如何将预置联系人置顶？

[ANSWER]

具体置顶的方法介绍如下：

分别修改Contacts和ContactsProvider下的文件。

1.Contacts中修改一个文件:

文件路径为/packages/apps/Contacts/src/com/android/contacts/util/PreDefineContactsService.java

修改内容如下icfans：

photoId = getResources().getIdentifier(

final ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();

ContentProviderOperation.Builder builder;

- builder = ContentProviderOperation

- .newInsert(RawContacts.CONTENT_URI);

+ .newInsert(RawContacts.CONTENT_URI

+ .buildUpon()

+ .appendQueryParameter("caller_is_sticky",

+ "1").build()); //uri中添加条件caller_is_sticky = 1

2.ContactsProvider中修改四个文件：

1）在strings.xml文件中给置顶的联系人标识label(字符串的名字任取)，文件路径为/res/values/strings.xml

修改内容如下：

2）在TransactionContext.java文件中添加两个方法，文件路径为/packages/providers/ContactsProvider/src/com/android/providers/contacts/TransactionContext.java
