さまざまな条件を持つクエリを実行しようとしていますが、例外が発生しています。

bind or column index out of range

ContentProvider からのクエリは次のとおりです。

@Override
public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
    SQLiteQueryBuilder queryBuilder = new SQLiteQueryBuilder();
    int uriType = sURIMatcher.match(uri);
    switch (uriType) {
    case RESPONSEVIEW2_SELECTION_10:
        queryBuilder.setTables(RESPONSES_VIEW);
        String activeUserKey = getActiveUserId();;
        String outerSelection = 
                "(((" + PeerCreatedDataColumns.SHARED + "=" + "" + trueId + "" + ") OR " 
                + "(" + PeerCreatedDataColumns.AUTHORHASH + "=" + "'" + activeUserKey + "'" + ")) AND (" 
                + "(" + ResponsesColumns.PRIMARYMATCH + "= '*'" + ") OR " 
                                    // '*' is defined by the program, hopefully not in conflict with anything built-in
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '?') OR " 
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '" + selectionArgs[0] + "%') OR " 
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '%" + selectionArgs[0] + "') OR " 
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '%" + selectionArgs[0] + "%'" + ")))";
        Log.d(DEBUG_TAG, "query " + outerSelection);
        Cursor cursor10 = queryBuilder.query(mDB.getReadableDatabase(), projection, outerSelection, selectionArgs,
                null, null, sortOrder);
        cursor10.setNotificationUri(getContext().getContentResolver(), uri);
        Log.e(DEBUG_TAG, "responses_view2 should have better search function");
        return cursor10;
    case ROW_SELECTION_11:
        queryBuilder.setTables(RESPONSES_VIEW);
        Log.e(DEBUG_TAG, "responses_view2 should have better search function");
        queryBuilder.appendWhere(PeerDatabase._ID + "=" + uri.getLastPathSegment());
        Cursor cursor11 = queryBuilder.query(mDB.getReadableDatabase(), projection, selection, selectionArgs, null,
                null, sortOrder);
        cursor11.setNotificationUri(getContext().getContentResolver(), uri);
        return cursor11;
    ...
    }
}

エラーの原因と思われる Cursor Loader を次に示します。

public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    if (search == null) {
        return null;
    } else {
        String[] selectArgs = { search };
        return new CursorLoader(getActivity(), table, createProjection, "?", selectArgs, null);
    }
}

エラー全体は次のとおりです。

例外を見つけようとしていますが、このデータを照会するより良い方法があれば教えてください。

パラメータの数は?、selectionパラメータの文字列の数と一致する必要がありselectionArgsます。LogCat は、これらのカウントが一致しないことを示唆していますが、それを判断するのは困難です...

問題が見つかりました?。引用符で囲まないでください。そうしないと、文字通り疑問符を検索していることになります。これは正しくありません:

" like '?') OR "

代わりに次を使用します。

" like ?) OR "

ユーザー入力の場合search、SQL インジェクション攻撃から身を守る必要があります。

+ "(" + ResponsesColumns.PRIMARYMATCH + " like ?) OR " 
+ "(" + ResponsesColumns.PRIMARYMATCH + " like ?) OR " 
+ "(" + ResponsesColumns.PRIMARYMATCH + " like ?) OR " 
+ "(" + ResponsesColumns.PRIMARYMATCH + " like ?)))";

そして、次のような新しいselectionArgsパラメーターを作成します。

String search = selectionArgs[0];
String[] matchArgs = { search, search + "%", "%" + search, "%" + search + "%" };
Cursor cursor10 = queryBuilder.query(mDB.getReadableDatabase(), projection, 
            outerSelection, matchArgs, null, null, sortOrder);
