Es tut es nicht. Aber ich habe einen Weg gefunden, den ContentProvider abzufragen. Ich habe die Quelle von SuggestionsAdapter von API 17 untersucht, wo die Abfrage ausgeführt wird, und bekam eine Idee, diese Methode zu ersetzen. Außerdem habe ich festgestellt, dass der SuggestionsAdapter von ActionbarSherlock Ihre SearchableInfo nicht verwendet.
bearbeiten com.actionbarsherlock.widget.SuggestionsAdapter in Ihrem ActionBarSherlock Projekt:
Fügen Sie eine Zeile
private SearchableInfo searchable;
in Konstruktor hinzufügen
this.searchable = mSearchable;
ersetzen getSuggestions Methode mit dieser:
public Cursor getSuggestions(String query, int limit) {
if (searchable == null) {
return null;
}
String authority = searchable.getSuggestAuthority();
if (authority == null) {
return null;
}
Uri.Builder uriBuilder = new Uri.Builder()
.scheme(ContentResolver.SCHEME_CONTENT)
.authority(authority)
.query("") // TODO: Remove, workaround for a bug in Uri.writeToParcel()
.fragment(""); // TODO: Remove, workaround for a bug in Uri.writeToParcel()
// if content path provided, insert it now
final String contentPath = searchable.getSuggestPath();
if (contentPath != null) {
uriBuilder.appendEncodedPath(contentPath);
}
// append standard suggestion query path
uriBuilder.appendPath(SearchManager.SUGGEST_URI_PATH_QUERY);
// get the query selection, may be null
String selection = searchable.getSuggestSelection();
// inject query, either as selection args or inline
String[] selArgs = null;
if (selection != null) { // use selection if provided
selArgs = new String[] { query };
} else { // no selection, use REST pattern
uriBuilder.appendPath(query);
}
if (limit > 0) {
uriBuilder.appendQueryParameter("limit", String.valueOf(limit));
}
Uri uri = uriBuilder.build();
// finally, make the query
return mContext.getContentResolver().query(uri, null, selection, selArgs, null);
}
Jetzt fragt es meinen ContentProvider ab, stürzt aber mit dem Standardadapter ab und sagt, dass keine layout_height eine XML-Datei von der Support-Bibliothek lädt. Also müssen Sie benutzerdefinierte SuggestionsAdapter verwenden. Dies ist, was für mich gearbeitet:
import com.actionbarsherlock.widget.SearchView;
import android.app.SearchManager;
import android.app.SearchableInfo;
import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.support.v4.widget.CursorAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public final class DrugsSearchAdapter extends CursorAdapter
{
private static final int QUERY_LIMIT = 50;
private LayoutInflater inflater;
private SearchView searchView;
private SearchableInfo searchable;
public DrugsSearchAdapter(Context context, SearchableInfo info, SearchView searchView)
{
super(context, null, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
this.searchable = info;
this.searchView = searchView;
this.inflater = LayoutInflater.from(context);
}
@Override
public void bindView(View v, Context context, Cursor c)
{
String name = c.getString(c.getColumnIndex(SearchManager.SUGGEST_COLUMN_TEXT_1));
TextView namet = (TextView) v.findViewById(R.id.list_item_drug_name);
namet.setText(name);
String man = c.getString(c.getColumnIndex(SearchManager.SUGGEST_COLUMN_TEXT_2));
TextView manuf = (TextView) v.findViewById(R.id.list_item_drug_manufacturer);
manuf.setText(man);
}
@Override
public View newView(Context arg0, Cursor arg1, ViewGroup arg2)
{
return this.inflater.inflate(R.layout.list_item_drug_search, null);
}
/**
* Use the search suggestions provider to obtain a live cursor. This will be called
* in a worker thread, so it's OK if the query is slow (e.g. round trip for suggestions).
* The results will be processed in the UI thread and changeCursor() will be called.
*/
@Override
public Cursor runQueryOnBackgroundThread(CharSequence constraint) {
String query = (constraint == null) ? "" : constraint.toString();
/**
* for in app search we show the progress spinner until the cursor is returned with
* the results.
*/
Cursor cursor = null;
if (searchView.getVisibility() != View.VISIBLE
|| searchView.getWindowVisibility() != View.VISIBLE) {
return null;
}
try {
cursor = getSuggestions(searchable, query, QUERY_LIMIT);
// trigger fill window so the spinner stays up until the results are copied over and
// closer to being ready
if (cursor != null) {
cursor.getCount();
return cursor;
}
} catch (RuntimeException e) {
}
// If cursor is null or an exception was thrown, stop the spinner and return null.
// changeCursor doesn't get called if cursor is null
return null;
}
public Cursor getSuggestions(SearchableInfo searchable, String query, int limit) {
if (searchable == null) {
return null;
}
String authority = searchable.getSuggestAuthority();
if (authority == null) {
return null;
}
Uri.Builder uriBuilder = new Uri.Builder()
.scheme(ContentResolver.SCHEME_CONTENT)
.authority(authority)
.query("")
.fragment("");
// if content path provided, insert it now
final String contentPath = searchable.getSuggestPath();
if (contentPath != null) {
uriBuilder.appendEncodedPath(contentPath);
}
// append standard suggestion query path
uriBuilder.appendPath(SearchManager.SUGGEST_URI_PATH_QUERY);
// get the query selection, may be null
String selection = searchable.getSuggestSelection();
// inject query, either as selection args or inline
String[] selArgs = null;
if (selection != null) { // use selection if provided
selArgs = new String[] { query };
} else { // no selection, use REST pattern
uriBuilder.appendPath(query);
}
if (limit > 0) {
uriBuilder.appendQueryParameter("limit", String.valueOf(limit));
}
Uri uri = uriBuilder.build();
// finally, make the query
return mContext.getContentResolver().query(uri, null, selection, selArgs, null);
}
}
Und setzen Sie diesen Adapter in Suche
searchView.setSuggestionsAdapter(new DrugsSearchAdapter(this, searchManager.getSearchableInfo(getComponentName()), searchView));
Vielen Dank, dass Sie sich die Zeit genommen haben, diese großartige Antwort zu schreiben :) –
