛出该列无效的异常.

怎么可能.
谢谢

日历内容提供商不是Android SDK的一部分.它之前的Android版本之间已经发生了变化,并将再次发布.它可能无法在某些已使用自己的应用程序替换默认日历应用程序的设备上运行.

Do not use undocumented content providers.

解决方案与the question you asked 32 minutes previously相同 – 使用Google Calendar GData API来操纵用户的日历.
