在使用SQL 查询时强制关闭

在查询标题开头为 n 的记录时，出现了强制关闭。

代码：

public Cursor search(String title) {
    Cursor mCursor =
            mDb.query(true, DATABASE_TABLE, new String[] {KEY_ROWID,
                    KEY_TITLE, KEY_BODY,KEY_CDATE,KEY_PASS}, KEY_TITLE + " LIKE" +" " + title +  '%', null,
                    null, null, null, null);
        if (mCursor != null) {
            mCursor.moveToFirst();
        }
        return mCursor;
 }

请在 n% 前后加上引号，如：

SELECT DISTINCT _id, title, body, cdate, passw FROM notes WHERE title LIKE “n%”

至于你说的代码，可以这样写：

 mDb.query(true, DATABASE_TABLE, new String[] {KEY_ROWID,
                    KEY_TITLE, KEY_BODY,KEY_CDATE,KEY_PASS}, KEY_TITLE + " LIKE '" +" " + title +  "%'", null,
                    null, null, null, null);
