问题
I read about ContactsContract.CommonDataKinds.GroupMembership, but I can't figure out what URI use to insert to.
I have prepared this method:
public static Uri addToGroup(ContentResolver resolver, long personId,
long groupId) {
ContentValues values = new ContentValues();
values.put(ContactsContract.CommonDataKinds.GroupMembership.CONTACT_ID, personId);
values.put(ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID, groupId);
return resolver.insert(uri, values);//URI is not known
}
Can someone tell me what URI to use in SDK 2.0+?
回答1:
I found the resolution and I post it here:
public Uri addToGroup(long personId, long groupId) {
//remove if exists
this.removeFromGroup(personId, groupId);
ContentValues values = new ContentValues();
values.put(ContactsContract.CommonDataKinds.GroupMembership.RAW_CONTACT_ID,
personId);
values.put(
ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID,
groupId);
values
.put(
ContactsContract.CommonDataKinds.GroupMembership.MIMETYPE,
ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE);
return this.ctx.getContentResolver().insert(
ContactsContract.Data.CONTENT_URI, values);
}
But I don't get something, why do I have to use RAW_CONTACT_ID
and not CONTACT_ID
, the later raises nullpointerexception.
