如何将联系人添加到组android [英] how to add a contact to a group android

问题描述

我有以下代码将联系人添加到组中，并将其添加到android的联系人应用/人脉应用中，它确实添加了该组，但没有添加该组中的联系人，我想念的是什么？我成功添加了联系人，同时也创建了组，我确实获得了这两个东西的ID，我使用以下代码将联系人与该组相关联，但它不起作用，组始终为空。

I have following code to add contact to a group into android's contact app / people app, it does add the group but not the contact in that group, what am i missing ? I am adding contact successfully also creating group, i do get the ids of both the things , i m using following code to associate the contact with the group but its not working , group is always empty.

 public Uri addToGroup(long personId, long 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.getActivity().getContentResolver().insert(
            ContactsContract.Data.CONTENT_URI, values);

}

****更新*****
我发现的另一件事是，我创建的这个群组与Google不同步，这可能就是未添加联系人的原因。

****update ***** Another thing i found is this group which i created doesn't get sync with google , probably thats the reason contacts aren't getting added.

推荐答案

最后可以将联系人添加到组中，这是必需的，创建一个与Google帐户同步的联系人（强制性），然后创建一个可以同步到默认同步服务的组，然后按照以下方式添加联系人在上面的代码中添加。

Finally could add a contact to group, this is what was required, create a contact that syncs with google account (mandatory), second create a group that can sync to default sync service and then add contact the way i am adding in above code.

如果您想知道如何创建可以同步的群组，这里就是

if you are curious in knowing how to create group that can sync, here it is

public String createGroup(String name) {

    String[] GROUP_PROJECTION = new String[] { ContactsContract.Groups._ID,     ContactsContract.Groups.TITLE };

    try {
        ContentValues groupValues = null;
        ContentResolver cr = this.getContentResolver();
        groupValues = new ContentValues();
        groupValues.put(ContactsContract.Groups.TITLE, name);
        groupValues.put(ContactsContract.Groups.SHOULD_SYNC,true);
        cr.insert(ContactsContract.Groups.CONTENT_URI, groupValues);

    }
    catch(Exception e){
        Log.d("########### Exception :",""+e.getMessage());
        return "1";
    }

    String groupID = null;
    Cursor getGroupID_Cursor = null;
    getGroupID_Cursor = this.getContentResolver().query(ContactsContract.Groups.CONTENT_URI,  GROUP_PROJECTION, ContactsContract.Groups.TITLE+ "=?", new String[]{name}, null);

    getGroupID_Cursor.moveToFirst();
    groupID = (getGroupID_Cursor.getString(getGroupID_Cursor.getColumnIndex("_id")));

    return groupID;


}
