在上一章 Android中联系人和通话记录详解（2）中分析了联系人相关的表和字段，在这一章中将分析联系人相关的基本数据操作(Insert,Query,Update,Delete)。

   1.添加(Insert)

     从contacts,data,mimetypes,raw_contacts表的关系可以看出，表raw_contacts为表data的父表，所以插入数据时，应该先在raw_contacts表中插入数据，再在data表中插入数据。

[java]  view plain  copy ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>();           ContentProviderOperation op1 = ContentProviderOperation                   .newInsert(ContactsContract.RawContacts.CONTENT_URI)                   .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null)                   .build();// 得到了一个添加内容的对象           operations.add(op1);              ContentProviderOperation op2 = ContentProviderOperation                   .newInsert(ContactsContract.Data.CONTENT_URI)                   .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)                   .withValue(                           ContactsContract.Data.MIMETYPE,                           ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)                   .withValue(ContactsContract.Data.DATA1, "小明").build();// 得到了一个添加内容的对象           operations.add(op2);              ContentProviderOperation op3 = ContentProviderOperation                   .newInsert(ContactsContract.Data.CONTENT_URI)                   .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)                   .withValue(                           ContactsContract.Data.MIMETYPE,                           ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)                   .withValue(ContactsContract.Data.DATA1, "1233232542")                   .withValue(ContactsContract.Data.DATA2, "2")// data2=2即type=2，表示移动电话                   .build();// 得到了一个添加内容的对象           operations.add(op3);              ContentProviderOperation op4 = ContentProviderOperation                   .newInsert(ContactsContract.Data.CONTENT_URI)                   .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)                   .withValue(                           ContactsContract.Data.MIMETYPE,                           ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)                   .withValue(ContactsContract.Data.DATA1, "test@email.com")                   .withValue(ContactsContract.Data.DATA2, "2")// data2=2即type=2，表示工作邮箱                   .build();// 得到了一个添加内容的对象           operations.add(op4);              getContext().getContentResolver().applyBatch("com.android.contacts",                   operations);// 执行批量操作   ContentProviderOperation类是为了使批量更新、插入、删除数据更加方便而引入的，在官方文档中指出推荐使用ContentProviderOperation类的原因有：1.所有的操作都在一个事务中执行，这样可以保证数据完整性；2.由于批量操作在一个事务中执行，只需要打开和关闭一个事务，比多次打开关闭多个事务性能要好些；3.使用批量操作和多次单个操作相比，减少了应用和content provider之间的上下文切换，这样也会提升应用的性能，并且减少占用CPU的时间，当然也会减少电量的消耗。

     2.查询（Query）     

[java]  view plain  copy public void queryContacts(Context context) {           ContentResolver cr = context.getContentResolver();           Cursor contactCursor = cr.query(ContactsContract.Contacts.CONTENT_URI,                   new String[] { ContactsContract.Contacts._ID }, null, null,                   ContactsContract.Contacts.SORT_KEY_PRIMARY);//在raw_contacts表中得到contactId           if (contactCursor != null && contactCursor.getCount() > 0)               while (contactCursor.moveToNext()) {                   long contactId = contactCursor.getLong(contactCursor                           .getColumnIndex(ContactsContract.Contacts._ID));                   Cursor dataCursor = cr.query(ContactsContract.Data.CONTENT_URI,                           new String[] { ContactsContract.Data.MIMETYPE,                                   ContactsContract.Data.DATA1,                                   ContactsContract.Data.DATA2,                                   ContactsContract.Data.DATA15 },                           ContactsContract.Data.RAW_CONTACT_ID + "=" + contactId,                           null, null);                   if (dataCursor != null && dataCursor.getCount() > 0) {                       while (dataCursor.moveToNext()) {                           String mimeType = dataCursor                                   .getString(dataCursor                                           .getColumnIndex(ContactsContract.Data.MIMETYPE));                           if (ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE                                   .equals(mimeType)) {                               //电话号码                               dataCursor                                       .getString(dataCursor                                               .getColumnIndex(ContactsContract.Data.DATA1));                           } else if (ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE                                   .equals(mimeType)) {                               //邮件                               dataCursor                                       .getString(dataCursor                                               .getColumnIndex(ContactsContract.Data.DATA1));                           } else if (ContactsContract.CommonDataKinds.Im.CONTENT_ITEM_TYPE                                   .equals(mimeType)) {                               //即时消息                           } else if (ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE                                   .equals(mimeType)) {                               //名字                               dataCursor                                       .getString(dataCursor                                               .getColumnIndex(ContactsContract.Data.DATA1));                           } else if (ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE                                   .equals(mimeType)) {                               //头像                               byte[] data = dataCursor                                       .getBlob(dataCursor                                               .getColumnIndex(ContactsContract.Data.DATA15));                               BitmapFactory.decodeByteArray(data, 0, data.length);                           } else if (ContactsContract.CommonDataKinds.Nickname.CONTENT_ITEM_TYPE                                   .equals(mimeType)) {                               //昵称                           }                       }                   }                   if (dataCursor != null) {                       dataCursor.close();                       dataCursor = null;                   }               }              if (contactCursor != null) {               contactCursor.close();               contactCursor = null;           }          }  

