如何更新现有联系人？答案

【发布时间】：2012-01-19 09:07:15
【问题描述】：

我有一个现有联系人，我需要为该现有联系人添加工作地址。我正在使用以下代码，但它不起作用。

String selectPhone = Data.CONTACT_ID + "=? AND " + Data.MIMETYPE + "='" + 
    ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE + 
    "'" + " AND " + ContactsContract.CommonDataKinds.StructuredPostal.TYPE + "=?"; 
String[] phoneArgs = new String[]
    {String.valueOf(ContactId), String.valueOf(
    ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)}; 
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI) 
    .withSelection(selectPhone, phoneArgs) 
    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.STREET, STREET)
    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.CITY, CITY) 
    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.REGION, REGION)
    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE, POSTCODE) 
    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY, COUNTRY)  
    .build()); 
this.context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

有什么解决办法吗？

如果只有 1 个电话号码或姓名或电子邮件，则此答案是正确的。如果有多个电话号码。例如你应该添加String where = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.CommonDataKinds.Phone.NUMBER + " = ?"; String[] numberParams = new String[]{ContactId, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, oldPhoneNumber};来正确修改一个contact_id中的所有电话号码

【解决方案2】：

//对不起我的英语不好 // 好像在第一篇文章中您忘记在操作中添加MimeType。

String selectPhone = Data.RAW_CONTACT_ID + "=? AND " + Data.MIMETYPE + "='" + 
                    ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE +  "'" ; 
                String[] phoneArgs = new String[]{String.valueOf(rawContactId)}; 
                ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI) 
                    .withSelection(selectPhone, phoneArgs) 
                    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.TYPE, ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)
                    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.STREET, STREET)
                    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.CITY, CITY) 
                    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.REGION, REGION)
                    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE, POSTCODE) 
                    .withValue(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY, POSTCODE)

**

//只要添加这一行.withValue(Data.MIMETYPE, "vnd.android.cursor.item/postal-address_v2")

**

     .build());
this.context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

请检查并告诉我结果

我终于找到了合适的解决方案。非常感谢How to modify existing Contact

秘诀在于您必须为 .withSelection 传递两个值，如下所示：

.withSelection(Data.RAW_CONTACT_ID + " = ?", new String[] {String.valueOf(id)})
.withSelection(Data._ID + " = ?", new String[] {mDataId})

其中通过Data._ID的值mDataId是这样获得的：

Cursor mDataCursor = this.context.getContentResolver().query(
                        Data.CONTENT_URI,
                        null,
                        Data.RAW_CONTACT_ID + " = ? AND " + Data.MIMETYPE + " = ?",
                        new String[] { String.valueOf(id), ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE},
                        null);

                if(mDataCursor.getCount() > 0) {
                    mDataCursor.moveToFirst();
                    mDataId = getCursorString(mDataCursor, Data._ID);
                    MLog.v("Data", "Found data item with MIMETYPE");                            
                    mDataCursor.close();

                } else {
                    MLog.v("Data", "Data doesn't contain MIMETYPE");
                    result = ERROR;
                    mDataCursor.close();
                }

getCursorString 方法类似于：

private static String getCursorString(Cursor cursor, String columnName) {
        int index = cursor.getColumnIndex(columnName);
        if(index != -1) return cursor.getString(index);
        return null;
    }

只有这个才是诀窍..

【解决方案4】：

每个字段（电子邮件、姓名、地址）都有自己的 mime 类型，您应该使用它来更新字段。

我们将使用 Data 表，其中每个 Data.RAW_CONTACT_ID 代表有关某些联系人的详细信息。

所以，我们需要找到 Data.RAW_CONTACT_ID，其中 id 是您要编辑的联系人的 id。

希望这段代码对你有所帮助。

    String selectPhone = Data.RAW_CONTACT_ID + "=? AND " + Data.MIMETYPE + "='" + 
                        ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE +  "'" ; 
                    String[] phoneArgs = new String[]{String.valueOf(rawContactId)}; 
                    ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI) 
                        .withSelection(selectPhone, phoneArgs) 
                        .withValue(ContactsContract.CommonDataKinds.StructuredPostal.TYPE, ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)
                        .withValue(ContactsContract.CommonDataKinds.StructuredPostal.STREET, STREET)
                        .withValue(ContactsContract.CommonDataKinds.StructuredPostal.CITY, CITY) 
                        .withValue(ContactsContract.CommonDataKinds.StructuredPostal.REGION, REGION)
                        .withValue(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE, POSTCODE) 
                        .withValue(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY, POSTCODE)  
                        .build());
this.context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

如果已创建新联系人，但没有地址，现在您想向该联系人添加地址。在这种情况下，使用与上面相同的查询，但只需将 newUpdate 更改为 newInsert，因为这样的行还不存在。

【解决方案5】：

您应该在选择子句中使用“Data.RAW_CONTACT_ID”而不是“Data.CONTACT_ID”。

【解决方案6】：

也许您可以使用Intent and its ACTION_EDIT 让您的用户编辑工作地址...

这个不太理想，我之前试过但是不符合我的应用要求。
