我想查询联系人内容提供商,以便联系人的IM类型等于“XYZ”。

我尝试了以下方式,但我没有得到任何结果:

    Uri uri1 = ContactsContract.Contacts.CONTENT_URI;
    String[] projection1 = null;
    String selection1 = null;
    String[] selectionArgs1 = null;
    String sortOrder1 = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC";
    Cursor cursor1 = context.getContentResolver().query(uri1, projection1, selection1, selectionArgs1, sortOrder1);
    if (cursor1 != null && cursor1.getCount() > 0) {
        while (cursor1.moveToNext()) {
            int contactId = Integer.parseInt(cursor1.getString(cursor1.getColumnIndex(ContactsContract.Contacts._ID)));

            Uri uri2 = ContactsContract.Data.CONTENT_URI;
            String[] projection2 = null;
            String selection2 = ContactsContract.CommonDataKinds.Im.PROTOCOL + " = ? AND " + ContactsContract.Contacts._ID + " = ? ";
            String[] selectionArgs2 = new String[]{"XYZ", contactId + ""};
            String sortOrder2 = null;
            Cursor cursor2 = context.getContentResolver().query(uri2, projection2, selection2, selectionArgs2, sortOrder2);
            if (cursor2 != null && cursor2.getCount() > 0) {
                while (cursor2.moveToNext()) {
                    Log.i(TAG, "Name: " + cursor2.getString(cursor2.getColumnIndex(ContactsContract.Data.DISPLAY_NAME)));

                }
                DatabaseUtils.dumpCursor(cursor2);
            }
        }
        cursor1.close();
    }

我没有使用上面的代码获取任何日志。

PS:我没有使用内置协议,如AIM,Windows Live,Yahoo或Skype。它是我的自定义协议,称之为“XYZ”。

为此,您需要查询ContactsContract.Data.CONTENT_URI并使用mime类型作为IM,然后标签或类型字段(不确定)保存您所说的“XYZ”和值中的IM类型您将获得类似用户名的值。

此表中有一个外键,它链接到raw_contacts表的原始联系人ID。

Cursor cursor = getActivity().getApplicationContext().getContentResolver().query(
                ContactsContract.Data.CONTENT_URI, null, ContactsContract.Data.MIMETYPE + "=?", new String[]{ContactsContract.CommonDataKinds.Im.CONTENT_ITEM_TYPE}, null);
        if(cursor!=null) {
            cursor.moveToFirst();
            do {
                String value = cursor
                        .getString(cursor
                                .getColumnIndex(ContactsContract.CommonDataKinds.Im.DATA));

                //Types are defined in CommonDataKinds.Im.*
                int imppType = cursor
                        .getInt(cursor
                                .getColumnIndex(ContactsContract.CommonDataKinds.Im.TYPE));

                //Protocols are defined in CommonDataKinds.Im.*
                int imppProtocol = cursor
                        .getInt(cursor
                                .getColumnIndex(ContactsContract.CommonDataKinds.Im.PROTOCOL));
                //and in this protocol you can check your custom value
            }while (cursor.moveToNext());
            cursor.close();
        }

我偶然发现了同样的问题。原来,该协议应该是Int而不是String。如果是自定义的,则应使用ContactsContract.CommonDataKinds.Im.PROTOCOL_CUSTOM,它是-1的别名。