    3.更新（Update）

[java]  view plain  copy ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();           ContentProviderOperation op1 = ContentProviderOperation                   .newUpdate(ContactsContract.Data.CONTENT_URI)                   .withSelection(                           ContactsContract.Data.RAW_CONTACT_ID + "=? and "                                   + ContactsContract.Data.MIMETYPE + "=?",                           new String[] {                                   String.valueOf(contactId),                                   ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE })                   .withValue(                           ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME,// 对应data表中的data1字段                           "小明").build();           ops.add(op1);              ContentProviderOperation op2 = ContentProviderOperation                   .newUpdate(ContactsContract.Data.CONTENT_URI)                   .withSelection(                           ContactsContract.Data.RAW_CONTACT_ID + "=? and "                                   + ContactsContract.Data.MIMETYPE + "=?",                           new String[] { String.valueOf(contactId),                                   ContactsContract.CommonDataKinds.Phone.MIMETYPE })                   .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER,// 对应data表中的data1字段                           "12367712322").build();           ops.add(op2);              ContentProviderOperation op3 = ContentProviderOperation                   .newUpdate(ContactsContract.Data.CONTENT_URI)                   .withSelection(                           ContactsContract.Data.RAW_CONTACT_ID + "=? and "                                   + ContactsContract.Data.MIMETYPE + "=?",                           new String[] { String.valueOf(contactId),                                   ContactsContract.CommonDataKinds.Phone.MIMETYPE })                   .withValue(ContactsContract.CommonDataKinds.Email.ADDRESS,// 对应data表中的data1字段                           "test@email.com").build();           ops.add(op3);              try {               context.getContentResolver().applyBatch(ContactsContract.AUTHORITY,                       ops);           } catch (Exception e) {               e.printStackTrace();           }        4.删除（Delete）

[java]  view plain  copy ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();                   // 先删除子表Contacts中的数据                   ops.add(ContentProviderOperation                           .newDelete(ContactsContract.Contacts.CONTENT_URI)                           .withSelection(                                   ContactsContract.Contacts._ID + "=?",                                   new String[] { String.valueOf(mContactId) })                           .build());                   // 然后删除子表Data中的数据                   ops.add(ContentProviderOperation                           .newDelete(ContactsContract.Data.CONTENT_URI)                           .withSelection(                                   ContactsContract.Data.RAW_CONTACT_ID + "=?",                                   new String[] { String.valueOf(mContactId) })                           .build());                   // 最后删除父表RawContacts中的数据                   ops.add(ContentProviderOperation                           .newDelete(ContactsContract.RawContacts.CONTENT_URI)                           .withSelection(                                   ContactsContract.RawContacts.CONTACT_ID                                           + "=?",                                   new String[] { String.valueOf(mContactId) })                           .build());                   try {                       getContentResolver().applyBatch(                               ContactsContract.AUTHORITY, ops);                   } catch (Exception e) {                       e.printStackTrace();                   }  

    5.根据联系人电话号码查询名字，头像等等。

[java]  view plain  copy //根据联系人电话号码查询名字       public static String queryNameFromContactsByNumber(Context context,               String number) {           String name = null;           if (context != null && number != null && !"".equals(number.trim())) {               Uri uri = Uri.withAppendedPath(                       ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI,                       number);               Cursor nameCursor = context.getContentResolver().query(uri,                       new String[] { "display_name" }, null, null, null);               if (nameCursor != null) {                   if (nameCursor.getCount() > 0) {                       nameCursor.moveToFirst();                       name = nameCursor.getString(0);                   }               }           }           return name;       }   [java]  view plain  copy //根据联系人电话查询头像   public Bitmap queryPhotoFromContactsByNumber(Context context, String number) {           Bitmap bitmap = null;           if (context != null && number != null && !"".equals(number.trim())) {               Uri numberUri = Uri.withAppendedPath(                       ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI,                       number);               ContentResolver cr = context.getContentResolver();               Cursor numberCursor = cr.query(numberUri,                       new String[] { "contact_id" }, null, null, null);               if (numberCursor != null) {                   if (numberCursor.getCount() > 0) {                       numberCursor.moveToFirst();                       long mContactId = numberCursor.getLong(0);                       Uri contactUri = ContentUris.withAppendedId(                               ContactsContract.Contacts.CONTENT_URI, mContactId);                       InputStream is = ContactsContract.Contacts                               .openContactPhotoInputStream(cr, contactUri);                       if (is != null) {                           bitmap = BitmapFactory.decodeStream(is);                           numberCursor.close();                       }                   }               }           }           return bitmap;         

    6.通过raw_contacts的字段version，监听联系人的变化

[java]  view plain  copy /**       * <br>       * <b> Description: </b> 在raw_contacts表中获得联系人的version，如果联系人有更改，则version会变化       *        * @return int 联系人的version       */       public static int getContactVersion(Context context, long contactId) {           Cursor cursor = context.getContentResolver().query(                   ContactsContract.RawContacts.CONTENT_URI,                   new String[] { ContactsContract.RawContacts.CONTACT_ID,                           ContactsContract.RawContacts.VERSION },                   ContactsContract.RawContacts.CONTACT_ID + "=?",                   new String[] { String.valueOf(contactId) }, null);           int version = 0;           if (cursor != null && cursor.getCount() > 0) {               cursor.moveToFirst();               version = cursor.getInt(cursor                       .getColumnIndex(ContactsContract.RawContacts.VERSION));           }           if (cursor != null) {               cursor.close();               cursor = null;           }           return version;       }         到这儿联系人的Insert,Query,Update,Delete四大基本数据操作已经完成。
