Android开发——Android搜寻框架(二)
Android开发——Android搜索框架(二)
1.创建搜索建议提供者
Android已经为我们创建了一个默认的,我们只需要继承 SearchRecentSuggestionProvider 就稍做修改就可以了。
见代码:
1:
import android.content.SearchRecentSuggestionsProvider;
2:
3: /**
4: * 搜索提示
5: *
6: * @author Hanguo
7: * http://t.sina.com.cn/halzhang
8: * @version 2011-1-5上午11:51:39
9: */
10: public class SearchSuggestionsProvider extends SearchRecentSuggestionsProvider {
11: //记住这个哦
12: public final static String AUTHORITY = "searchprovider" ;
13:
14: public final static int MODE = DATABASE_MODE_QUERIES;
15:
16: public SearchSuggestionsProvider() {
17:
setupSuggestions(AUTHORITY, MODE);
18:
}
19:
}
2.配置searchable.xml
1: <? xml version ="1.0" encoding ="utf-8" ?>
2: < searchable xmlns:android ="http://schemas.android.com/apk/res/android"
3: android:label ="@string/search_label"
4: android:hint ="@string/search_hint"
5: android:searchSettingsDescription ="@string/search_settings_description"
6: android:searchSuggestAuthority ="searchprovider"
7: android:searchSuggestIntentAction ="android.intent.action.SEARCH"
8: android:searchSuggestThreshold ="1"
9: android:includeInGlobalSearch ="true"
10: android:searchSuggestSelection =" ?"
11: >
12: </ searchable >
参数说明:
android:searchSuggestAuthorith
此属性的值就是SearchSuggestAuthorith中的AUTHORITH了。
android:searchSuggestIntentAction
此属性定义了当我们选中搜索提示的内容时发生的目的动作。
android:searchSuggestThreshold
此属性定义了至少输入几个字符时才会弹出提示
android:includeInGlobalSearch
是否将内容加入android的全局搜索。true,加入。
android:searchSuggestSelection
定义搜索时参数的占位符
