android contacts
本章和大家分享的是手机通讯录方面的经验，需求背景:对手机通讯录进行增、删、改、查，或者有时候App需要与手机 contacts进行交互或共享contacts。
我们都知道android系统没有完全将contacts向developer开放，开发人员只能通过android提供的有限的Api对contacts进行操作，我们只能通过ContentProvider对contacts的数据进行增、删、改、查等操作，并不能改变到其表结构。
首先，我们来看下如何通过ContentProvider查找contacts，以下我以查找其姓、名、公司、家庭电话、工作电话、移动电话、传真、邮箱、城市、省份、国家、出生年月为例：
1 /**
2 * 取得family_name和given_name
3 */
4 Cursor nameCur=cr.query(ContactsContract.Data.CONTENT_URI,
5 new String[] {Data.CONTACT_ID, StructuredName.DISPLAY_NAME, StructuredName.FAMILY_NAME, StructuredName.GIVEN_NAME, StructuredName.MIDDLE_NAME},
6 ContactsContract.Data.CONTACT_ID + "=?" + " AND "
7 + ContactsContract.Data.MIMETYPE + "='" + ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE + "'",
8 new String[]{android_id}, null);
9 if(nameCur.moveToFirst()){
10 firstName=nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
11 lastName=nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME));

98 addressCur.close();

100 // 根据contact_ID取得MobilePhone号码
101 Cursor birthdayCur = cr.query(ContactsContract.Data.CONTENT_URI,
102 new String[] {ContactsContract.CommonDataKinds.Event.DATA},
103 ContactsContract.Data.CONTACT_ID + "=?" + " AND "

106 new String[]{android_id,ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY)}, null);
107 if(birthdayCur.moveToFirst()){
108 birthday=birthdayCur.getString(birthdayCur.getColumnIndex(ContactsContract.CommonDataKinds.Event.DATA));
109 }
110 birthdayCur.close();
以上只是查找了contacts的部分字段，同鞋们可以自行拓展，比如说查找其IM,Organization,Nickname,WebSite等等.
得到contacts联系人之后，我们可以对其做相应的修改，修改完成后，我们要将数据更新到android contacts数据库中，以下就是更新的范例:
1 ArrayList ops =
2 new ArrayList();
3 // 更新family_name和given_name
4 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
5 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
6 + ContactsContract.Data.MIMETYPE + "=?",
7 new String[]{android_id,ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE})
8 .withValue(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME, firstN)
9 .withValue(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, lastN)
10 .build());
11 // 更新comany
12 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
13 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
14 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
15 + ContactsContract.CommonDataKinds.Organization.TYPE + "=?",
16 new String[]{android_id,ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Organization.TYPE_WORK)})
17 .withValue(ContactsContract.CommonDataKinds.Organization.COMPANY, com)
18 .build());
19 // 更新homePhone
20 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
21 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
22 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
23 + ContactsContract.CommonDataKinds.Organization.TYPE + "=?",
24 new String[]{android_id,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_HOME)})
25 .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, hp)
26 .build());
27 // 更新workPhone
28 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
29 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
30 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
31 + ContactsContract.CommonDataKinds.Organization.TYPE + "=?",
32 new String[]{android_id,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_WORK)})
33 .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER,wp)
34 .build());
35 // 更新mobilePhone
36 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
37 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
38 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
39 + ContactsContract.CommonDataKinds.Organization.TYPE + "=?",
40 new String[]{android_id,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)})
41 .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER,mp)
42 .build());
43 // 更新faxPhone
44 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
45 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
46 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
47 + ContactsContract.CommonDataKinds.Organization.TYPE + "=?",
48 new String[]{android_id,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_FAX_HOME)})
49 .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER,fp)
50 .build());
51 // 更新email
52 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
53 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
54 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
55 + ContactsContract.CommonDataKinds.Email.TYPE + "=?",
56 new String[]{android_id,ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Email.TYPE_WORK)})
57 .withValue(ContactsContract.CommonDataKinds.Email.DATA,em)
58 .build());
59 // 更新city,state,country
60 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
61 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
62 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
63 + ContactsContract.CommonDataKinds.StructuredPostal.TYPE + "=?",
64 new String[]{android_id,ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.StructuredPostal.TYPE_HOME)})
65 .withValue(ContactsContract.CommonDataKinds.StructuredPostal.CITY, city)
66 .withValue(ContactsContract.CommonDataKinds.StructuredPostal.REGION, state)
67 .withValue(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY,cou)
68 .build());
69 // 更新birthday
70 ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
71 .withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND "
72 + ContactsContract.Data.MIMETYPE + "=?"+ " AND "
73 + ContactsContract.CommonDataKinds.Event.TYPE + "=?",
74 new String[]{android_id,ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY)})
75 .withValue(ContactsContract.CommonDataKinds.Event.DATA, bir)
76 .build());
77 try
78 {
79 ContentProviderResult[] res = context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
80 // Log.i("contact", "android_id="+android_id+",firstName="+firstName+",lastName="+lastName);
81 // appState.db.insertContactToTag(tagId,String.valueOf(contactId));
82 }
83 catch (RemoteException e)
84 {
85 // error
86 }catch (OperationApplicationException e)
87 {
88 // error
89 }
同样以上更新也仅是对contact的部分字段进行了更新，我相信聪明的你，仔细阅读，细细推敲一番，定能找到其中的规律，从而对犹如IM,Nickname,Event,Organization等字段进行更新。
以上只是对已经存在的contacts进行操作，那么我们一开始该如何向里面插入一条数据呢，以下代码是实现向数据库中插入一条数据的操作。
1 ArrayList ops = new ArrayList();
2 int rawContactInsertIndex = ops.size();
3
4 ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
5 .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, null)
6 .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null)
7 .build());
8
9 //------------------------------------------------------ Names
10 if(firstN != null && lastN!=null )
11 {
12 ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
13 .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, rawContactInsertIndex)
14 .withValue(ContactsContract.Data.MIMETYPE,
15 ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)
16 .withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, firstN+lastN)
17 .withValue(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME, firstN)
18 .withValue(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, lastN)
19 .build());
20 }
21
22 //------------------------------------------------------ Organization
23 if(com!=null)
24 {

