怎么在android里边用字符串变量来查询sqlite数据库中的值

Question

请问怎么在android里边用字符串变量来查询sqlite数据库中的值呢？
在查询的时候总是没有单引号，导致查询出错，试了好多办法都没有效果

    int getIntContentByColumnName(String conditionColumnName,String condition,String resultColumnName){
        int the_int_content = 0;
        //cursor = db.rawQuery("select "+conditionColumnName+" from wordlib "+" where "+conditionColumnName+"=?",new String[]{condition});
        cursor = db.query("wordlib", null, conditionColumnName+" == "+condition, null, null, null, null);
        if (cursor.moveToFirst()) {
            do {
                the_int_content = cursor.getInt(cursor.getColumnIndex(resultColumnName));
            } while (cursor.moveToNext());
        }
        cursor.close();
        return the_int_content;
    }
