ऐसा नहीं है। लेकिन मुझे इसे आपके ContentProvider से पूछने का एक तरीका मिला है। मैंने एपीआई 17 से सुझाव एडाप्टर के स्रोत में देखा जहां क्वेरी निष्पादित हुई और इस विधि को बदलने का विचार मिला। इसके अलावा मैंने पाया कि एक्शनबार शेरलॉक के सुझाव एडाप्टर आपके SearchableInfo का उपयोग नहीं करता है।
अपने ActionBarSherlock परियोजना में com.actionbarsherlock.widget.SuggestionsAdapter संपादित करें:
एक लाइन
private SearchableInfo searchable;
निर्माता में
जोड़ें, जोड़ने
this.searchable = mSearchable;
इस एक साथ getSuggestions विधि बदलें:
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);
}
अब यह मेरे ContentProvider से पूछताछ करता है लेकिन डिफ़ॉल्ट एडाप्टर के साथ क्रैश कहता है कि कोई लेआउट_हेइट समर्थन लाइब्रेरी से कुछ XML फ़ाइल लोड नहीं करता है। तो आपको कस्टम सुझाव एडाप्टर का उपयोग करना होगा। यह वही मेरे लिए काम किया है:

इस महान उत्तर को लिखने के लिए समय निकालने के लिए बहुत धन्यवाद :) –
