help me out of this.

change

cursor cursor = db.rawquery("select * "+table_texts + " " + key_cate + " = '" + text_spinner1 + " ' " , null);

to

cursor cursor = db.rawquery("select * "+table_texts + " " + key_cate + " = '" + text_spinner1 + "'" , null); // or cursor cursor = db.rawquery("select * "+table_texts + " " + key_cate + " '" + text_spinner1 + "'" , null);
