Android利用ContentProviderOperation添加联系人

Android添加联系人有两种方式：

1. 直接调用插入语句，先插入一个空Item，得到一个id，然后给这个id对应的插入其他信息，如姓名，号码，邮件等；

2. 利用ContentProviderOperation， 在系统应用Phonebook中就是采用这种方式， 代码如下：

实现了插入姓名，号码以及头像。

     private boolean saveUpdatedPhoto(long rawContactId, File photoFile) {
         final Uri outputUri = Uri.withAppendedPath(ContentUris.withAppendedId(
                 RawContacts.CONTENT_URI, rawContactId),
                 RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
         boolean result = false;
         try {
             final FileOutputStream outputStream = getContentResolver()
                     .openAssetFileDescriptor(outputUri, "rw")
                     .createOutputStream();
             try {
                 final FileInputStream inputStream = new FileInputStream(
                         photoFile);
                 try {
                     final byte[] buffer = new byte[16 * 1024];
                     int length;
                     int totalLength = 0;
                     while ((length = inputStream.read(buffer)) > 0) {
                         outputStream.write(buffer, 0, length);
                         totalLength += length;
                     }
                     result = true;
                 } finally {
                     inputStream.close();
                 }
             } finally {
                 outputStream.close();
                 photoFile.delete();
             }
         } catch (IOException e) {
             result = false;
         }
         return result;
     }

     public void addContact(String name, CharSequence phoneNumber1,
             CharSequence phoneNumber2, String email1, String email2, String im,
             String nickname) {
         final ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();
         ContentProviderOperation.Builder builder = null;
         int rawContactIndex = 0;

         builder = ContentProviderOperation.newInsert(RawContacts.CONTENT_URI);

             operationList.add(builder.build());
         }

         if (!TextUtils.isEmpty(email2)) {
             builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);
             builder.withValueBackReference(Email.RAW_CONTACT_ID,

         builder.withValue(Im.DATA, im);
         operationList.add(builder.build());

         // Add Nickname info.
         builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);
         builder.withValueBackReference(Nickname.RAW_CONTACT_ID, rawContactIndex);
         builder.withValue(Data.MIMETYPE, Nickname.CONTENT_ITEM_TYPE);

         try {
             getContentResolver().applyBatch(ContactsContract.AUTHORITY,
                     operationList);
             // Get raw_contact_id
             Cursor cc = getContentResolver().query(RawContacts.CONTENT_URI,
                     null, "display_name=?", new String[] { name }, null);
             cc.moveToFirst();
             // Insert photo for the contact.
             saveUpdatedPhoto(cc.getLong(cc.getColumnIndex("_id")), new File(
                     "/sdcard/DCIM/Camera/ContactPhoto-IMG_19700104_013154.jpg"));
         } catch (RemoteException e) {
         } catch (OperationApplicationException e) {
         }
     }

基本思路是先插入除头像以外的其他信息，然后获得raw_contact_id,再给这个id插入头像，具体方法是saveUpdatedPhoto（）。

Note：本人不太清楚能不能像插入姓名一样插入头像，所以才想出了这么一招，如果谁有更好的方法，不需要查询获得id就可以直接插入头像，共享一哈。
