苹果和Android通讯录的生日,Android Applicaiton – 如何获得联系人的生日

一些人在网上看了之后找到了答案.必须要做的是：

>获取联系人列表

>对于每个联系人,请获取contactId

>使用contactid获取生日

以下是代码段：

ContentResolver cr = getContentResolver(); //getContnetResolver()

String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME };

Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, projection, null, null,

ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");

while (cur.moveToNext()) {

Map contactInfoMap = new HashMap();

String contactId = cur.getString(cur.getColumnIndex(ContactsContract.Data._ID));

String displayName = cur.getString(cur.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));

String columns[] = {

ContactsContract.CommonDataKinds.Event.START_DATE,

ContactsContract.CommonDataKinds.Event.TYPE,

ContactsContract.CommonDataKinds.Event.MIMETYPE,

};

String where = Event.TYPE + "=" + Event.TYPE_BIRTHDAY +

" and " + Event.MIMETYPE + " = '" + Event.CONTENT_ITEM_TYPE + "' and " + ContactsContract.Data.CONTACT_ID + " = " + contactId;

String[] selectionArgs = null;

String sortOrder = ContactsContract.Contacts.DISPLAY_NAME;

Cursor birthdayCur = cr.query(ContactsContract.Data.CONTENT_URI, columns, where, selectionArgs, sortOrder);

if (birthdayCur.getCount() > 0) {

while (birthdayCur.moveToNext()) {

String birthday = birthdayCur.getString(birthdayCur.getColumnIndex(ContactsContract.CommonDataKinds.Event.START_DATE));

}

}

birthdayCur.close();

}

cur.close();
