我正在尝试显示联系信息,而对于stackOverflow上的其他问题,我有以下代码段

String[] projection = new String[] {
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
        ContactsContract.CommonDataKinds.Email.DISPLAY_NAME
     };

    Uri contacts =  ContactsContract.Contacts.CONTENT_LOOKUP_URI;
    //id of the Contact to return.
    long id = 3;

    //Make the query. 
    Cursor managedCursor = managedQuery(contacts,
                                        projection, // Which columns to return 
                                        null,       // Which rows to return (all rows)
                // Selection arguments (with a given ID)
                                        ContactsContract.Contacts._ID = "id", 
                // Put the results in ascending order by name
                                        ContactsContract.Contacts.DISPLAY_NAME + " ASC");

似乎2.2中的managedQuery已被更改(我相信原来的问题,我将其引用到2.0)

2.2中有什么变化?我找不到为联系人显示电子邮件,电话号码等的方法

编辑:这是我从android调试日志中找到的全部内容

答案 0 :(得分:1)

我不知道Contacts.CONTENT_LOOKUP_URI的作用,但我使用RawContacts.CONTENT_URI

因此,尝试Uri contacts = ContactsContract.RawContacts.CONTENT_URIUri contacts = ContactsContract.Contacts.CONTENT_URI也应该有用。

如果你没有指定selectionArgs(第三个参数),请保留selection(第四个参数),因为只有在给出selection时它们才会生成。 / p>
