如何创建SearchRecentSuggestionsProvider？
提问于 2013-05-19 17:48:30
我的代码：
提供者说明：
<provider android:name=".searchprovider.MySuggestionProvider"
android:authorities="com.example.music.store.searchprovider.MySuggestionProvider"
android:exported="false" ></provider>爪哇：
package com.example.music.store.searchprovider;
import android.content.SearchRecentSuggestionsProvider;
import android.database.Cursor;
import android.database.MergeCursor;
import android.net.Uri;
import android.util.Log;
public class MySuggestionProvider extends SearchRecentSuggestionsProvider {
public final static String AUTHORITY = "com.example.music.store.searchprovider.MySuggestionProvider";
public final static int MODE = DATABASE_MODE_2LINES | DATABASE_MODE_QUERIES;
public MySuggestionProvider() {
super();
setupSuggestions(AUTHORITY, MODE);
}
@Override
public Cursor query(Uri uri, String[] projection, String sel,
String[] selArgs, String sortOrder) {
Cursor recentCursor = super.query(uri, projection, sel, selArgs,
sortOrder);
Cursor[] cursors = new Cursor[] { recentCursor, null};
Log.e("CUR", cursors[0].toString());
return new MergeCursor(cursors);
//retrieves a custom suggestion cursor and returns it
}
}但是当我运行这个时，我看不到我的提供者。(SearchManager)getBaseContext().getApplicationContext().getSystemService(Context.SEARCH_SERVICE)；if (searchManager != null) { List searchables = searchManager.getSearchablesInGlobalSearch()；
SearchableInfo info = searchManager.getSearchableInfo(getComponentName());
for (SearchableInfo inf : searchables) {
Log.e("nese",inf.getSuggestAuthority());

在可搜索活动中，需要将每个搜索查询保存在DB中：
@Override
protected void onNewIntent(Intent intent) {
setIntent(intent);
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
//use the query to search your data somehow
SearchRecentSuggestions suggestions =
new SearchRecentSuggestions(this,
RecentSuggestionsProvider.AUTHORITY,
RecentSuggestionsProvider.MODE);
suggestions.saveRecentQuery(query, null);
}