45 }
46 //------------------------------------------------------ Work Numbers
47 if(wp != null)

53 .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, wp)
54 .withValue(ContactsContract.CommonDataKinds.Phone.TYPE,
55 ContactsContract.CommonDataKinds.Phone.TYPE_WORK)
56 .build());
57 }
58 //------------------------------------------------------ Mobile Number
59 if(mp != null)
60 {
61 ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)

69 }
70 //------------------------------------------------------ Fax Number
71 if(fp != null)
72 {

75 .withValue(ContactsContract.Data.MIMETYPE,

78 .withValue(ContactsContract.CommonDataKinds.Phone.TYPE,
79 ContactsContract.CommonDataKinds.Phone.TYPE_FAX_HOME)
80 .build());
81 }
82
83 //------------------------------------------------------ Email
84 if(em != null)
85 {

87 .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, rawContactInsertIndex)
88 .withValue(ContactsContract.Data.MIMETYPE,

90 .withValue(ContactsContract.CommonDataKinds.Email.DATA, em)
91 .withValue(ContactsContract.CommonDataKinds.Email.TYPE, ContactsContract.CommonDataKinds.Email.TYPE_WORK)
92 .build());
93 }

104 .withValue(ContactsContract.CommonDataKinds.StructuredPostal.TYPE,
105 ContactsContract.CommonDataKinds.StructuredPostal.TYPE_HOME)
106 .build());
107 }
108
109 //------------------------------------------------------ Birthday
110 if(bir != null)
111 {
112 ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
113 .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, rawContactInsertIndex)
114 .withValue(ContactsContract.Data.MIMETYPE,
115 ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE)
116 .withValue(ContactsContract.CommonDataKinds.Event.DATA, bir)
117 .withValue(ContactsContract.CommonDataKinds.Event.TYPE,
118 ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY)
119 .build());
120 }
121 try
122 {
123 ContentProviderResult[] res = context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
124
125 return res;
126 }
127 catch (RemoteException e)
128 {
129 // error
130 }catch (OperationApplicationException e)
131 {
132 // error
133 }
实现以上代码便可将一条数据插入到contacts数据库中，同样，你也可以插入其他的字段，而且你也可以细细研究下ContentProviderResult[]，看看进行这些操作后，其返回的结果都是什么。
以上实现了对android contacts 增、删、改、查中的三种，下面的代码就是实现删的，删除一个contacts相对来说比较简单些。
1 String where = ContactsContract.Data._ID + " = ? ";
2 String[] params = new String[] {android_id};
3
4 ArrayList ops = new ArrayList();
5 ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI)
6 .withSelection(where, params)
7 .build());
8 try {
9 cr.applyBatch(ContactsContract.AUTHORITY, ops);
10 } catch (RemoteException e) {
11 // TODO Auto-generated catch block
12 e.printStackTrace();
13 } catch (OperationApplicationException e) {
14 // TODO Auto-generated catch block
15 e.printStackTrace();
16 }
删除一个contacts有很多的选择，你可以只删除电话这一块，也可以删除联系人信息这一块，而且你不仅可以将id做作为条件进行删除，你也可以将联系电话做为条件进行删除，你也还可以以用户名做为条件进行删除。
以上代码便可以实现对android contacts的增、删、改、查等操作。最后不要忘了赋予APP 对contacts读写的权限：
