android - 在 SearchView AutoCompleteTextView 中搜索包含特定字符的文本

Question

我正在尝试修改 open source dictionary project它使用 ActionBarSherlock SearchView$SearchAutoComplete。例如，我有一个名为“Google Play”的条目。 SearchView 能够在我键入“Google”时返回建议，但如果我搜索“Play”则不会出现这种情况。如何使 SearchView 能够搜索包含文本的条目？

        public boolean onQueryTextChange(String newText) {
            if (MdxDictBase.isMdxCmd(newText)){
                currentEntry.setEntryNo(DictEntry.kSystemCmdEntryNo);
            }
            if (!skipUpdateEntryList) {
                dict.locateFirst(newText, true, true, true, false, currentEntry);
                syncHeadwordList();
            }
            skipUpdateEntryList = false;
            return true; //return false if want the system provide a suggestion list?
        }

这是我 found from here 的 Cursor 查询.

public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
        Log.d(TAG, "Got query:" + uri.toString());
        if (uri.getPath() != null && uri.getPath().startsWith(SEARCH_PATH)) {
            if (fCurrentDict != null && fCurrentDict.isValid()) {
                String query=uri.getLastPathSegment();
                if (query!=null && query.length()>0){
                    DictEntry entry = new DictEntry(0, "", fCurrentDict.getDictPref().getDictId());
                    if (query != null && query.length() > 0)
                        fCurrentDict.locateFirst(query, true, false, true, false, entry);
                    if (entry.isValid()) {
                        String limit = uri.getQueryParameter(SearchManager.SUGGEST_PARAMETER_LIMIT);
                        int maxResultCount = 20;
                        if (limit != null && limit.length() > 0) {
                            try {
                                maxResultCount = Integer.parseInt(limit);
                            } catch (NumberFormatException e) {
                                e.printStackTrace();
                            }
                        }
                        ArrayList<DictEntry> entryList = new ArrayList<DictEntry>();
                        fCurrentDict.getEntries(entry, maxResultCount, entryList);
                        String[] columns = new String[]{
                                BaseColumns._ID,
                                SearchManager.SUGGEST_COLUMN_TEXT_1,
                                SearchManager.SUGGEST_COLUMN_INTENT_DATA_ID,
                                SearchManager.SUGGEST_COLUMN_SHORTCUT_ID};
                        MatrixCursor cursor = new MatrixCursor(columns, maxResultCount);
                        Object[] row;
                        for (DictEntry cur_entry : entryList) {
                            String intentDataId = String.format("%d_%d_%s", cur_entry.getDictId(), cur_entry.getEntryNo(), cur_entry.getHeadword());
                            row = new Object[]{cur_entry.hashCode(), cur_entry.getHeadword(), intentDataId, SearchManager.SUGGEST_NEVER_MAKE_SHORTCUT};
                            cursor.addRow(row);
                        }
                        return cursor;
                    }
                }
            }
        }
        return null;
    }

这是我 found from here 中的 locateFirst 方法.

/**
     * Locates the first entry that match the specified headword
     *
     * @param headword     Headword to be searched for
     * @param convertKey   Convert the given headword into different Chinese form according to dictionary settings?
     * @param partialMatch Match partial of the headword. For example "abc" can be matched with "abd" headword search
     * @param entry        The matched entry if found
     * @return Return kMdxSuccess when succeed, otherwise return error codes.
     */
    public synchronized int locateFirst(String headword, boolean convertKey, boolean partialMatch, boolean startWithMatch, boolean bestMatch, DictEntry entry) {
        if (isValid()) {
            return locateFirstN(headword, convertKey, partialMatch, startWithMatch, bestMatch, entry);
        } else {
            return kMdxDatabaseNotInited;
        }
    }

在 TextChanged 事件上使用 .Contains 字符串方法。然后根据该方法执行所需的搜索。希望对你有帮助
