Android如何把SearchManager和User Dictionary联系在一起

如何把SearchManager和UserDictionary联系在一起？

先了解一下Search



1)Inyour

<activity>

,anintentfilter,andareferencetoa

searchable.xml

file(describedbelow):

<intent-filter>

<actionandroid:name="android.intent.action.SEARCH"/>
<categoryandroid:name="android.intent.category.DEFAULT"/>
</intent-filter>

<meta-dataandroid:name="android.app.searchable"
android:resource="@xml/searchable"/>

2)AcontentproviderthatcanprovidesearchsuggestionsaccordingtotheURIsandcolumnformatsspecifiedbytheSearchSuggestionssectionoftheSearchManagerdocs:

<!--Providessearchsuggestionsforwordsandtheirdefinitions.-->
<providerandroid:name="DictionaryProvider"
android:authorities="dictionary"
android:syncable="false"/>

Inthe[code]searchable.xml

为了让search的范围可以包含dictionary,我们需要做：

ImplementasearchinterfaceusingAndroid'ssearchframework
ProvidecustomsearchsuggestionsandoffertheminQuickSearchBox
CreateanSQLitedatabaseandanFTS3tableforfull-textsearches
Createacontentprovidertoperformallsearchandsuggestionqueries
UseSimpleCursorAdaptertobinddatafromaCursortoaListView.

事实上，searchframework并没有提供搜索用户添加的数据的API，为了达到我们的目的，
必须使用支持我们的数据相关的API。怎么说呢？比如说，数据存在SQLitedatabase，那么，
就应该使用android.database.sqliteAPIs来完成searches。
